I have two Lonewolf barrels for my G35, a 9mm and 357sig. Both worked great and the 357 is a lots of fun. Then I started cast bullets (being cheap again) and purchased threaded barrel for my G36 (some day I will get a suppressor). That‘s were the problems started. The bullet I am casting is lee mold, 200 gr round nose flat point. It runs great in my 1911, 625 SW, and in the original glock barrel, but not in the wolf barrel. The barrel would not seat in the slide. I did lube all the bullets with a star luber/sizer. A fellow shooter and caster advised me to seat the bullet deeper (all rounds case gaged). Back at the press, I seated the bullet until the action closed correctly. Made fifty cartridges, all case gagged and back to the range. Every mag full one or two rounds would jam on the feed ramp. I put the original barrel back into the G36 and NO Problems. Same fellow shooter/caster gave me his cast cartridge a 200 gr SWC. They did great in the Glock barrel, but not the wolf barrel. Same problem, jammed against the feed ramp. Following week I tried some Berry 185 RNHB bullets and they feed from both barrels…. Is it the bullet design or is the chamber too tight???
