notes for loading and shooting

Postby spurdude » Fri Feb 02, 2007 4:07 pm

eWell being new to the sport, I made very careful notes on my loadings and such. I loaded about 10 different "lots" of 5- 8 rounds all slightly different. even color coded them. I figured when I went shooting, I would have plenty to experiment with. But when I went shooting, Actually being there and in the act, I found some of my notes did'nt seem to match up with what I had in the box. plus none of my notes were consistant to each other. I did have some success, but left with rounds in the box and not really knowing what they were. I need to be more careful in writing down my stuff. Is there a ledger for loadings out there? what do you guys do? just a spiral notebook? Has anyone ever found themselves confused like me?

Get some inexpensive 22 round cartridge boxes for MidwayUSA. MCM RF 22.
They are around 2 bucks apiece and get some labels and you can keep 8 different loads separated for under $20.

I use one of the greatest inventions ever - the ziplock bag. Load one lot of ammo, place it in a ziplock, put in a slip of paper with note as to load, zip it shut and you are good to go. Won't get any ammo mixed up and you can take range notes on the slip of paper.

I keep a box of ziplocks on my reloading bench and use them a lot.

Don't load so many 'lots'.
You went to the range with (if my math is right) 50 to 80 rounds of ammunition, and you are just starting to look for a 'good load'.

Load five to eight rounds of each type, but just take three loadings...all identical except for powder charge. And keep the charges within three to five grains of each other.

If your lightest load is (say) 60 grains, load up some with 65 and some with 70. One of those will work better than the others, and will give you a 'direction' to proceed in.
(I would use a fine felt tip to put a minus sign on the primer of the 60 grainers, a plus sign on the 70 grainers, and a 0 on the 65's. The marks are there to read when shooting, but they disappear when you punch the spent primers out.)

None of them will give you results you can depend on unless they are as (absolutely) identical as you can make them. Then the only notes you need are the ones you write at the range to keep track of what happened.
(I write them on the back of the target that was used for a particular load. Three loads, three targets, with three sets of notes.)

Thanks Montana_Charlie; Good advice. This winter is kickin my butt! Missed alot of work, so I guess I was getting the cart,(no Pun) ahead of the horse by loading so many different "Lots". but a guy has to feel somewhat productive. I did find 4 loadings that gave me 2-3 inch groups. so I'll try to perfect them. What I was really after with this post, was to try and see what my fellow shooters keep their notes in/on. I am in the begining stages of developing a field notebook aimed(again, no pun intended) specificly toward, BPCR shooters. this would be a valuable tool, in my opinion, in load development. a book with pages where a guy could enter data on a load and another page where results of that load could be recorded. this would create an on going step by step reference of all progress made in an individuals endevors at BPCR shooting. I was just wondering what guys use. thanks

I use ziplock bags also, use a marker on bag with test load number, have small spiral note book with load number and all load info, with room at bottom for crono and test results. Works for me. Like mentioned above take 3 or 4 loadings, change 1 thing at a time. Good luck, I'm on test load 30, trying different things.

Sorry this is so long but I can't post scans of the sheets and labels.
Here's my system for load testing. It might work for you, might not. First I always load in increments of 5 or 10 rounds and use a box that has rows arranged in patterns of 5 or 10. If I am testing a total of more than 20 rounds I will load up at least five fouling rounds using bullets with slight defects. The foulers will be used when I sight in or wipe between strings. The 50 and 100 round MTM boxes are excellent. I use Avery 2X4 mailing labels to identify the content of a box. They are printed up with the following text:

Date ______ Caliber _______ Load Series__________
Case_____ Primer______Powder______ Bullet______
Row 1_________ Row 2_______ Row 3_________
Row 4_________ Row 5 _______ Row 6 ________
Row 7_________ Row 8________ Row 9 ________
Row 10________ Notes: _____________________
____________________________________________
____________________________________________


I downloaded the reduced 1000 yard target available at http://www.bpcr.net/index-a.htm and used Publisher (an older Mircosoft program) to create a data target that has the bull printed in the center of an 8 1/2 x 11 sheet of paper. At the bottom of the page I inserted a text box that has this information:

Date:_________Firearm:_________Cart:_______Bullet:_______Case:___
Wad:_________Powder:________Chrg:__________Primer:_____OAL____
Time:________Temp:________Humidity:_____Light:___________Wind:__
Blowtube:________Sights:___________Notes:_______________________
_____________________________________________________________
_____________________________________________________________
___________________________________________________Avg:______SD_____ES:____

The last element of the system is a page called a bullsheet. At the top are four small target images created from the reduced target and modified in MS Paint to be very faint gray instead of black. Next to each one are number places to enter the velocity of five shots, the average, hi, lo, ES and SD. The bottom of the page has a textbox with this information:

Date _________________ Place _____________ Time _____________
Firearm _________________ Cal. _____________ Range ____________ Sight ______
Temp. ______ Humidity. ______ Wind _________

Case _________ Primer ________ Powder _______ Bullet _________ Wad ________
Load Notes ____________________________________________________________
______________________________________________________________________

Chrg. 1______ Chrg. 2 ______ Chrg. 3 ________ Chrg. 4. _________
Notes
_____________________________________________________________
_____________________________________________________________
_____________________________________________________________

In use the system works like this. I transfer the pertinent information from the ammunition box label to the bottom of each target and the bullsheet. Number them 1 thru 4 and put them up at 100 yds. I also post a fifth target labeled "S" for sighters and fouling shots. I fire a couple of the fouling rounds on this target to check setting and foul the bore. I then fire five shots on the target that corresponds to the test rounds, record each velocity, and mark the shots impact on the corresponding target image on the bullsheet. When the targets are pulled they are stapled or clipped to the bullsheet. At home groups can be measured and analysed. All elements can then be punched and placed in a ring binder or scanned and placed in a computer file. The entire system is made up of elements that are free (the target image) and entirely customised to any system of testing that you want to use. The bullsheet alows you to analyse the effects of velocity variation and see how a group developed. To identify the load serie I use a combination of the caliber and the date it was loaded, 457021406. I also keep a log book in a small bound memo with details of the load series and analysis that includes notes on what I feel should be tested in the next series.
You can't always win. You won't always lose. But you can always be a gentleman (or a lady).

