Finally got my two lone wolf barrels. They had been on order since mid nov. I guess they came in stock a while ago but I had one of the barrels blind marked and engraved. I got one stock length .40 SW conversion barrel and one threaded blind marked 10mm barrel. My first impressions were that the lock up on both barrels is very tight. Next the barrel support seems to be very good. My stock barrel is a late model gen3 that has never givin me smiles even with hot loads. Also the chamber seems to be tighter. So here's the bad news, I have three standard loads that I shoot. 1st. 180 fmj at 1.25" that fits fine. 2nd my HD load 135 Nosler at 1.25". This also chambered and feed fine from the mag. The last load is a bear tooth 200gr HC at 1.26". Here's the problem, at that length the bullet hits the rifling before its fully seated. It's a pretty hot load that gives me 1230fps from the stock barrel (no smiles) so I really don't want to shorten things up. I really only plan on using the LW barrels at the range, and the 200gr BT are just for fishing trips. I really but want the barrels to make my brass last longer. I'll shoot them this week and give a report.
