I have been loading 2400 in 10mm for my Glock 20 with excellent results for probably 20 years or more. I had to put a 22 pound recoil spring from Wolff in. I use Starline brass and toss them after the second use.
That's definitely not where I want to go. If I'd need to run 2400 that hard to get results, then I'll just nip that idea in the bud. Not that I'd say you're doing it wrong, I just don't want to go
there.
