Hello! I started doing some work with Trail Boss in bottle-neck cases in old military rifles. Here is one I loaded up on 8-27-05. Fired it in a German Model 88/05/14/38 Turk Conversion.
8mm Mauser
Lyman 323470 164 grain wheel weight gas check
40/60 % Alox/Beeswax homemade lube
9 grains (scale weight) Trail Boss
R-P 9 1/2 Remington large rifle primer
New (!) Herter's (Norma) casings
Did not chronograph, 50 yard loading
1.25 inch average for 3 shot groups at 50 yards from bench. Rifle barrel is like new.
I noted this load to IMR and right after I did some work with rifle loads began on their site. Coincidence? We need more development such as this!
