Help Needed

[Papucho]

Yesterday I went to crono my first bullets from Lyman Mold 452630 200 gr. siezed at .451. It is a TC boolit, to fire in my Glock 30 with LW barrel. The bullet was seated at COL 1.235" and was averaging 840 fps. In ne shot in every magazine I shot, third or fourth bullet I was getting FTE (failure to extract), sometimes with a stovepipe and in others, the brass just stayed in the chamber, the gun didn´t cycle. What can I be doing wrong?
Please help me.

not likely the case stayed in the chamber as such. probably rechambered after a short slide stroke. 850fps is not full power load for a 200gr lead. I'd say you simply have to little recoil impulse to work the Glock. A slower burning powder or more of what you have. Or a lighter recoil spring.

I'm assuming it's clean and all greased up.

Thank you very much. I´ll try that.

If you figure out your problem and still want to go with a light load you can get a lighter spring kit for shooting those light loads.

What I can see is that yes it is not a TC boolit, it´s a semi-wadcutter and when the gun is cycling to its rearward position, the spent brass somehow strikes the base of the semi wadcutter boolit that is on the magazine, thus jamming or not completing it´s backward movement. I´ve tried to seat it for COL 1.220", but then it won´t cycle manually.

the 200 swc does like to run a bit hotter then the 230 does to make the gun cycle.
