  1. You can't directly. That only works if you are fortunate enough to get a barrel with an extension that is an interference fit in your upper... I know of 2 things you can do in this case. 1 is to insert a shim to take up the space. The other is to use loctite bearing retaining compound (its green but I don't recall the number) I have used the loctite method and it's helped in some cases. This topic has come up before if you do a search you'll find some stuff.
  2. In my case pro no they won't. But if you size them in your sizing die after you rollsize them they should drop in.
  3. I read True Grit years ago after running across it in a used book shop. I hadn't thought of it in a while. I think I may have to see if I can find some of his other stuff and give it a read. Thanks for the reminder.
  4. My favorite is still a 1911 barrel link shaved on the back side to clear the grip.
  5. You might try Ed Vandenberg he'd likely build you anything you'd want. http://www.vandenbergcustom.com/pistols
  6. Probably if you stay with powders that are the right burn rates for that gas system and bullets with a similar profile and weight to what's supposed to be used you can avoid bending an op rod. Might go check over on the cmp forums for some ideas.
  7. Look at where the ribs are at the front of an original sti style mag and think about where a 9mm round hits those vs where a 38sc hits them, that's part of it. Sv or mbx or new sti with a single longer rib doesn't require it (though I still use spacers in my sv mags to keep everything the same. I think it also helps to get the nose of the bullet closer to where it should be with respect to the feed ramp for better feeding but that's probably secondary.
  8. I shot the nationals in Missoula (05 or 06?) I thought they did a good job probably I'd be interested if it ever went back there.
  9. Yep i seem to recall one nationals there was referred to as the Mud Bowl
  10. Thanks for sharing it. I like to chrono every shot during load development, and having the thing hanging on the barrel always stopped me from going down this path. It's a neat solution to the problem I'll have to build something similar.
  11. Be curious about details on your rail mount adapter.

    Romeo 1 Pro

    Yep bought several high end scopes from them... Always been good to do business with.
  13. Give this a look... some interesting analysis around port sizing and spacing. I seem to recall he's done some other simulations (which I can't seem to find right now.)

    9 Major

    Yes 9mm major will work with a normal upright cmore mount. The easiest approach is change the barrel and see where you are. Then if you are having issues. Try following this http://www.brazoscustom.com/magart/ejection perfection.htm Brazos custom sells an ejector that's already tuned as described if you don't want to do it yourself. I prefer an aftec for an extractor but opinions on that vary. A normal extractor can be made to work just as well with tuning. I find using once fired, single headstamp brass (not hard to get or terribly expensive) makes the tuning process easier but commercial headstamp range brass can usually be made to work in most guns.
  15. I'm like zzt above I like 2 3/16th holes and a good effective 3 port comp with a powder that works the comp/ports and makes major (in my case silhouette)
  16. Mini red dots do make it easier, but truthfully it wasn't that hard to get it to work with a full sized cmore if you understand how to tune the extractor and ejector.
  17. Tom were those factory 40x repeater actions or converted single shot actions. I ask as i have a vintage 40x smallbore gun that might interest me more as a repeater.
  18. I've shot silhouette for years... Works fine for me.
  19. Yep i picked up a couple as well... will be interested to look them over and take some measurements. Given their reputation I expect good things.
  20. I think you are on to something Eric.
  21. Ehh the shorter the barrel the more likely you are to notice a benefit i guess. Probably running a medium or slower burn rate powder all other things equal would run the brake better. But if it was me I wouldn't spend big money on a pcc brake I think it's better to mess with tuning the springs and buffer setup for a blowback gun. But in the end only you and the timer know what works best for you.
  22. Yep that was pretty much my point.. it helps people understand the difference in magnitude of the forces at work.between the gas from a major load in a 5" barrel and the gas from a minor load in a 16" barrel.
  23. If you want a calibrating comparison try the same test on the comp of an open pistol running major.
