Ideal .40 cal weight.

Post by Singleshot S.A. » Fri Mar 24, 2017 6:21 pm

My .40/65 Rolling Block Pedersoli has, I think, the potential to shoot well, or better than it is.
This is a re barrelled 45/70. Barrel type unknown. Possibly Green Mountain.

Obviously getting the right bullet is a good start to improving it, so my question is this............

What is the general consensus regarding bullet weight for a .410, 1:16 twist, 32 inch barrel. ?
I shoot straight Black powder with it and I can Breach seat or seat in the Case.
It is for purely 100, 200 yd Target, paper and gong at this stage. If I and the gun improve a bit, possibly 300 yd and then silhuette.
The most accurate load I have is a Saeco #640, which drops a 370 grn bullet cast at 40:1 so I can breach seat it.
Next is the Lyman #663, 405 grn which I seat in the case.

I would like to get myself a genuine tapered BS bullet sooner than later, but what weight.??
Is 400 grn about right ? Or a tad more, 400 - 425.
I do have a bit of trouble with my shooting shoulder, so no Elephant hunting projectiles for me.
If I were living in The States I would grab my self a couple of molds to try, or possibly some projectiles from a neighbourly fellow, but I am not, and the cost (in Oz) to experiment is far too great with the Exchange rate and postage.

All suggestions appreciated, as usual. Thanks, SS S.A.

I shoot a .40-65 Shiloh with a 1:16 twist barrel. My best shooting bullet at 200m is the Saeco #740 which is a little more than 400gr in 20:1. At further distances I like the BACO 400409M4 which weighs a few grains less than 400 when cast in 16:1.

I shoot a Shiloh 40/65 with a 16" twist and I shoot a Brooks Creedmoor style bullet with a reduced front band. It weighs 416 grains cast from 25:1. I have another 16 twist rifle with a Green Mountain barrel and it likes the Saeco #740 at 412 grains in 30:1

If you what to shoot out to 1-200 yards only with a GG bullet I would consider the RCBS 2-Cavity Bullet Mold 40-300-SP-CSA 40 Caliber (410 Diameter) 300 Grain Semi-Point. I have this mould for light loads in my .40-65 Browning BPCR and the .40-70 Shiloh for the younger shooters that I don't want to get bumped from recoil that is no fun for them. This bullet is a light and very good shooter in the .40-65 as well as the .40-70.

I had good luck with the lyman snover at 20/1 but took three moulds to find correct dia for my 40. Fouling control with your 32" bbl may be more important than bullet nose at 200 yds.

Thanks for the replies guys, I will check prices and shipping and availability.

I'm still, and will be for a long while, learning. The problem I have here is that there obviously aren't as many BP shooters here, and then some only shoot Muzzle load. Then, of those few that are really serious shooters, even fewer are actually any good. And of those few that are any good, there are not many that want to help. Yes they all give a few tit bits but never the whole story. Then I have to try and de cifer the information given and turn it into practical help. Haha. We're getting there, slowly.

Well, I'll be in your neck of the woods in a half year or so. I'd be glad to help with whatever I can. I'll be muzzleloading on this trip, but the two games are really pretty similar. I even use the same bullets and powder charges in both types of rifles.

Anyway, I'm looking forward to visiting Adelaide and seeing the sights and shooting the championships.

SingleShot S.A., the one thing I can tell you is that once you've gone even a little way down this road, the internet generates few useful pieces of information :D :D.

With respect to bullet weight, I have shot a 420gr Hoch bullet in my Shiloh. It was no where near as good as the 400gr Saeco, or the 400gr tapered Money. Possibly due to being a bit less stable, although maybe more likely the large meplat on that design. I would go heavier than the light Saeco bullet you have just to get a little better BC. You could always try an elliptical/prolate nosed bullet too. I just wouldn't go any longer than the 400gr Money as I believe it's sufficiently stable, but not overly so.

With respect to breech seating, the most accurate 200m BP bullet I've ever shot is the .38 cal, Baco Tapered Creedmoor. I don't think that it works well in my rifle due to the nose though, but just that the fit is probably close to ideal for my rifle's chamber.

You might want to try casting either of your bullets from 20-1 or 16-1.

I have 2 Browning 40/65's which shoot the same load. I use a Paul Jones money bullet that was designed for that chamber by, I believe, Dan Theodore. I cast to a hardness not a mixture - from 10 - 10.5 on the Brinnell hardness scale. Bullet comes in at 407 gn. Shot from the bench today in comp - 13 shots 10 to count 100m (110 yards), peep sights, scored at 100.9 - difficult as there was a lot of tearing.
For me there are 3 things to think about for the ideal bullet - barrel twist, chamber type (cut off taper or leade and freebore) bullet shape(straight or tapered).

singleshot sa,
possibly you don't listen when people tell you things.
possibly you fail to define what you need to know.
possibly you don't recognize people that do know.
possibly you don't recognize good advice when you get it.
I have found a number of south ozzies that know a lot, and will give willingly and freely.
you do them an injustice.
keep safe,
bruce.

Macca,
Are you using WANO PP or P?I have only used P in my Roller 40/65 16/1 Douglas ,best I can get is about 1.1/2 " @100yds.Do you find WANO a consistent powder?I have heard it can vary from batch to batch.All the experts say you should use Swiss ,I find the cost and availability makes it a pain to source.BTW an enviable group you have there.

Cheers Mal.

Hi Mal
For my 40/65's I use 64.5 grains of 2P Wano drop tubed no compression.
Changed my load about 3 weeks ago and it now shoots even tighter groups. Now neck size the first 3/8 of the case then run a 410 expander button through (hardly feel anything) size my bullets to 409 (hardly feel anything) Now they are a slip fit with no neck tension. I also moved from a 30 thou top wad to a 15 thou top wad. The pic of the target was shot with that load.

Thanks for that Macca,will give the 2P a try ,have tried a few projectiles ,Lyman taper,Lyman snover,Saeco 640,all with similar results,was given some 370gr Brooks two dia pills when I first got started in this evil science of BP they shot the tightest groups,but a Brooks mould landed in au is about $400.Will have to save up the pennies .

Cheers Mal.
