Bought this elsewhere, was advertised as a .378. Finally got to try it out, & found it to drop at .385 instead. About 328 gr with 25-1. I can't use it, maybe you can. No markings anywhere. Looking at the alignment pins & holes, hasn't had the best of treatment either. Is what it is. Will send it for a $5 donation to this site, fair enough?
Please post an "I'll take it" AND send a PM too if you want it
