10lb Spring In 1911?

[rod m1]

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

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.

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.

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.

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

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.

Try a CP buff. I'll bet a hundred spent primers they will last 1000rds. in your gun.
