Old Bob Wrote:Wilson Combat's first try at converting .223 Rem to .30 Caliber was their 7.62x40WT cartridge. It was Bill Wilson's first attempt at making an efficient feral hog killin' cartridge. I've never used it to kill hogs but it has to be as good as or better than the .300BO with the right bullets. It is a good accurate round. I started using it in 3 gun matches with decent results. My groups with it were the same 1MOA or better with several different bullets (110 to 125grs). Even round-nosed .30 Carbine bullets shoot well in it. I use only one powder - A1680 & my own modified 5.56mm cases. The problem now, for me, WC seems to have put the 7.62X40WT off to the side & is focusing on the 300 HAM'R. So... I've been considering re-barreling my AR to 300 HAM'R but don't know if I ever will.
I thought the only place you could get 300 HAM'R barrels was from WC, but found out Shaw Barrels makes them too. Haven't checked ammo availability though...

Not too surprised that Shaw is chambering for the HAM'R as it is officially a SAAMI cartridge. https://saami.org/wp-content/uploads/202...uction.pdf
