rod m1 Posted April 22, 2006 Share Posted April 22, 2006 I'm presently using an 18lb spring and would like to try using a 10lb spring. How can I estimate a safe starting load for a light spring? Components I use for 45ACP LSWC 200 grain Titgroup 5.0 or Clays 3.6 Winchester primers Link to comment Share on other sites More sharing options...
Loves2Shoot Posted April 22, 2006 Share Posted April 22, 2006 Heavy bullets and light springs aren't the best combo for reliable feeding IMO. If you have a burning itch to use a 10 lb. spring you might consder a lighter bullet. Link to comment Share on other sites More sharing options...
Flyin40 Posted April 22, 2006 Share Posted April 22, 2006 Not sure how it would run with a 10lb spring. I run a 8lb now and going back to a 10lb spring for an open gun with a lightened slide. Flyin40 Link to comment Share on other sites More sharing options...
rod m1 Posted April 22, 2006 Author Share Posted April 22, 2006 I should add this is a stock full size Colt. What I wont to do is shoot light target loads to help reduce recoil and hopefully helps stop flinching. It sounds like if I pick a load in the miner power factor range that would be what I wont. But I don't really now where or how to start this. Link to comment Share on other sites More sharing options...
yoshidaex Posted April 22, 2006 Share Posted April 22, 2006 10 lbs spring with the following load out of my kimber 45 acp 200 grn berry's PSWC 4.2 - 4.3 Titegroup 1.23 OAL Federal Primers Mouse fart load..... Bumping the powder up to 5.1 - 5.2 gets me into the 165+ PF. Feeds, extracts and fires fine with the 10 lbs spring. I do use a shock buff at this point though Link to comment Share on other sites More sharing options...

How can I estimate a safe starting load for a light spring?Components I use for 45ACP LSWC 200 grain Titgroup 5.0 or Clays 3.6 Winchester primers I use a 14# spring in my TGO1 and PC1911 4.1 Tightgroup (168pf) and 230 ball or 4.4 Tightgroup (168pf) and 200 LSWC 4.1 Clays (168pf) and 230 ball I prefer and love the feel of the 12# springs, the gun cycled great and recoil was non existant, but I was replacing chewed up recoil buffer pieces after every second match. I think with the load you're talking about (5.0 tightgroup) combined with a 10# spring might be a little too harsh on the gun. Link to comment Share on other sites More sharing options...
JD45 Posted April 25, 2006 Share Posted April 25, 2006 Try a CP buff. I'll bet a hundred spent primers they will last 1000rds. in your gun. Link to comment Share on other sites More sharing options...
