I have modern nice rifles for hunting large game. However, for deer, every year I use an old milsurp. I find it fun to work up a load etc... Great fun and success every year.
Anyway, I got a Steyr and Budapest M95 Mannlicher straight pull bolt rifle. Both are 8x56R carbines and great factory refurbishments. They have very strong actions. I got a lot of 205 grain, 1938 nazi ammo that shoots accurately and really wallops your shoulder.
I bought Lee dies and they came with reload data. Reload data for that caliber is quite difficult to find so I was pretty much stuck with Lee's and the Hornady 205 grain Spitzer, Prvi brass and Buffalo Arms 150 grain bullets.
In another forum, shooters grumbled about the watered down Lee load data, saying they had blow back in their face.
I'm wondering if that is what I expeirenced..... I loaded the 150 grain bullets up with Lee's max for IMR 3031, 4064, 4350, and 4831. The blow back in my face was awful, the bolt got filthy and there was often a few grains of unburned powder. The brass cases had soot rings around the necks and was unusually hot. Is this low pressure signs like I hear?
Same day TEST # 2, the Nazi ammo shot 5 rounds with clean cases and no blow back and kicked much harder and was much louder. The 205 grain bullets were loaded using mediocre 8x57 data as a guide (common for 8x56R shooters) and typically hotter. They (except for one weak load) did not create blow back and no sooty ring around the neck. Rifle was examined and in excellent condition, again 5 1938 nazi rounds shot fine. Am I likely expeirencing signs of low pressure from low powder charges (even though Lee's Max) not expanding the case neck tight enough to the chamber? No case necks were cracked, no case flattening, no bulged or flattened primers. I almost think that I should increase the charge one grain at a time until blow back ceases and the sooty ring disappears. Thoughts?
