44-70-380 test

[Denali]

Looks like your getting results. But I gotta ask,is that all the powder it will hold? I been putting 76 gr Fg Kik in a 40-70 2.1" BN without a problem. What is its max capacity? bobw

Hi Bobw.

I wanted to try the "historical" load of 70 grs with the 380 first. Then i went to 75. The traditional 70gr load was significantly better. When i full resize my baco 348 reformed brass i can put about 77-78 gr in it and compress without bulging the case. Any more than that seems to affect chambering in my experience.

Down the road i'll try varying the charge in 1 grain increments to see what happens. One interesting note is that my 405 huntin bullet does crappy with 70 grs but shrinks down with 75.

My next testing is going to involve unresized cases only if i can get the 380 gibbs wrapped to a tight fit in the brass.
