zzt Posted May 10, 2015 Share Posted May 10, 2015 (edited) Minor or not, I'd recommend a slower powder for a open gun to work the comp a little better. I'd also suggest a lighter bullet. If you have a gun designed for steel challenge, 124gr seems to be the consensus. When I shot 9mm, the only time I used a 147 was if I had to knowck steel down instead of just ringing it.

shootsforfun Posted May 10, 2015 Author Share Posted May 10, 2015 Zzt thanks it's going to be used for 3 gun so steel has to fall. Link to comment Share on other sites More sharing options...
Open1215 Posted May 10, 2015 Share Posted May 10, 2015 Just my 2cents. I think It would need to be a slower powder and light bullet. I'm thinking if you loaded n105 with a 135 and just see what velocity you can get. I'm sure a 135g at a 150pf should work the comp and drop plates? I think you are going to have to experiment a bit and find the sweet spot between bullet, powder, and plates. Plus your guns comp in minor. You may want to load or try a friends who loads major and run a few rounds at major. It may be softer and flatter then a heavy minor load, depending on the gun and comp.

MrPostman Posted May 10, 2015 Share Posted May 10, 2015 Use 115 grain bullets and slow powder to get the most gas out of the load to work the comp. Use this link to Hodgdons online reloading application. http://www.hodgdonreloading.com/data/pistol Link to comment Share on other sites More sharing options...
EkuJustice Posted May 10, 2015 Share Posted May 10, 2015 I would say use lighter bullets and don't try and skimp on power factor just because 3 gun dosent have one. A compensated gun shoots better and flatter with light bullets and a slow powder at a higher PF than it does with a fast powder heavy bullet load. As for anything you know about loads for non compensated guns toss it for compensated guns because it's totally different Link to comment Share on other sites More sharing options...
tagacali Posted June 13, 2015 Share Posted June 13, 2015 I've used my current 124gr that I use for Major load on Minor. I'm using 5.2gr Win AC for minor with 7lbs recoil springs. It works great in steels. Link to comment Share on other sites More sharing options...
Hi-Power Jack Posted June 14, 2015 Share Posted June 14, 2015 Have to agree with Postman and EKU - light bullets, slow powder. What other powders do you have? Link to comment Share on other sites More sharing options...
Tino2212 Posted June 14, 2015 Share Posted June 14, 2015 I just tested a minor load for my open gun with 5.5 grain of n350 and a 115 grain bullet . Super soft shooting minimum dot movement , shot out of a custom 2011 5 inch trubor barrel no holes using a 15 lb mainspring and a 7 lb recoil spring .
