Swiss black powder press, yes or no?

Post by Bossgun » Sun Jul 29, 2012 4:05 am

Here in Germany, the Swiss black powder is often used. Also, I have decided in favor because of the burn will be very good,
and the barrel can be cleaned very well.
Also, the pressing of the powder is discussed here. Since my results were mixed again and again (sometimes very good, then very large scatter)
I did this test, the squeeze has affected only the powder.

My details:
Rifle Sharps 1874 Bossgun by Pedersoli in .45-110 caliber
Sights: rear Sight with front Sight and level of Glässmer

Sleeve: Starline 73mm (2.8745) With Lyman Neck Sitzer, expanded to .456
Primer: Fed 215 mag
Powder: Swiss No. 4 or 1-1/2 Fg
Charge: 101 gains with Lyman Classic 55 and 24 "tube drope
Bullet: Homemade CF mold, Creedmore bullet, 566 grains, HBT 10, .459
Pan Lubing with SPG, Projectiles balanced to 0.5 Grains

Cartridge construction: in order from bottom to top,
101grains Swiss No.4 on drope tube
1 Walter-Wad 1,6mm ( 0.06 ) from handle to set the powder. 17.4 mm (0.6855) from the case mouth.
With Powder Compression Plugs to 2mm (.0785) is pressed. 15.4 mm (0.606)
A cardboard 1.4 mm (0.0545)
1 Walter Wad 0.8 mm (0.03)
1 Paper 0.4 mm (0.0155)
CF-level L1 = 100.50 mm (3.9575)
Very little applied crimped.
On leather sandbags placed at the front and rear shot, partly cloudy, 15 C°
I had 3 different charges
First without pressing
Second pressed with 2mm
Third pressed with 3mm
Each of 3 rounds

Primer: Fed 215 mag
Bossgun, you might want to consider using a primer the creates low brisance of the powder ignition.
The primers of choice here are the CCI BR2 rifle primer and the Federal GM150M Large Pistol Match

The 3rd target is nice. Looks like you have done your experimenting and the load came together with the compression and bullet

Bossman, in order of better groups ... it looks like:
1st Place - Federal Large Pistol
Tie - CCI BR2 and Federal 215 Mag
Do you want to do another test with the same recipe and primers?
Put a construction paper wad over the flash hole inside the cases.
Purpose? To determine if the ignition brisance is decreased with either the Fed LP - CCI BR2 and Fed 215 Mag to see if groups are smaller.
Also for posting your targets - they tell the true story! Danke Sehr!

Hy John,
thanks for the assessment. I'm going to try, but can take longer.

Bossgun, your loaded ammunition is a pleasure to behold!

I´m supposed to be able get 38 grains into my short Werder cav. carbine cases. But, even using a compression piston in my Forster press, I can only get 32 gr into the case. Accuracy seems to improve dramatically the more I compress the BP (the other noticeable improvement was to cast a cavity in the bullet base).
