I'm trying to get my ducks in a row before I buy a used Delta Elite tomorrow.
Congrats on the Delta if you get it.
The shop carries ppu 10mm ammo and I need to know if this ammo is worth a hoot. I assume it is as I have had great luck with ppu in the past.
PPU's 10mm is crap 40-level ammo. Plus, it's dirty. Avoid it. There are way better off-the-shelf choices. Shot up two boxes of it, then pitched most of the brass as unsuitable for reloading. And I'm not the only critic of PPU's 10mm product. Do some research on boards like 10mmFirearms.com and GT's 10Ring, where 10mm fans post their experiences and reviews of 10mm-related stuff - ammo, guns, gear, etc. I've shot other calibers of PPU ammo before and all of it was fine, but PPU really dropped the ball on their 10mm product.
And remember, ... you're getting a 10mm Delta because, presumably, you want to shoot
real 10mm ammo in it, not soft-n-fluffy 40-level fodder that's masquerading as a 10mm. If you only want to shoot at .40S&W velocities, skip the Delta altogether and buy one of the many pre-owned .40 pistols collecting dust on gunstore shelves.
I also intend to reload for this pretty lady so is it a good choice for brass?
Reloading for the 10mm will really open your eyes to the capabilities and versatility of this magnum-level auto cartridge. That said, again, the PPU brass is junk, like the ammo. I agree with the Starline brass suggestion. I've also had good experiences with cases by PMC, Winchester, & Federal.
Have fun!