As I said earlier, my range notes are written on each applicable target.
Back at home, those are transferred to a simple Notepad file on my computer.

Each Notepad document applies to one of the bullets I have moulds for, and as it grows longer it shows the complete history of my results for that bullet design. Of course the entire document, or a portion of it, can be printed when a hard copy is needed.

Below is part of (beginning and end) of my 'history' for one bullet.
Targets showing the best groups have been saved, but the 'history' is sufficient for the poorer groups.

560 Grain PJ Creedmoor
Maximum charge suggested by the Wolfe formula is 80.03 grains
.................................................................................
Powder is GOEX Cartridge
Charge to be compressed to allow a seating depth (w/wad) of .675"

Sample compression amounts per powder charge are:
79-.265" / 82-.330" / 85-.390"

Cases As fired
Bullet dia. .460 (as cast) - thumb seated
Lube SPG
Primer CCI 250 (initially...Federal 200 also available)
.................................................................................

First Session: (30-1 Alloy)
Second group of three shot on May 4, 2006 (also see Rapid Fire and PGT bullets)

77 grains:
5 round 100 yd. group 2.00" high x 1.25" wide

Barrel 'moderately' clean to start, blow tubed 4 breaths.

All shots fired within 20 minutes.
No wind, sunny, Temperature 55.

Reasonably good results for a 'first try'.
.........................................................

Second Session: May 10, 06
Wind light & variable from 4 o'clock - Temperature 65 - partly cloudy

Fired three 5-round groups, blow tubed three breaths before each shot.
Barrel prep for each group was two patches (first one wet) then a fouling shot.

- Alloy 20-1 (estimated), bullets matched by weight for each 5-round group.
No visual defects permitted.

- All loaded cartridges run through taper crimp die.

- Primers - CCI 250 (LR magnum).

- All charges individually weighed.

- Vernier staff set at 55 points (USA-431 sight), range was 100 yards.

75 grains:
Roughly 'square' group 1.25" high by 1" wide. One flyer 2" below the group.
Possibly a good load...worth more testing.
Group centered and 1.5" above POA.

77 grains:
'Circular' group 2" high by 1.75" wide.
Useful load...might be worth more testing.
Group centered and 2.5" above POA

* Both groups above were fired on the six inch white-centered bull. Different globe inserts were used for the two groups, and this target is not very suitable for 100 yard shooting.
Therefore, groups may be better if fired with more consistent sighting.

79 grains:
'Horizontal' group 1" high by 2" wide with a flyer 2" above group.
Lack of vertical stringing may indicate consistent velocity.
Probably a good load, should try increasing powder by 1 or 2 grains.
Group slightly left and 1.5" above POA on solid 4-inch bull target.

(Need to get a chronograph...)

...............................................................

Third Session: Sept. 8, 2006
Wind light & variable from 12 o'clock - Temperature 80 - partly cloudy - Humidity 25

Alloy 25-1 Bullets matched by weight.
Lube SPG
Taper Crimped
Primer CCI 250
Staff (on USA-406 Soule) 6 points elevation & 2 minutes left windage
Range 100 yards
Target 4 inch black bull (Groups generally impacted low and left)

One wet (spit) patch thru barrel between shots.

75 grains:
Tight group 1.25" H X .75" W...with one flier 2" Hi and 2" Right.
Group center - 2.5" Low & 1.0" Left of POA

Chrony: Lo-1173, Hi-1209, Av-1187, ES-35.75, SD-14.76

Low power charge, but produces tightest groups of loads tried.


79 grains:
Loose group 1.0" H X 3.0" W (similar to group on May 10th)
Group center - 2.0" Low & 2.0" Left

Chrony: Lo-1172, Hi-1191, Av-1183, ES-19.50, SD-8.24

Most consistent velocities of loads tried today. Will try it again.


80 grains:
Loosest group today 3.0" H X 2.50" W (bullets possibly too soft)
Group Center - 2.0" Low & 1.0" Right ... but too poor to trust

Chrony: Lo-1132, Hi-1172, Av-1143, ES-39.49, SD-16.24

Should try this again, but with harder bullets. Surprising difference between 79 and 80 grains...?

...............................................................
Left out part of the file to reduce length, skipped to heading for upcoming session.
...............................................................

Fifth Session: DATE XX
Wind XX - Temperature XX - Clear/Cloudy - Humidity XX

Alloy 20-1 Bullets matched by weight
Lube SPG
Primer CCI 250
First use of Soule sight after modification to provide separate windage adjustment for aperture.
Preliminary settings will be;

Staff 9 points Elevation with Staff Windage centered
Aperture Windage matched to ladder sight (1 MOA left on scale)
Range 100 yards
Target TRY FIVE INCH BULL ?

75 grains:
80 grains:
85 grains:
