  1. Generally there is a fault line that is forcing you to lean - what helps me is using the fault line as a contact point for the leading foot and anchoring it to balance the weight shift. As such, during my walk throughs, I identify exactly where my foot will contact the fault line to set up for a successful lean position.
  2. A few things to consider - plated bullets don't work well at major PF velocities. That doesn't exactly explain your velocity issue but you may have accuracy issues. Did you chrony in low light conditions? If its not the chrony and environment, are you possibly losing powder out of the case? At 6.8 gr of N340, you should have plenty of room in the case but losing powder is one way where you can have inconsistent velocity.
  3. It depends on what you want to run out of it - the best part of a 6" ish range barrel is that you can use your other minor loads, i.e. for production or Carry Optics without changing load data. I had a 5.5" with pinned and weilded shroud by TACCOM 3G which worked fairly well, but in retrospect, I would get something longer around 8". One thing to think about as well is balance - with a full 16" or 14.5" plus yyyuge comp, the rifle is obviously front heavy. 8 + shroud seems to be the sweet spot for balance as well.
  4. I run the Hiperfire Eclipe with the medium return springs and it runs all of these 100%: Winchester Small Rifle Federal Small Rifle Fiochi Small Pistol CCI Small Pistol
  5. There have been volumes written on this so the only thing I'll add is for the extractor, there is a rubber ring that is included with the extractor spring and rubber insert. The one that came from Sig was orange in color; I used that and then when it was time to switch it out, I bought generic parts off Midway for standard AR15s. Keeping this spring fresh, i.e. every few thousand rounds, seemed to help.
  6. I bought a CZ SP-01 Shadow 1 Optics Ready direct from CZC; I found the plates I needed on their website and on BSPS. The system works very well - the plates slide in with a tight fit so just a little bit of filing was required for me. The entire set up has a very good fit and finish; I have a 2.5 SRO on it and it still sits fairly low.
  7. If you're going to spend the money, you might as well go with the R3MAX. The offset isn't really an issue for USPSA applications.
  8. Both have worked in the past - although I have seen a fluke thing where somehow a round got underneath the MBX follower. Regardless of what guts you use, the key is tuning the mag lips with digital calipers and a rubber mallet.
  9. I've used it in multiple setups and it works 100% - its a pretty simple mechanical system so there's not much to go wrong after you get the springs set up for your load. I will say the Blitzkreig with a standard AR15 carbine spring, with a spacer, is what I prefer over the MBX system.
  10. As previously mentioned, to get the timing of the gun right, assuming the metal on metal lock up contact points are not jacked, look at a comination of the recoil/hammer spring. I ran an 8lbs recoil spring with 147 Blues and TG; I ran Fed SPP ( oh what a distant memory when it wasn't a big deal to do that) and took an 11lbs hammer spring and cut 2 coils.
  11. PM9 is an outstanding gun - mine worked well with Chip Mccormick 10 round mags, 147 Blues, and TG. It got a little smokey at FL State for some morning stages but overall a very soft shooting gun and load. Of note, that load was very accurate for coated bullets - 1" at 20 yds. Admittedly I had to try a few different mags before settling on CMs.
  12. The PC Carbine could make an oustanding steel challenge gun in that the recoil system can easily be modified to handle really light loads - it is just one spring and the weights in the bolt can be removed. I bet you can run sub minfor PF easily. TACCOM 3G has a light weight handguard. Another good thing about the Ruger PC is realiability when dirty - this gun runs for days - not finaky with ammo or heavy use at all.
  13. Try the Taylor Freelance - way easier to field strip/clean during a match - just need a hex wrench.
  14. A good buddy got me on Loctite Marine Epoxy and 45/70 grit off Ebay - it works very well on Glocks/Sigs, polymer lowers.
  15. A couple 'gold' standards are Ben Stoeger and Mason Lane; Lane is extremely impressive in that he swipes the mag and seats it in one fluid motion with no apparent change in speed of his hand at any point in the reload. I think the biggest point of performance where most shooters can take a little time off is the initial entry of the mag in the magwell; how much do you slow down, are you orienting the gun so you can see the outside edge of the magwell, etc.
  16. I strongly recommend 10 yards as a rule because crazy things can happen when you shoot steel closer - as previously noted, sometime you have novices that bring out non-standard shot loads and it can end up all over the place, and splash back to the RO/time keeper.
  17. If at all possible, post them - those attending will greatly appreciate the ability to dry fire and train and put their best foot forward when trying to move up in classification.
  18. Whatever you train will feel the most comfortable - for most people, their standard USPSA start position is with their strong hand's corresponding leg slightly to the rear in relation to the other foot. As such, if you are drawing and shooting SHO, most people take a small step forward with that foot while drawing and then engage with the strong hand and strong foot forward. If you have a classified where you have to transition the hand to the support hand, same deal, put that foot forward. Again, many people in USPSA don't dry fire/train SHO - if you put in a few reps each dry fire session, whatever you train will give you success in the rare situations you have to do it for a match.
  19. FWIW - I'm in law enforcement and most engagement are 7 yds and in, and quite a few are in lower light situations; for anything personal defense I would train on night sights; having the dot is good but in high stress situations, you can bring a gun up and not see a dot; it will take you a second to hunt and find it.
  20. While it is certainly possible to run a slide mounted optic in open, it is very rare because it negates a huge advantage that open division affords that CO doesn't - by having the dot frame mounted, most properly set up open guns allow the shooter to keep an eye on the dot and target while the gun is cycling. Arguably you can do this in CO as well but the overall dot movement is less with an open gun, due to both the physics of a major load working the comp, and the fact that the optic is not moving with the slide.
  21. I think the bigger 'hit' is the combined effect of PCC gaining popularity and CO loosing the rules. The net effect is positive because it seems to be bringing more folks in to USPSA.
  22. In situations like this its almost always the comp - even if it is not actually touching the comp, an uneven path through the comp will cause this. It may be worth sending to a gunsmith.
  23. Yes it is way too heavy - its a great backup gun based on simplicity and reliability - for steel challenge, I would definitely run something lighter.
  24. I'm a huge fan of 165 plated for my production load; the dot is definitely slower but as previously stated, your trigger finger won't outrun the gun. For what its worth, the happy medium for me is a 135 Blue or a 138 IBEJ Heads bullet with a medium speed powder , AA2 or N320, pushing 135 PF. I noticed the dot is nearly as fast as faster loads but the felt recoil was significantly lighter.
  25. Tandomkross and MCARBO were a waste of money for me - the TG9 was much better and got the gun to the point where it would keep up with the PCC world, but it is expensive. The Ruger + a TG9 is a great PCC backup gun.
