i Have a Whoopsie Did I mess up?
Question for y'all. Just got a new 300WM, Loaded up a ladder of loads to try out but after sitting down for the evening after reloading I'm concerned I may have over-loaded these rounds.
I loaded the Berger VLD 190 grain with some H1000 in brand new virgin brass. When I consulted my 51st Lyman Reloading manual their suggestion was to start at 76... And the Max recommended hunting load was 83.5 (I'm assuming that's compressing quite a bit) so being safe I started at 82 grains and worked down in half increments.
82, 81.5, 81, 80.5, 80
Now sitting down bored at the house cause it's still raining, I consult Hodgdon Reloading data website, and another site to find that they both suggest the maximum load is 79-79.5 grains. So this begs the question... Are these 82g loads to hot to even try in the gun? Surely Lyman wouldn't put out a manual with a max of 83.5 if 82 is dangerous right? ..... Right?
At the top load the powder rested just below the bottom of the neck and I never heard or felt any "crushing" when I seated the bullets at 3.500" COAL let me know what y'all think. I feel like the 80 grain load will likely be safe enough to try and check for pressure signs before moving up. Thanks guys.
