I would have to know what components are used in a rifle and its accuracy before claiming one better then another.
I like seeing the barrel company, bolt, buffer assembly, receiver manufacture and trigger listed. If there is cost cutting I want to know where.
Another reason I like assembling...
The angle of the bullet falling out of the sky would effect the actual bullet path inside the animal. How does a ethical hunter manage that at 775 yards.
Unless you have worked pulling targets at 600 yards or farther you don't have much of a clue.
I kept a Model 37 in the corners for many years. Cut a barrel back to twenty inches and added large peep or ghost ring type sights.
Used it for deer hunting and HD. Shot slugs very well.
Since I stopped hunting and don't play shotgun games, I keep a AR in the corner now. Much easier to...
You can have inexpensive stock pistols and shoot a bunch in speed oriented games, or you can get expensive accurate pistols or revolvers and shoot accuracy games such as Bullseye that don't require a high round count.
That amount of recoil is not helping your hand and wrist.
I'd consider crimping over the shoulder of a SWC. Plenty of case capacity for a light load. Start your load development at the low end due to the deeper seated bullet. It might look like a 44 Russian.
I'm a believer in keeping life...
I think your only hope for expansion at 850 FPS it to find a old swaged lead bullet. Swaged lead is very soft.
I'd bet the old FBI 150 grain LSWC HP was swaged.
ZERO bullets sold as Roze might have what you need. Cast.
A fired 380 cartridge works as a take down tool.
I needed to tune the tension on the extractor for reliable operation. Now it feeds most anything.
Deactivate the magazine safety will improve the trigger pull
I have tried two barrels on a suppresser and neither were threaded true.
Cold Steel makes a line of walking sticks and canes. I have used the axe head model for a couple years. Has the advantage of a hook/crook to hang on your arm if you need two hands for some reason. Have flown with it and no issues.
