I wouldn't think the shape of that bullet would cause any trouble. Have you tried other mags? (I am wondering if the mag you are using might have been damaged without you realizing it.)
No shock buff Deadaye...and I will check the recoil spring next time I shoot it...Cholla told me to check the ejection and see if the shell ejects 5-10 feet behind me...if not, I will change out the spring to another new 16 and grab a 14 just in case the ammo is too weak.....it is 7 years old but I don't think it has more than a 1000 rounds thru it...![]()
I'd try regular old hard ball (round nose) .45ACP before I did anything to the gun.
JMB designed the gun around a specific bullet - Try them first.
