bulge the barrel... well it was either setback or I squibbed and didn't know it. I know its kinda hard to overcharge 9 major. I used 8.5g HS6 and it pretty much fills it. I would thin a squib would be catastrophic and being an RO for some time I usually pick up on that. It felt like a smack to my palm, that's about it. You are right on reloading technique, though I have been doing it for years and done 1,000's for this gun and others - it only takes one!

First mishap with any of my guns - bulged the barrel on my STI GrandMaster 9mm with the two port T1 comp trubor. Would I replace this with the same barrel or go with the T2 comp with 3 ports? Forget STI and go with a Schumann or something else?

I'm pretty happy with the RMR 124 HPs, they look strange loaded all the way out vs a conical HP, but for the price they are great and the accuracy is good too.

9# 9mm major STI Grandmaster Trubor

I'm using xtreme hollow point which are heavy plated in my STI GrandMaster 9mm open gun and they work really well. Not as good as JHPs but for 7 cents (on sale) each I bought 4,000. Load them just like the JHPs

I dunno, I'm using 26.2 of 748 26.0 got me and average of 2817 with mixed brass with a 16" 1-7 barrel

+1 RMR

+1 skateboard tape with skulls!

I am a lefty and like the RHT. I had to shave it a bit to fit flush to the frame on the right hand side and fits over the slide release bar or whatever its called... but yes, had to drill the frame. Adding one to my limited gun.

I've loaded about 5000 and shot 2000 so far in 9mm major. I have loaded them at 1.135 minor in the gen 3 G34. We had a match with long distance targets and they were accurate in 9 major.

I'll have to try the 8# - no slide battery going on?

I could not find SP so found SPMs at a good deal - they run 100%

not surprising. I have a GrandMaster Trubor that takes 8.4-8.5 with a 124 @ 175-177

Have the GrandMaster in 9 major. Using a standard SS guide rod with 9lb spring. Have and 8 I have not tried yet. 9 seems good.

it looks like the round is not pointing at the breach, just below it so most impact the upper part of the ramp on the way in. Is that mag catch? It appears that even with that situation the mags are running ok - at least with me manually racking the rounds with each full magazine.

I've been reloading RMR JHPs and they have a rounded nose profile...

Hi, I load RMR 124s (they are actually 125 on my scale). OAL is 1.168 and I use for my gun (STI GrandMaster Trubor) 8.4g of HS-6. I'm getting ~175 pf out of it but my gun appears to be slow (like the owner). Plenty of grip on the bullet but they do look different because they are much rounder than PDs or MGs.

ok, so tuning the mags - rear feed lip at .350 and front at .360 - still hit the feed ramp pretty solid. Opened it up to .370 and now bullet points right at the breach or just hit top of feed ramp. Going by Atlas recommendations was .350x.360 but you should check to see that the bullet points at the breech. Go figure, I'll see with some live fire and next match.

Hello all, Boy I wish my eyes were still good and I could still shoot limited with a 100% gun and mags. Anyway, have an STI GrandMaster Trubor in 9mm major. My load is 124g JHP @ 1.168 with 8.4 HS-6 which runs ~175pf and gun operates the load with no issue. I have fits with the magazines. They are 2 old style STI 140mm, 1 old style STI 170mm (28 rnds), and 1 new style STI 9mm/38 super (29 rnds). They ran good for a short period of time and now its almost every stage they hiccup. It appears to be primarily nose-dives. I put Hardy spacers in them, actually had to in the "new" STI to get it to run right. They all have Grams guts with Dawson basepads. I am going through each one with a tuning kit and replacing all the mag springs even though they are about 4mos old. I do shoot a lot. I have heard all kinds of advice including dump them and go MBX. I'd rather not and giving it one last try. I have done searches and though informative, don't really give good advice as it seems more opinion. So, tuning all feed lips .350-.355 in front to .005-.010 to back, replacing springs, keeping spacers (should these be glued?). Recoil spring is 9lbs and about 3mos old - gun shoot pretty flat. Like I said if this doesn't work I'll be buying MBXs because I have enough problems shooting on my own without Gffing every other stage. Thanks!

maybe try 1.135?

saw Atlanta Arms majors last night - sparks and flames! -gotta get some

do it because its a hobby
