So the gist,
I have load some speer 45 Deep Curl 300 Grain bullets in CBC once fired brass with 30.1gn of Win 296 (the second lowest out of 5 loads in the Hornady load book) compressed some powder, a practice which I try to avoid. When I fired this load, which works beautifully with 300 gn XTPs, I immediately noticed a much heartier kick and signs of over pressure. I pulled the rest of the bullets and dropped most down to 27.7 (less than minimum load) and a few down to 28.5gn. I am pretty sure that even at 27.7 grains of 296 I am still compressing the powder slightly or if not they're at 99% capacity.
ISSUE #2
The CBC Brass stuck in the chamber with the factory loads, I usually just had to tap very hard on extraction bar to get them out, the hot load required a rod to tap them out of the cylinder. Anybody else notice this with CBC brass, The factory loads had no signs of over pressure, I assumed it was a caused by a cheaper brass alloy than usual.
I have read that CBC brass in .454 casull tends to be heavier, thus less case capacity, though I doubt enough to change case capacity by 4-5 grains of powder.
My Question, Has anybody noticed reduced case capacity with either speer 300 grain Deep Curl bullets or CBC brass and have you had any problems with CBC cases sticking in 454 Casull caliber?
