Jody Waring Posted October 23, 2016 Share Posted October 23, 2016 I have been having some feeding issues with my .45 IPSC Classic division pistol. I am using a cast 230gr TC bullet and I am seating them so the shoulder is essentially even with the case mouth. Any longer and the round will not chamber properly as the bullet is hitting the lands. The malfunction is the round is flipping upwards (bullet first) and not chambering and the slide closes on the round. Are .45s tempermental when it comes to OAL? The other thing that has me thinking is the gun oversprung. I have no idea whats in it, whatever the gunsmith put in it, its heavy so Im assuming a factory weight one. What would a good weight be for a .45 at 170 pf? Im having the same issue with my loads using 200 gr swc's. Any input is appreciated. My dad left me this gun when he passed away and Ive shot it very little. Thanks! Link to comment Share on other sites More sharing options...
Aircooled6racer Posted October 23, 2016 Share Posted October 23, 2016 Hello: Try a 14lb recoil spring and see if your feeding problem goes away. I load my 45acp to 1.235 for semi wad cutters and round nose etc. Thanks, Eric Link to comment Share on other sites More sharing options...
earplug Posted October 23, 2016 Share Posted October 23, 2016 Its possible that your extractor is not controlling the round as it feeds from the magazine. Do some research on how it interacts with feeding. Link to comment Share on other sites More sharing options...
Jody Waring Posted October 23, 2016 Author Share Posted October 23, 2016 Eric thanks I happen to have a new 14 lb spring, I'll try it. As far as the extractor goes manually cycling the gun it feeds and chambers so smooth you would literally think the gun is empty. I'll try the spring first and go from there. Thanks guys.

js1130146 Posted October 24, 2016 Share Posted October 24, 2016 My SS load is about 170-172 pf with a 230 grain rn at 1.24. I also use a 14lb spring. Link to comment Share on other sites More sharing options...
GunBugBit Posted November 2, 2016 Share Posted November 2, 2016 There's a chance your chamber throat edge -- the edge the round must pivot over in order to enter the chamber -- needs a slight radius and polish. A sharp edge, which many 1911s have from the factory, isn't optimal for feeding some types of bullets. If you know how to do this, do it, but if overdone it can remove critical chamber support.

tngunnut69 Posted November 10, 2016 Share Posted November 10, 2016 Try Different magazines. It sounds as though the feed lips may be a little long and are not releasing the rear of the cartridge early enough for it to chamber properly. The length and/or shape of the feed lips (tapered, flared, etc.) will make a difference depending on what bullet you are running. Try RN bullets and see if that is different.

Jody Waring Posted November 11, 2016 Author Share Posted November 11, 2016 The mags are shooting star ones. What dimensions should they have? Link to comment Share on other sites More sharing options...
DagoRed Posted November 11, 2016 Share Posted November 11, 2016 Easiest test is buy a box of factory 230g ammo, if it all cycles fine through you're looking at ammo. when I first started shooting SWC I had a bunch of issues too. My shoulder was even w case mouth because two loading manuals I had the COL ended up w them there. Another competitor uses same bullet type and gave me a few of his to get my seating depth right, issues disappeared. 2000+ rounds through since then w no issue. I'd suspect the 230 TC try a 200swc you can get the shoulder a little further out Mags would be my second test. With good mags I haven't had an issue. (Shooting star, power mags, 47d. I prefer the chip overall) Cheap rock island factory mag I had w one gun sucked and gave issues. It's a paperweight now Red Link to comment Share on other sites More sharing options...
texasref Posted November 18, 2016 Share Posted November 18, 2016 I have a Ruger SR1911 commander. Will not feed TC or HP rounds reliably. The 45 1911 is a 230gn RN gun. It's been my experience that's just what it wants. Factory or reloaded. You also mentioned a 14# recoil spring but nothing about the hammer or mainspring being replaced. I run a 14# recoil in mine but I also replaced the mainspring with a 17#. It might help the timing of the cycle a little bit. Link to comment Share on other sites More sharing options...
RayUSPSA81 Posted November 19, 2016 Share Posted November 19, 2016 I would stick with RN bullets and add an aftec extractor of try tuning your extractor. Link to comment Share on other sites More sharing options...
RayUSPSA81 Posted November 19, 2016 Share Posted November 19, 2016 Also would run a 14lb recoil spring. That perfect in my gun to not dip after recoil and feed reliably. Link to comment Share on other sites More sharing options...
