[QUOTE="swampratt, post: 3046508, member: 15054"] You guys must realize different cases have different wall thickness. You must also realize these plated bullets are very soft lead and all the bearing surface of some bullet types is inside the case. If i was to set my crimp to .469" on my A* USA cases i would be pinching my bullet down to many thousandths under groove diameter. In my 45acp Accuracy would go to crap.. fouling will go way up. The chamber in this gun is quite large in fact at .472" with the .452" diameter bullet he is using the plunk test works great in fact there is a lot of wiggle room in that large chamber. Zero feed issues with those rounds he is making now. they slick right up the ramp and into the chamber. I stuck 5 in the magazine and racked the slide fast and chambered and ejected all of them like a champ. My 2 personal 45 acp's have large chambers and nice ramps and .472" is where my mouths are with a .452" lead SWC. My alloy is 1/3 wheel weight 2/3 soft lead. If i close the mouth more accuracy greatly suffers and leading goes way up. Same happens when I use the 230 gr Xtreme plated in my gun. Accuracy goes to crap.. in fact those Xtreme have not played nice with my gun yet as far as accuracy goes. I understand many guns may like .469" and tighter.. but you kind of need the gun in your possession and shoot it and see what results you get. [/QUOTE]
