I built mine in 223 currently shooting 80 gr Bergers. Great handgun. Hornady now has 80 ELD-X. I will be trying these out next week. Probably going to change the Pachmayr grip to something else.
Pachmayr grip was ok for smaller calibers, but had to go back to wood for the 375JDJ. Handgrip attachment bolt would bend till the trigger guard would slap your knuckles hard.
