H110 and 2400 are both poor choices for the 10mm. They take up too much case capacity, and the burn rate is too slow. They will go bang, but velocity is relatively low compared to more appropriate powders.

Yep, coated bullets (Hi-Tek, powder coating, etc) can do anything plated bullets can do, and more, with no disadvantages. I don't see any reason at all to use plated bullets these days.

Shane, since you'll be using an ISMI spring in that setup, get the heaviest one you can, either 22 or 24 lb. I've tested a bunch of these springs; the ratings are false, and even the heaviest spring isn't too much.

I don't generally share load data, and pretty much only shoot my own cast bullets anyway, so what I have wouldn't help you much. However, your loads for this setup don't need to be anything different than any other 10mm, so just start with some book loads.

However, what I gathered from people using the QuickLoad program, shows pressures above the SAAMI MAP. 
These included; 9.4 grains LongShot @ 58,823 psi, 10.5 grains Blue Dot @ 42,628 psi and 12.6 grains AA#9 @ 60,093 psi  with the 200 Grain XTP.

Keep in mind that Quickload generally gives very conservative results. IMO most Quickload pressure data is a rough estimation of the worst case scenario, and nothing more.

I would rather have a 230-ish gr WFN in the 45 Super, than either of your other options. A little more velocity, and still more than enough penetration. I'm not a fan of the heavier weights like that 255gr in 45 Auto/Super; they give up more than they gain IMO.

That should be a good one. The nose is a little on the wide side, not a big deal but it may require seating deeper than 1.260" in some magazines.

The TC nose shape is a poor choice for heavy 10mm bullets, but unfortunately it's the most common from commercial casters too. Something with a tangent ogive, small lip at the driving band, and about .280" meplat diameter is best, in my experience.

Gotcha. If you want a 6", you won't regret buying a KKM. You might regret a Storm Lake or Lone Wolf, or may have to wait a while for Bar-Sto. That's the way I see it.

I personally think the stock barrel is fine, and actually better quality than most aftermarket barrels. Any issues with lead are resolved by shooting lead bullets that are large enough and hard enough. Don't use loads that are stupid hot, and you should have great results.

That said, if you want an aftermarket drop-in barrel, KKM is the way to go.

I'm going to try the EGW flat bottom fp stop with 25lb mainspring hoping to be able to use the 20lb recoil spring.

Sounds like you're on the right track there. I wouldn't go any heavier on the recoil spring than you have to.

Probably a good idea to have Clark fit it; at good tight correct fit makes a difference in durability with these hot loads.

SOLD

I have a few 10mm magazines for full size 1911's. These are new in the packaging, except the Colt which is new but just in a ziploc bag. $25 each plus shipping, free shipping on 2 or more.

- Colt, 10mm, blued, 9 round (1 available)
- Wilson #47NX, 10mm, stainless, 9 round (1 available)
- Wilson #47NXE, 10mm, stainless, 9 round, with extended base pad (3 available)

The shortage is better for the industry overall; follow the money. (I said industry, not consumers!) A shortage makes people buy stuff they wouldn't normally buy, at higher prices than they'd normally pay.

Who here wouldn't buy a brick of .22 bulk ammo for $20 if you found it, even if you didn't need it? Compare that to a couple years ago, I'd see bricks on the shelf for $12 and walk past, thinking "nah, don't need any more today".

Don't take this the wrong way (I don't say this to be rude), but - you just now figured out the .40 is a viable defensive cartridge? You might have some more catching up to do...

As long as they are accurate in your barrel, that is a pretty good bullet. Maybe one of the best designs out there in the 10mm heavyweights. Nothing wrong with a 200gr @ 1200 fps!

Again, porting does nothing to slow down the slide. The only thing working for you in that setup would be the Sprinco system, which may prevent battering at the rear end of travel, but will put that stored energy right back into the slide when it goes forward again.

If you really want to do a 460 Rowland, you'd be better off with a standard length Witness with an extended barrel and a brake, to do it right.
