I use TCFP and SWC 40S&W bullets from Missouri Bullet Company and they feed/chamber reliably even in tighter chambers of Lone Wolf barrels in Glock 22/27. I use the following OALs with .421"-.422" taper crimp (bullets are sized .401"). With W231/HP-38, I get accurate and no leading loads -

Yes, with any new bullet, you should always conduct the barrel drop test to determine the Max OAL and feed/chamber from the magazine manually to determine the Ideal OAL that will reliably work from the magazine.
