Magtech 260JSP what is the COL for this factory load. It feeds great. Does any body chamfer the outside of the 454 cases before loading ? At what COL does you gun feed the xtp/hp 300 grain. Do you know the address of a gunsmith that can do a feed job on the gun and not take a year to do it ,thanks,keith

keith,

I can't answer your question on the MagTec ammo. I'd suggest getting a good dial caliper and measuring it.
A caliper is one of those tools that should always be in a shooters tool box, or on the loading bench.

I debur inside and outside of all my cases when I trim them or the first time new cases are used. Just enough to break the sharpe edge on the case mouth.

He is the factory warranty gunsmith for LSI and Rossi lever guns. He did the action job and some other work on my Rossi .45 Colt. Took a bit over 8 weeks including shipping both ways.
Just be very specific what you want done, and don't have the springs lightened too much.
