I did something real stupid today.
I was playing around my 1928 ex-dragoon with D166 200 grain Lapua projectiles and IMR 4064. Max load is 43.4 according to Lee and 46 according to 1967 Lyman. I started at 41 and worked up to 43. 43 was bad so I was trying to figure out if 42 or 42.5 was better.
While shooting my wife came home from her mothers with all kinds of woman drama and pissed me off pretty good. I should have just stopped shooting for the day but i went back in and loaded 5 rounds at 52.5 grains!
I shot the first one and had a pierced primer. it was a little tough to extract but I have had similar problems with generic BL-C(2). I should have stopped and looked at my load book.
Shot another. and had same result. The rifle was kicking harder but it wasn't overwhelming.
I started thinking. WTH is wrong. I just shot at 53 and now Im at 52.5 why am I having pierced primers? This is a sign of overpressure. Oh well. I am below max. I will just finish these off.
The 4th one looked like it had a piece of my firing pin in it. I took the bolt apart and it looked perfect.
I shot the 5th one and went in and looked at my book. I was supposed to be at 42.5 not 52.5 Holy Smokes! I was at least 15% above MAX. What a dumbass.
I will say that the Mosin is a strong action. also PPU brass holds up very well. The cases only grew by .005. The primer pockets were loose but not to the point I chuck brass. I reloaded them at 42 grains and shot a 5 shot 1" group at 50 yards. one of the cases developed what looked like a future crack so I pitched all 5.
my take-a-way from this. If your shooting and something distracting happens. STOP. If you shoot one shot and have some big sign like a pierced primer. STOP and check your data.
I am lucky I did not learn the hard way.
My shot group FYI All 5 shots on PAPER with a perfect 16" shot group. one on each side and one in the middle.
43.4 grains is 50,000 psi according to LEE. i wonder what 52 is?
