    I cannot shoot hard cast lead, after 2-3 shots fired the slide won't go into battery. I read an article about reaming the the chamber to remove the lip at the edge of rifling, anyone with any advise. I tries 3 different brands of hard cast lead and 4 different cartridge overall length. The slide is only 1/16 of an inch from going into battery. I've shot several types of jacked bullets with no problem. Thanks

    Reloader,

    I don't know if it makes much difference as I have no experience (some but not much) with lead bullets. All I shoot in my SR1911 full size and Combat Commander is .452 Berry plated. I don't know how much the .001 would make in allowing the round to chamber. If you find out, please let me know. Thanks,

    Tommy

    My Tanfoglio Witness .45 is reluctant to chamber .452 hardcast bullets (they chamber with help from my hand on the slide). I think the chamber is 'on the snug side'. My fix is to swage the bullets to .451.

    I used to have a 1911 that didn't like to have a bare case edge slide up the feed ramp. It would hang up on the bottom of the ramp, I cured this by having just a hair of the lead shoulder above the case mouth and then it would slide right up. Don't have that problem with my SR45, is that what is happening to you or are they not going all the way in the chamber? Reread your first entry, like I said the SR45 doesn.t need that lip of lead, you might check your col. If enough of the lead shoulder is above the case mouth you would be held out of battery.

    You must be using 700x as your powder correct?

    chilly3479, not sure who you are referring to. If me, the answer is I have used 4.4 grns of 700X under 230 grn lead rnd nose.:)
