digby7 Posted July 23, 2012 Share Posted July 23, 2012 wondering if anyone has chrono'ed a STI steelmaster in 9mm with factory ammunition and what kind of PF it came out at? If it makes minor - also curious what kind of ammo it is. Getting a steelmaster in a few weeks and thinking about shooting Open Nationals with it in Open Minor. Just curious with the short barrel and all the ports if I need to be buying +p ammo out of it or if something that makes 135 out of a non-comped 5 inch gun is good enough? I dont reload and I shoot 9 minor for everything so being scored as minor even at nationals is not really a concern for me. not making PF is.

msg73 Posted July 24, 2012 Share Posted July 24, 2012 I would think you should make minor pf with factory ammo. The SteelMaster has a 4.15" barrel + the Trubore comp. If you cut off the comp, you'll have a pistol similar to commander length. A commander 1911 would make minor pf with factory ammo, so no reason the SteelMaster won't.

digby7 Posted July 24, 2012 Author Share Posted July 24, 2012 just dont really know how a comp affects velocity or if it doesnt matter so long as theyre not popple holes. so - the velocity of the bullet should be the same as a command length barrel?

Once the bullet leaves the actual barrel, it is going as fast as it ever will. If it makes PF with NO comp, then adding a comp isn't going to slow the bullet down any more than having no comp. Popple holes are different, because they bleed off gas BEFORE the bullet reaches the end of the barrel. Link to comment Share on other sites More sharing options...
digby7 Posted July 24, 2012 Author Share Posted July 24, 2012 ah - ok, that makes alot of sense. now I can stop freaking out about where i'm going to get ammo for this thing. Link to comment Share on other sites More sharing options...
a matt Posted July 24, 2012 Share Posted July 24, 2012 if you are going to the nationals why not get your ammo from someone like atlanta arms and ammo. Im not sure if they do open ammo, but it wont hurt to call or email they. Im just thinking out loud??? Link to comment Share on other sites More sharing options...

Winchester White Box 115gr FMJ is about 136 pf. Winchester 9mm NATO is 141 pf. AFAIK, nobody will load 9mm Major ammo for sale. The liability is too high, and what makes major in my gun might not in yours. Link to comment Share on other sites More sharing options...

So i had a steelmaster earlier this year, sold it and decided i just wanted to focus on iron sights. Six months later I want to shoot open again. So i'm getting another one. The previous gun I had tried some major pf 9mm that my buddy loads and I vaguely remember the gun being much more violent but not much more than that - dont remember if it was a bad violent or just violent and I shoot the same. DC ammo sells Major PF 9mm I believe but i'm so used to shooting 9 minor that i'll just stick with it. If I come in 2nd in open high overall - then next year i'll shoot major until then i'll just go to shoot it and enjoy the experience.

Whoops! Posted July 26, 2012 Share Posted July 26, 2012 In my opinion, the best factory ammo in local stores for minor open is 115 grain Remington UMC. It seems to use one of the slowest burning powders in the 115 grain weight range. Unfortunately, you have to make sure the Remington UMC will make power factor before the match because as stated above, it's on the edge. Link to comment Share on other sites More sharing options...

I believe it wouldn't be a good idea to shoot major out of a steelmaster. It's my understanding the slide it too light to handle it. You could go from a matchmaster to a minor load but not a steelmaster to a major. I could be off buttttttt Link to comment Share on other sites More sharing options...

Probably have run 8k or so rounds of major through it in the past 2 years. My major load is 115 gr FMJ Montana Gold over 8.6 gr Silhouette which makes about 170 PF. Haven't seen any problems. The primers don't even show signs of over pressure. Edited July 29, 2012 by RocketCity1911 Link to comment Share on other sites More sharing options...
msg73 Posted August 3, 2012 Share Posted August 3, 2012 Did you have to change to the heavy recoilmaster spring to shoot major? Link to comment Share on other sites More sharing options...
