762rocstarr Posted September 9, 2014 Share Posted September 9, 2014 What are you running for spring weights and why? I'm trying to dial in 3 different 1911's chambered in .45acp. What type of problems will encounter with light recoil spring weights? Link to comment Share on other sites More sharing options...
blaese490 Posted September 10, 2014 Share Posted September 10, 2014 I'm interested in the same Question. I have a STI Trojan and it runs reloads great... Why would i want to change the springs... what are the advantages... Would i change bases on shooting major or minor loads? Link to comment Share on other sites More sharing options...
Pat Miles Posted September 10, 2014 Share Posted September 10, 2014 (edited) Too light a spring and the gun will beat itself to death. Spring weight depends on the velocity of the ammo you are shooting. The hotter the ammo, the heavier the spring. Generally, a 14# spring is a good choice. If you want to set the gun up for USPSA the video below will give you a good idea how to and why.

Steve RA Posted September 10, 2014 Share Posted September 10, 2014 I run a 17lb mainspring and a 15lb variable rate Wolff recoil spring in my .45. Also with a shock buff and a 1 piece guide rod. Link to comment Share on other sites More sharing options...
762rocstarr Posted September 12, 2014 Author Share Posted September 12, 2014 Thanks for the responses. That video was very helpful! I think I will try an 11 with a buffer. I'm shooting Major 200gr swc and 4.5 grains of V310. Thoughts? Link to comment Share on other sites More sharing options...
Pat Miles Posted September 12, 2014 Share Posted September 12, 2014 If you spring the gun correctly you don't need a shock buff. Just one more thing to cause problems. Some folks spring their guns too light and then use a buff to make up for it. Eventually the buff gets chewed up from the pounding it takes and comes apart causing problems at the wrong time.

I think its going to depend on your barrel. In my gun, that load just barely makes major PF. I have to go to 4.7 gr of N310 to get 170-ish PF. A friend of mine using that same load got 180 PF and had to drop it down to 4.4 grs for 170 PF. For my load I run a 13 lb recoil (no shok-buff) and an 18 lb mainspring.

wheelie Posted September 13, 2014 Share Posted September 13, 2014 That is a lot of VV310 in any barrel. Link to comment Share on other sites More sharing options...
2MoreChains Posted September 14, 2014 Share Posted September 14, 2014 Patrick Sweeney wrote about Bill Wilson's pet load back in the day which IIRC was 4.6 gr N310 and a 200 gr LSWC. Yeah, its over the VV recommended load. Conservative IMO. Link to comment Share on other sites More sharing options...
