Was just experimenting today and decided to play around with some things on my Accura. I decided to play around with my load, and came up with one consisting of 110 grains of BH209 load, a 220 grain Bloodline, a Harvester Crush Rib Sabot for .458 bullets (https://www.harvestermuzzleloading....-crushed-rib-sabot-for-458-bullet-pack-qty-50 ), and a Federal 209A primer. I usually shoot a Winchester W209 primer, and have no shims on the firing pin bushing, as I don''t have any blowback until I am few+ rounds into a shot string. Anyway, with the Fed 209A I am using 0.012" worth of shims to get a 0.002" to 0.003" crush on a 0.295" and 0.0296" primer, which a majority of the Fed 209A primers measured.
Well, when I shot, I got the results posted below in the pics. My biggest concern is the primer and the blowback I got from it. If you look at the pic of the business end of the primer, there is some sort of strand left in the primer. You can't see it that well, but the primer was also extremely sooty, and it was just the first shot. The face of the primer cup has the imprint of the firing pin bushing in it, which you can see in one of the pics. I didn't take a pic of it, but the face of the firing pin bushing and frame were sooty as well.
Of special note, the petals of the sabot sheered off, which is not that big of a deal, I guess.
I am curious to hear your thoughts on how things got so messy with the crush I had on a first shot using a clean, Western 209 breech plug. Nothing was plugged up, and I had I don't have this issue on the first shot with no shims, no crush, and a W209 primer.
By the way, please understand that an o-ring in the primer pocket is not an option, because even with a 0.294" primer and no shims on the firing pin bushing, I can only close the action, and cannot cock the hammer of the rifle. So, please don't suggest this option.
