[CZ's have slow barrels?]

The CZ barrels have a 1/16.

I thought CZs have 1/10?

[Barrel Twist Rate vs Bullet Size]

Do 147, 124 and 115gr bullets shoot better out of barrels with certain twist rates?

[Practicing Classifiers]

Do most GMs and Ms practice classifiers to help get their ranking?

[Strongmount - 650 vs 550/650]

Looks like there is a Strongmount made for the 650 (6.5") and one made for the 550/650 (8.5")

For the XL 650, is one better than the other?

[CZ's have slow barrels?]

My Glock 17 (4.5") gets about 5 PF less than my Glock 34 (5.3") with the same load.

[CZ's have slow barrels?]

How long is your M&P barrel? Longer barrel = higher velocity.

[Favorite Lube]

Been having good results with EWL30. Same formula as EWL but in a 30 weight viscosity. Doesn't dry out or run off.

[Longest OAL]

For an SP-01 Shadow with the re-profiled slide stop - what is the longest OAL it can run reliably?

I'm using 147gr Xtreme RN.

[Natural Talent]

I am still trying to understand the point of the question? For a shooter to be interested enough to "Stick with" shooting USPSA matches, enough to shoot once a weekend for years, they would need at least a little bit of a competitive drive. This competitive drive makes people want to perform better so they can be more competitive and beat or contended with their competition. Competitive people are usually drawn to practicing the skills required to compete so they can be more competitive. I think that finding a "Competitive" shooter who is interested enough to attend weekly matches for years on end, who also NEVER practices in any way shape or form would be very hard to find. So once again, what is the point of the initial question? The shooters who would fit into this category are a very, vary small small subset of what could be considered your "Average" shooter.

I don't know how your local clubs are, but the ones around here - you find plenty of "competitive" shooters who just enjoy shooting the local match. They arn't interested in winning or getting better - they just enjoy guns, shooting and the cameraderie. They don't run drills or practice. The match IS their practice.

[Natural Talent]

Let's look at it by the official numbers:

2014 active members = 23,747

GM = 1.5%

M = 5.8%

A = 10.6%

B = 24.8%
C = 40.9%

D = 16.5%

Most shooters = C + B = 65.7% of the classified membership.

65.7% = 15,601 of which 62.3% are C shooters and 37.7% are B shooters.

Now take out those that do drills, practice and dry fire - and only take shooters that shoot matches once a week max.

What is the best they are going to rank?

My guess would be C.

[Natural Talent]

GM.

If you truly have 'natural talent' no practice is required.....or maybe a definition of natural talent is required.

I meant your average shooter, average natural talent, not practicing and only shooting matches once a week max.

[Natural Talent]

what do you mean by 'shooting matches'? do you mean shooting 1 match every month? or do you mean shooting a uspsa match every saturday with top shooters, doing the match again with a 2nd gun, and shooting steel challenge every tuesday and thursday?

The real question is 'who cares?'

I was talking about 1 match per week max.

And if you don't care, why are you posting in this thread?

[Natural Talent]

What is the highest classification do you think most shooters can attain by natural talent and shooting matches alone? No practice, drills or dry fire.

[9 mm reloading - Which Crimp die?]

I have had very good results with my 550b and Lee dies. I recently switched to the EGW U-die (made by Lee) and that in combination with the FCD, yields 99/100 rounds passing my EGW case gauge using mixed headstamps.

[SRTS vs Pre-B Disconnector]

I realize that the CZC Short Reset Trigger System ($135) is hand-fitted, but how much shorter is the reset in SA compared to the Pre-B Disconnector?

[550 loaders how often do you check your powder charge?]

Since I changed to the Uniquetek micrometer bar I do like you do then just load away. I look at the indexing on it periodically to see if it has turned but it never does.

Yes, it was a very good investment and keeps the charges consistent.

[CGW Disco vs. Pre-B Disco]

Thanks. So single action pre-travel is about the same?

[CGW Disco vs. Pre-B Disco]

Is there any difference in the single action pre-travel, between the Pre-B disconnector from CZC and the CGW type-1 disco?

[Crimp vs. Accuracy]

Some interesting data:

AAA 147gr crimp = .376 (measured different head-stamps)

Win White Box 115gr crimp = .375

Fed Champion 115gr crimp = .375

[Crimp vs. Accuracy]

TaperCrimp = (( Case Wall Thickness x 2 ) + Bullet Diamater) - .003

No matter what I’ve tried thus far, the accuracy is not what I was hoping for at 25 yards. I have to believe there is another force at play here. This thread almost confirms that, but I still don’t know what to do about it…..

Interesting formula. Anyone have a ransom rest and some free time to test different crimp measurements?

[Crimp vs. Accuracy]

Saami specs are .380 to .381 for 9mm

[Crimp vs. Accuracy]

So WIN=.383 and FC=.380?

Would .383 pass the case gauge?

[Crimp vs. Accuracy]

It all depends on brass, bullets, etc. I'm loading RP brass and I'm only able to get .379 crimp. If you measure your case wall thickness and bullet diameter with calipers simple math will tell you what your crimp needs to be for that bullet and case.

I'm getting .0135 for WIN brass and .012 for FC brass. I use Xtreme 147gr plated, which are .356

So WIN=.383 and FC=.380?

[9 mm reloading - Which Crimp die?]

I love the Udie but I did so much reading about how the regular LEE die was plenty small (tight) to prevent set back. So I got one and tried it. But I'm currently loading RP brass which has nice thick case walls. Everything is tight as a drum. Like I originally said, I got the Udie because I was getting set back with my Dillon die. But I narrowed it down to FC and Blazer brass as having really thin case walls. I never used it to make sure ammo would chamber. Everything I loaded chambered fine, even the loads where the bullet would push into the case after loaded. The Udie works really well at what it's designed to do and I will still use it on problematic brass as needed. I will do a test shortly and see if the standard LEE works well on FC and other thin case walled brass. If it does, for my purposes, there is really no need to work the brass so hard with the udie. Hope all of that made sense!

Yes, makes sense. It will be interesting to see what you find with the Standard Lee and thin walled cases.

[Crimp vs. Accuracy]

Have you found too much crimp effects accuracy?

I have been crimping to .377 - What measurement do you find gives the best accuracy in 9mm?
