This is a real pet peeve of mine. You're mixing up your balance sheet and your income statement. When you buy a gun, you convert one asset (cash) into another asset (gun), the difference between what you bought it for and what you could sell it for (depreciation) is the only expense. Ammo and training on the other hand are pure expenses, powder is burned, bullets go downrange and they're spent. If you buy used guns/gear and shop carefully there's a good chance it doesn't cost you anything. So as long as you're not cash poor, switching platforms shouldn't be a huge deal. If you want to do it, do it! Otherwise you'll always be curious. That being said, a lot of shooters talk about switching from Glock to CZ to improve their scores, but that's mostly bullshit, practice improves your scores. I shoot CZs because I'm the CZ guy, if you want to be a CZ guy too, sell the Glocks and get some! I look at diehard Glock guys like the guy at the track with a 1989 LX Mustang who wears his shitty paint job like a badge of honor

Tell us more about this kaboom. 9mm or 40? Powder? Bullet weight?

No, EAA just does a poor job of importing the pistols people want it the calibers they want. For less than the cost of a Limited you could get a 10mm Hunter and re-barrel it in .40, it's the same bottom end with a 6" top end and it makes a pretty great Limited gun:

Tanfoglio Elite pistols utilize polygonal rifling rather than traditional lan and groove rifling so the same rules of thumb don't apply when measuring the diameter of a slug because you're measuring from a point to an opposing flat. My suggestion is to work up a load with 0.355" bullets, then switch to 0.356", drop the charge back 0.4gr, work back to the same PF and compare accuracy.

Oh yes. As a generality, the faster the burn rate the higher the pressure (given the same PF). 3N38 is one of the slowest powders which can be used to make major in 9mm. There's are two loads published my the manufacturer which make major, by contrast the max load for WAC under a 115 makes 134pf (139pf for 124gr).

Just for grins I loaded a handful of Blazer aluminum cases with 9.4gr of SP2 under a 115 Fired cases looked fine, I guess it would've been a better experiment to keep loading them until they split, but I don't have that kind of patience

Not all rounds pushing a 124gr bullet 1,340fps produce the same chamber pressure, after all, what about the Glock 31? 9 major with 3n38 in a stock Glock is probably not a big deal, Autocomp might be another story...

The internals are exactly the same as the Limited, the frame is the standard frame as opposed to the "competition" frame which features more aggressive checkering, a solid hammer pin, and provision for a bolt-on mag well; the Match slide is the same length as the Limited, Limited Pro, or Stock III, but has the standard sight cut with a cheesy adjustable rear sight, blued finish and a straight barrel as opposed to cone fit (the Limited has a cone barrel, Limited Pro and Stock III have straight barrels like the Match). It can make a decent Limited gun, but the resale will be weaker than a Limited; the Hunter is a great value as you get the competition frame for under a grand.

Yes, all my TS triggers have been right around 2lbs right out of the box. The stock hammer leaves a tiny bit of creep, this is my favorite race hammer and makes it very crisp: https://shop.cz-usa.com/productdetail/40108_concealed-hammer-sa-only With a polish job you can get it under 1 1/2lb

In my experience the most valuable QC check is plunk testing each round of your match ammo in the barrel of your pistol. I don't see any value in checking/sorting brass at the beginning of the process. I dry tumble mixed brass (less than an hour), hit it with some case lube, load it, dry tumble again (again less than an hour), kneed it in a clean, dry towel, plunk test each round, placing the pass rounds in an MTM box, run my finger over the head stamps and pull out any stepped cases, and use them in practice. Matches are much more enjoyable when your gun runs 100%

Also, I tumble my loaded rounds to sort out loose primer pockets. My 9 major brass was always in better shape than my 38 super because it never gets loaded more than a few times before I lose it. When I go to a match with mostly reloaders I let them have all the brass, I only pick up brass in my indoor range where most customers are shooting factory ammo, that way my brass is usually in it's second to third loading.

I use mixed range pickup brass to load 9 major without issue, once my ammo boxed are full I just run my finger over the head stamps pulling out stepped brass to be used in practice. IMT, FM, and ammoload all feature a step where the brass sometimes separates.

Nope

If you leave the FPB in, you'll need the B sear with the FPB lifter.

Why not load 10 rounds in your mags and shoot production?

First off, I don't think lowering the hammer spring weight is a good tactic for lowering the trigger pull weight, that's best accomplished with sear and hammer hook angles/polishing. The hammer spring and firing pin stop geometry play an important role in managing the slide speed when it impacts the frame, probably as much as the recoil spring.

If you're not reloading or shooting USPSA competition skip the Open and get the host, you'll enjoy it more.

I agree, I was just guessing at the OP's motivation for starting this thread.

I spent good money buying my compeditive advantage and I'm not about to start over now!

Shoot Open!

SAAMI says the max pressure is 35,000psi, so why is Winchester telling you the max charge weight is 4.1 if it only yeilds 32,200psi? Does this sum up your question? I suspect the answer to that is Winchester uses some criteria other than pressure and velocity in determining their recommended loads and that beyond 4.1gr the results no longer met one or more of those criteria (perhaps accuracy or consistency).

As long as you don't run the press like a drunken sailor you'll be fine I load on a case feed, bullet fed 650 and if I load at a pace of 5-6 min per hundred rounds I won't spill any, if I load faster bullets start falling over and powder flips out.

I actually have a stash of SP2 which is a French powder not currently available in the US, but the load data is interchangeable with 3N38. When I run out of SP2, I'll be switching to 3N38, in my mind there is no better powder for 9 major, it also works great in 38 super.

That's why 3N38 is the bee's knees Jack! They even have a book load for 9x21 you can load in 9x19 and make major with 115gr bullets: 9.4gr under a 115gr JHP @1.161" for 1,483 fps (171 PF)

I'm a little lost, the relationship between velocity and pressure is going to be unique among different powders and not all powders will have a useful range which reaches the SAAMI max pressure for the cartridge. If I understand your goal it's to find the most accurate load using 147gr XTPs and 572 powder, is that right?
