The CZ's I've had have had short freebore, so that "straight" bullets like the XTP needed to be seated much deeper than when shot in something like a Glock or BHP. Other bullets like Gold Dots or West Coast PRN could be seated out to 1.150" no problems.

You're just jealous 'cause you don't have a dryfire laser.

I just the flexible Glock cleaning rod with a large patch rolled through/around it, and snake it in from the port or from underneath. I do the same for my bolt gun.

200gr plated RN 5.1gr Titegroup 1.260" nominal OAL 8000+ and counting in my 1911...

I had this same problem with one of my CZ's. Not wanting to mess with it, I sent it back to CZ-USA. He claims to have replaced the slidelock lever spring, and it works OK now.

On a silhouette, hits were barely perceptible with XM193 at 500 yards. Switching to 75gr made it easier to observe. Switching again to 110gr 6.8SPC was much easier. FWIW, I shoot 75gr on far stuff because it shoots great in my gun and hits the steel a little harder (which makes spotting hits faster), and then switch over to XM193 for 100 and in. -z

VV-3N37 can drive a 90gr Gold Dot to over 1600fps in 9x19 in a standard pistol like a CZ or Glock.
-
If I remember correctly, Winchester white box 124gr "NATO" shoots just over 1100fps in my pistols, while Speer Gold Dot +P 124gr shoots about 1310. Pressure != velocity, I know... SAAMI spec is 35,000psi. -z

The most common answer for long range is the 175SMK since it can be fired at a decent velocity (2700fps from 24"'s). There are other lighter bullets with nearly as good or better BC's that may work better at long range: _Bullet_ _BC_ _MV_ 0 200 400 600 800 1000 | YARDS 190 SMK 0.53* 2560 > -0.00 0.00 6.22 14.17 24.10 36.54 | drop (moa) 175 SMK 0.51* 2675 > -0.00 0.00 5.75 13.22 22.67 34.70 | drop (moa) 155 Scenar 0.508 2850 > -0.00 0.00 4.94 11.32 19.30 29.33 | drop (moa) 190 SMK 0.53* 2560 > 0.00 2.81 12.05 29.21 56.01 94.16 | wind (inches) 175 SMK 0.51* 2675 > 0.00 2.85 12.23 29.69 57.25 96.76 | wind (inches) 155 Scenar 0.508 2850 > 0.00 2.53 10.83 26.17 50.19 84.66 | wind (inches) 190 SMK 0.53* 2560 > 2560 2244 1949 1678 1437 1237 | velocity (fps) 175 SMK 0.51* 2675 > 2675 2328 2007 1713 1452 1238 | velocity (fps) 155 Scenar 0.508 2850 > 2850 2498 2171 1871 1600 1366 | velocity (fps) I just guessed at the 190gr velocity, but the 175 and 155 loads are still moderate. -z

For whatever accuracy you want (under 1.5MOA), it's going to be cheaper to build an AR10 that does it vs. an M1A. And mounting optics on the AR10 is a lot cleaner. I think you'd want a 24" barrel. Loads from my 20" AR10 seem to lose their legs after about 600 yards. Not sure how 22" works. I find spotting hits much easier from a bolt rifle without a brake vs. my AR10 even with a brake. -z

My Dan Wession Patriot has an external extractor. I broke the first one due to crud building up under it. I stoned the second one's top and bottom surfaces before installing it to ensure there was minimal friction and enough clearance, and it's run 100% since then (8000+ rounds).
-
Major is looking unlikely in anything shorter than a 20". Paul E might have some better data. 1MOA or better is easy to accomplish, though. Lots of load data is available, on my web page, Hodgdon & IMR, March/April Rifle Shooter magazine, etc. -z

Looking For Comments On My Pending All Around Ar
Zak Smith replied to GrimReaper's topic in Rifle - Technical
If you want to shoot CMP, you need something CMP legal. You're also on a budget. And you want to shoot some 3Gun. Note that flat-top receivers are now legal for High Power, but not necessarily optimal for the longest distance (not enough elevation travel in the clamp-on carry handle A2 sights). For CMP legality, it must resemble an A2 or A4 comfiguration rifle. Suggestion: Buy a standard A4 configuration from Rock River, with a stainess 1:8" twist barrel (+$65), A2 handguards. The RRA NM trigger is already included. http://www.rockriverarms.com/item-detail.c...36;A1$283g Use a clamp-on A2-style rear sight (now legal) and use the flash hider or a bare muzzle for CMP. For 3Gun, you could shoot it as is, or get a muzzle compensator and put on an optic. Staying with iron sights would leave you in Limited class, and putting an optic on would put you in Modified/Tactical class. It's certainly not optimized for either sport, but it'll be a great all around rifle. -z -
It's an issue with the spring compression vs. the spring retaining shoulder on the pin vs. the ITS. If I just drop the FP in there with no spring, it protrudes real far past the breechface. With the spring in place, it can't compress enough to clear the FP stop.
-
FWIW, I have the same problem with mv SV, but the failure rate is lower now. I did replace the mainspring with a regular 1911 "stock" power one. I did get a extended firing pin from ShootersConnection or SpeedShooters or somewhere a while back, but i would not fit due the SV interchangable breech face.

Larue SPR mount.

I've got a GAP rifle on a McBros action. Skip the magazine, save the money and just get a single shot. It's not practical because latching a mag into place takes a whole bunch of fiddling to get seated correctly. Look at the TAC50 stock. The sporter style leaves a lot to be desired as far as cheek weld goes. I sugget a more effective brake than the McMillan style narrow one. Other than that, it's great. -z
-
Yes. I assume these were ones TP had in stock but couldn't sell until the AI situation was resolved.
-
Try on SnipersHide, SnipersParadise, and here, for match announcements.
-
Then I don't know what those mags that showed up were...
-
I think you mixed up M1 vs M3 in your post. A good compromise might be 0.1 mil clicks.
-
I've also spoken to Alice @ TacPro. They're back in the business of shipping AI stuff as of this past Monday.

I just saw this announced: Cavalry Arms Competition Shooters Program http://www.ar15.com/forums/topic.html?b=2&...t=146635&page=1
