Targetpractice Posted March 27, 2016 Share Posted March 27, 2016 Just wondering if anyone here is running a 125gr black bullet international bullet in a compensated 9mm major gun. I ordered some but just heard they may not be good in a compensated pistol for 9mm major. Thoughts? Link to comment Share on other sites More sharing options...
BiggMike Posted March 27, 2016 Share Posted March 27, 2016 I have used them in an open gun and they were good to go. The only reason I am not using them now is my barrel is a tight .355 and the bullets were .356. I had no problem and they were very accurate. They are also very fast bullets in an open gun. When I use up my current lot of MG 124 JHP, I will be switching back to BBI. Link to comment Share on other sites More sharing options...

I have a short barrel so was hoping they would help me make major Link to comment Share on other sites More sharing options...
tcazes Posted March 27, 2016 Share Posted March 27, 2016 Oh they are definitely slick! Just spray a shot of one shot before the match or before a practice session and after cleaning. Helps keep it nice and clean. Otherwise you will love them! The 115's are great too!!! Chandler (guy who owns bbi) also shoots them through his open rig!

tcazes Posted March 28, 2016 Share Posted March 28, 2016 Right sarge! Slightly oversized for a better seal to the rifling, better stabilization while traveling down the bore, better combustion behind it and gas buildup for the comp as well!

Targetpractice Posted March 28, 2016 Author Share Posted March 28, 2016 Ok so I shouldn't have any issues in 9mm major. Especially with the compensator? Link to comment Share on other sites More sharing options...
tcazes Posted March 28, 2016 Share Posted March 28, 2016 Nope. Like I said just a quick shot of case lube before a match or practice session then a quick shot after cleaning and bbis should be fine. Link to comment Share on other sites More sharing options...
tcazes Posted March 28, 2016 Share Posted March 28, 2016 I would however load lower than your current load data and work your way back up. No need to really sling them out there the. Dial back. You might be pleasantly surprised at the velocity difference between them and fmj Link to comment Share on other sites More sharing options...

You might be pleasantly surprised at the velocity difference between them and fmj This is true. I found out when I went from 124gr MG to the BBI 125gr. My 124gr MG load was 7.1gr of Autocomp and was getting a power factor of 174. I tried the same load with the 125gr BBI's and my power factor was close to 180. I lowered my load from 7.1gr to 6.8 of Autocomp for the 125 BBI's and was getting around 174 power factor. Link to comment Share on other sites More sharing options...

tcazes Posted March 28, 2016 Share Posted March 28, 2016 5" t2 trubor barrel will give those results. Not sure what he was shooting though Link to comment Share on other sites More sharing options...
S&W686 Posted March 28, 2016 Share Posted March 28, 2016 (edited) I have a 5" KKM Barrel and Cheely Comp. The gun is from Freedom Gunworks. Edited March 28, 2016 by S&W686 Link to comment Share on other sites More sharing options...

Definitely faster than MG by a whole bunch Link to comment Share on other sites More sharing options...
Sandbagger123 Posted March 28, 2016 Share Posted March 28, 2016 (edited) i just started using them in my new/used open gun. to say they are quick is an understatement. i started at 6.6 AC @ 1.175 and got 1400 FPS = 175 PF. holy smokes. 6.8 got me 1430 FPS. I dropped it to 6.3 and now get 1360= 171 pf. i must have a real fast barrel as reading other post the it should be a bit slower with these loads. I used 125gr to calculate the pf. in reality mine vary from 126 gr to 128 gr so the PF should be higher Edited March 28, 2016 by Sandbagger123 Link to comment Share on other sites More sharing options...

Gonna load them up with either silhouette or autocomp. Leaning towards silhouette though since it burns a little slower. Link to comment Share on other sites More sharing options...
traingq Posted March 30, 2016 Share Posted March 30, 2016 I was loading these to 1.150, but running WAC at 7.2 gr. They did smoke quite a bit and it took a while to clean the gunk out of the comp. Do you think pushing the OAL out a tad bit more and lowering to 6.8 gr of WAC would help fix the smokey-ness and gunk in the comp? The bullets were very accurate and I never had any issues with tumbling out of my STI Matchmaster. I appreciate any info, thanks! Link to comment Share on other sites More sharing options...
tcazes Posted March 30, 2016 Share Posted March 30, 2016 Are you sprayin the comp with a bit of case lube before a match or practice session? If not you should really try that. As for clean up, what's your process? That could actually lead to even more buildup depending on how you are doing it. Link to comment Share on other sites More sharing options...
traingq Posted March 30, 2016 Share Posted March 30, 2016 Thx for the info! No I have not tried that I'll do load up some more rounds of BBI and try that. To clean it is spray the comp with mpro7 and pick out all the build up with a brass pick. The bullets are great! My cmore and cmore blast shield are also gunked up too after shooting. The cmore lens has a coating of either lead or coating of the bullet and so does the blast shield. Am I loading them wrong? Or is it I just have too much powder behind it?

tcazes Posted March 30, 2016 Share Posted March 30, 2016 I'd check my pf over a chrono because you may be loading entirely too hot if it's the same load from your fmj Bullets. It's going to get the cmore dirty so just keep a micro fiber towel handy. You can also try soaking the comp in a white vinegar/rubbing alcohol solution for a little easier cleaning just don't take a Drexel to it!! Other than that powder will play a roll as well so try and shoot some clean powder too. Link to comment Share on other sites More sharing options...
