I shoot cast semi-wadcutters, they look very similar to the picture you showed, and that is what it took to make them feed reliably.ASM826https://www.blogger.com/profile/04017388670319590449noreply@blogger.comtag:blogger.com,1999:blog-3274583756441452923.post-84366295984109950752018-01-30T02:43:54.280-05:002018-01-30T02:43:54.280-05:00If you down-load the mag, does it feed?
Check the ...If you down-load the mag, does it feed?<br />Check the rim dimensions of that brass. Might be out of spec.<br />Slide moves smoothly?<br />Try other mag brands/styles. For me, last resort would be Wilson, as they are designed to release the cartridge early, to fix/bandaid loading problems. They're not a controlled feed design, like JMB intended.<br />If all else fails, try a heavier recoil spring. (My benchmark is a steel frame Officers Model that will feed empty cases, but they run 22 lbs original, and 24 lb Wolfe.)<br /><br />Oh, forgot an important check for this problem! Measure OAL before and after loading attempt. Bullet setback will absolutely kill the loading cycle of Gov Mods. If it's more than a few thou, you have an ammo problem.Willhttps://www.blogger.com/profile/00722792638246578812noreply@blogger.comtag:blogger.com,1999:blog-3274583756441452923.post-27222796336829238212018-01-29T13:54:22.718-05:002018-01-29T13:54:22.718-05:00You need a steeper angle feed ramp for SWCs.
