Here's what I have:
-Newer Savage 114 with maybe 200 rds through it
-Brand New Federal Premium Brass, Winchester LRM primers, 67.0g H4831, Barnes 120 TTSX to a COAL 3.230 =/- .002 Books Maximums are 68.5g and 3.240 COAL
Past History
I started a load work up for the 150g about 2 yrs ago. I also found 2 sweet spots for a 120g that I noted and left to finish the 150g. I started at the beginning with once and twice fired brass and ultimately ended up having the same pressure problems that I'm having now with charges well below the max. During the last 1 1/2 yrs I sent the rifle into Savage twice to make sure it wasn't a headspace problem and after a blown primer broke the ejector pin. I got the rifle back late last year and its sat until a few days ago
So I draw my antelope Tag after 19 yrs and am going back to the 120g sweet spots (67.1 and 68.2) but this time with brand new brass to make sure it wasn't a primer pocket issue
I had 6 loads of 67.0, 67.1, 67.2, 68.1, 68.2, and 68.3 with book max being 68.5.
Fired 2 shots of Factory ammo to verify Zero with no problems
67.0g-I shoot all 4 rds of with no problems but certainly not the accuracy I had before.
67.1g-I shoot 3 of the 4 and the 4th has a slight leakage on the primer pocket, with poor accuracy on all
67.2g- I shoot the first one and the primer leakage is more significant and I stop the test.
I shot 3 of the same factory ammo with no problems.
I notice two burn marks on the bolt head one very slight and one a bit more, one that created some pitting
This morning I spoke with Barnes and there load for H4831 is 65-69g of IMR 4831. I told him specifically that I’m using H4831 and he said he uses it as well
My question is it possible that some rifles won’t take anywhere close to max values???
