Stymie12000 Posted June 15, 2018 Share Posted June 15, 2018 Just looking for what you guys are getting for group size. Say 20 yards with a frame mounted optic open! I've got a slide mounted optic open and a frame mounted optic open. And the frame isn't as accurate. Just want to make sure something else isn't going on!

Hi-Power Jack Posted June 15, 2018 Share Posted June 15, 2018 I got a 3" group, 10 - shots, at 55 yards with my TruBor. And, 7 of the 10 shots were within 2" Are you shooting a steel gun, or a plastic gun ? Link to comment Share on other sites More sharing options...
Stymie12000 Posted June 15, 2018 Author Share Posted June 15, 2018 (edited) Steel gun with steel grip. With My slide mounted open (steel frame with polumer grip) I can do cloverleaf at 20 yards. Same load is maybe 3"@ 20 with frame mounted I switched optics with same results! Edited June 15, 2018 by Stymie12000 Link to comment Share on other sites More sharing options...
chevrofreak Posted June 16, 2018 Share Posted June 16, 2018 1" or so at 25 yards with my CK, which is frame mounted. Link to comment Share on other sites More sharing options...
mro111lland Posted June 16, 2018 Share Posted June 16, 2018 Sounds like a loose mount or dot I can get 1 inch or less at that distance Link to comment Share on other sites More sharing options...

I did swapp out the optics to rule that out. Also, made sure mount was torqued. That totally crossed my mind. I think something else is going on. Sounds like what Im getting is not the norm. Im going to explore different bullets. Need to rule that out. I have tried hs6 and aa #7. #7 is more accurate in both guns.

Flatland Shooter Posted June 16, 2018 Share Posted June 16, 2018 What bullet are you loading? I have two open guns (both STI framed 2011) and each is very accurate out to 30 yards with the ammo they like and its different for each of them. Both shoot under 3" for 10 shot groups. One likes 125 gr MG and Zero JHP over N-350 and HS-6. The other shoots better with 115 gr MG JHP over N-350. Other loads can give acceptable accuracy but the listed loads are just more accurate.

superdude Posted June 16, 2018 Share Posted June 16, 2018 Ammo can make a huge difference in accuracy. Let us know what you're shooting. Link to comment Share on other sites More sharing options...
Stymie12000 Posted June 16, 2018 Author Share Posted June 16, 2018 (edited) So far I've tried 115gr blue with hs6 and #7. I have also tried 124 fmj with hs6. The 124 shot the worst but I only tried one powder charge. The #7 is by far more accurate in the frame mounted. The slide mounted gun likes both hs6 and #7. I have some 115 fmj MG coming. I'm thinking the one gun may not like the coated. Btw both guns have identical barrels from the same manufacturer!

Flatland Shooter Posted June 16, 2018 Share Posted June 16, 2018 Early on with the first 9x19 open gun I also tried FMJ bullets and the JHP bullets were more accurate. Link to comment Share on other sites More sharing options...
rishii Posted June 16, 2018 Share Posted June 16, 2018 How tight is your slide to frame fit with the frame mounted optic one reason accurails became popular was because with a frame mounted optic you’re aiming the gun with the frame instead of the sights on the slide Link to comment Share on other sites More sharing options...
zzt Posted June 16, 2018 Share Posted June 16, 2018 My Open gun shoot same hole groups at 15 yards with Rainier plated. I get one hole groups with Montana Gold JHP and X-Treme plated. One brand of poly coated bullet is as good as the X-Treme. All of the others I've tried are worse. Link to comment Share on other sites More sharing options...
Stymie12000 Posted June 17, 2018 Author Share Posted June 17, 2018 I should have the MG jhp this week. I'll post how those perform once I get some loaded up! Link to comment Share on other sites More sharing options...

Stymie12000 Posted June 18, 2018 Author Share Posted June 18, 2018 115. I also have silhouette, hs6, #7, and 3n38. To test with. But I'll keep it simple at first and go with #7. Link to comment Share on other sites More sharing options...
SilverBolt Posted June 18, 2018 Share Posted June 18, 2018 Do both guns run the same barrel? Link to comment Share on other sites More sharing options...
troupe Posted June 18, 2018 Share Posted June 18, 2018 My last open gun from Don Fraley, shooting Win 540 that I had 8lbs of and Montana Gold 115 round nose complete jacketed shot 1.5 at 50. The gun liked the ammo and and AWT builds very accurate pistols. Link to comment Share on other sites More sharing options...

I even switched the barrel/slide from one to the other. Lockup wasn't great but accuracy was better! Lockup is really tight with the barrel/slide that it was fit with!

Knguyen1904 Posted June 19, 2018 Share Posted June 19, 2018 I can get cloverleafs at that distance if I do my part. I’m running a 5” infinity ultimatch barrel and deltapoint pro on a Everglades Mount . Ammo is 8.5gn HS-6 w/115 gn Precision Delta JHP 1.165” at 172 PF Link to comment Share on other sites More sharing options...
johnsonian85 Posted June 19, 2018 Share Posted June 19, 2018 Are your bullets hitting the comp? When I picked up my open gun (used) I had to ream the comp and then everything tightened up. (Everglades 124 JHP, HS-6, never used anything else.) Link to comment Share on other sites More sharing options...

I have tried the everglades 124 and hs6. That gave me the worst accuracy. However my everglades bullets mic out at .3535". So I'm going to slug the bore. See if it's on loose side!

Stymie12000 Posted June 20, 2018 Author Share Posted June 20, 2018 Slugged both barrels. Both were the same. However in the process I noticed what looks to be baffle strikes. Even though I ran a comp reamer. For some reason I may still be getting strikes. I'm going to put the barrel.in the lathe today and run some #. For some reason, maybe the comp is not running true to the bore! Link to comment Share on other sites More sharing options...
Stymie12000 Posted June 20, 2018 Author Share Posted June 20, 2018 Got the barrel on the lathe. Indicated in the barrel true. Sure enough the comp was .005" out round with the bore. So I opened the comp up to .375 to get the comp concentric with the bore. Now to go test! Link to comment Share on other sites More sharing options...

I've found the comp reamers to not reliably relieve baffle strikes. I ream to 0.375" now and go. Link to comment Share on other sites More sharing options...
