Will some Laser-Cast 155 or 170 grain lead SWCs function reliably and accurately in the KKM 6" 10mm barrel in a Glock 20?

And what about the stock length Federal Arms 40SW conversion barrel for the G20?

Called them both and got mixed answers.

Who reloads with these target SWC bullets?

Or should I stick to flatpoints and truncated cone lead bullets. They feed fine but the targets are harder to see at 50 yards.

Reloaders?

Shoot 155 grain Oregon Trail Cast SWC in my G35 and they work fine. Just have to make certain that the chamber is fully supported by either measuring spent cases or chamber diameter with a caliper. And although the bullets are capable of around 1300 FPS without much leading, optimum velocity is about 1000 FPS. Also, don't use magnum primers with these bullets, it will cause severe leading. Make sure that the bullet is crimped tightly, bullet setback can be a real serious problem. BOOM!
