I reloaded 200 gr Cast Performance in new Starline brass. Trimmed, sized, correct overall length is correct. The problem is that the bullets won't even chamber. I have a Barstow barrel on the gun. The bullets will drop into the barrel but if I chamber a round the slide and bullet jam up. I have a 21 lb recoil spring in the gun. Any help would be appreciated

Did you plunk test them before you loaded a bunch of them? OAL is kinda a suggestion... you need to adjust for every pistol's chamber and leade.

Color the round win a sharpie and then try to chamber it. See where the wear mark is.

Finished rounds dropping into the barrel freely (with a "plonk") and spinning without hitting the rifling is your Max OAL/COL. But Max OAL may not always reliably feed from the magazine and you need to incrementally decrease the OAL (say by .005") until they do which is your Working OAL.
SAAMI max length for 10mm is 1.250" but if your Max OAL is longer (like 1.260"-1.270"), incrementally decrease the OAL until rounds reliably feed from the magazine.
And do consider using longer than SAAMI max length OAL. With my 40S&W Glocks with factory and Lone Wolf barrels (which have very tight chambers), while SAAMI max length is 1.135", Max OAL was 1.149" with various 180 gr TCFP bullets (including MBC lead bullet) and 1.145" was the longest length that fed reliably from the magazine and I ended up using 1.143" as my Working OAL for TCFP bullets to work in all pistols/barrels/magazines - https://www.thehighroad.org/index.p...-for-lead-plated-bullets.743416/#post-9362819
With RMR 180 gr RNFP bullets, Max OAL was 1.165" but would not reliably feed from the magazine until 1.160" and I ended up using 1.155" as my Working OAL - https://www.thehighroad.org/index.p...ick-plated-bullets.761471/page-3#post-9639622
Thanks all. OAL is 1.25 in. There's no taper on the bullets until almost to the nose of the bullet. The bullet can't be seated much lower without problems. Im going to pull some and load them into empty shells to see how far the bullet has to be seated to chamber.
