thatgrittyguy Posted April 14, 2014 Share Posted April 14, 2014 Ladies and gents, I've been lurking around, but not talking much. It's about time I post something. I'm working on an open gun for shooting steel challenge. Here's my setup thus far: G34 Lone wolf threaded barrel Carver 3 port comp 11 lb ISMI flat spring Dawson ICE magwell Sevigny Competition sights Glockworx trigger spring kit My reloads are : 146 Power factor 5.3gr of HP-38 / W231 1.153" COAL 115gr Berry's plated CCI primers I've got a few issues and would love some feedback. 1) The comp doesn't seem to be much benefit. The gun loses reliability around the 125 power factor range,so I like to keep it above 130. Should I step up/down the power factor of my current reloads? Different comp? I'd love to get some autocomp powder, but it's not around in my area. 2) Red dot options. I like the look of smaller, reflex style sights that are milled into the slide. Delta point, RMR, FastFired, etc... Is anyone using those in competition though? Seems like it's all C-More. Any concerns with having the sight on the slide, or is it not a significant factor? I would expect fixing it to the frame would make the dot easier to track, but I don't really have first hand experience yet. Anyone have a favorite frame mount to recommend? Any advice on this would be very helpful. Help me Obi-wan Kenobi. You're my only hope. Link to comment Share on other sites More sharing options...
Mad Doc Posted April 14, 2014 Share Posted April 14, 2014 I've tried the RMR, J point and delta point. The Leupold delta point is by far the best unless you are going into combat then the RMR is probably better. Link to comment Share on other sites More sharing options...
Kraj Posted April 14, 2014 Share Posted April 14, 2014 Are you going to always shoot minor? I just started shooting open with a G17 this season but its my understanding that the more gas to work the comp the better. Im pushing 115gn bullets to 1500ish fps. When i was building it and shot it with just the comp and no dot it was really clear that the comp helped keep it flat. Is the powder your using a good match for open?

thatgrittyguy Posted April 14, 2014 Author Share Posted April 14, 2014 Kraj, I'm not opposed to shooting major. What comp and powder were you using? Link to comment Share on other sites More sharing options...
ajjacks916 Posted April 19, 2014 Share Posted April 19, 2014 125gr Ibejiheads with 7gr of AutoComp is a great combo. Link to comment Share on other sites More sharing options...
Kraj Posted June 11, 2014 Share Posted June 11, 2014 I'm using 115 gn MG bullets with 7.5gn of Autocomp. It makes 175 power factor and works well with my 5 port sjc comp. Link to comment Share on other sites More sharing options...
Hockey03 Posted June 11, 2014 Share Posted June 11, 2014 I have a delta point milled on the slide and a cmore on a mount . the cmore on a mount is much easier to track. Link to comment Share on other sites More sharing options...
kneelingatlas Posted June 11, 2014 Share Posted June 11, 2014 If you want to shoot minor you'll need the lightest spring which will strip the next round out of the mag. The comp adds weight to the barrel as well as keeping the action locked up longer, dissipating more energy which would be used to cycle the slide. Unfortunately powder is still hard to get and the comp will have very little effect until you get a slow powder up around 150PF. Open minor is tough because you need gas to work the comp. The best way to do it would be to use a case full of powder which is a little too slow to make major like Longshot or N105. The other way to go with Open steel is to remove the comp and shoot mouse farts with a dot. I load 3gr of Clays under 115s for a PF under 100, an 8# recoil spring and the light bullets keep the action moving fast, but it's very soft; the dot just bounces from one piece of steel to the next Now if you want to shoot Major with your Glock you'll want to find one of a select group of powders: HS6, Autocomp, Silhouette, 3n38.

DRichardson Posted June 11, 2014 Share Posted June 11, 2014 Kneeling, are you loading relatively short for 9 major? I haven't had any problem making major in 9mm with longshot. Granted there is a relatively narrow window because it really doesn't like to be compressed but it will work, and works well for me. Just some extra data.

kneelingatlas Posted June 11, 2014 Share Posted June 11, 2014 Kneeling, are you loading relatively short for 9 major? Yes, I shoot mostly small frame CZ and Tanfoglio Open guns, so the max is ~1.165"; once I get my large frame Tanfo up and running I might try some .38 super mags and load some 1.2"+ I really only played around a little with Longshot because I had a friend who needed WST so I traded for a pound. I have a bunch of SP2 and HS6 which works really well @ 1.15". Link to comment Share on other sites More sharing options...
Zaldy Posted October 3, 2014 Share Posted October 3, 2014 125gr Ibejiheads with 7gr of AutoComp is a great combo. What Pistol and OAL? i am thinking of 125 ibeji 6gr AutoComp @ 1.145 OAL for Glock22 40-9mm Link to comment Share on other sites More sharing options...
