Well, the board is either fixed, or it's going to run terribly. Cross your fingers and hope for the best. I'm at my technical limit right now.

"Mexican Match" .45 ACP?

#1 Post by professrh » Thu Aug 16, 2018 9:17 am

So, I've upgraded to a .45 ACP for my backup sidearm for hunting in wild-hog country. However, I'm having a hard time finding 230-grain RN/FP ammo to carry in it. Any thoughts on the possibility of pulling the original RN FMJs and replacing them with flat point bullets?

For the record, the weapon is a Springfield XD-S.

Thanks!

As long as the bullet is the same weight or lighter there will be no problem. Seat to the same length if possiable.

Excellent. Thanks!

Any special considerations relative to crimp?

A slight taper crimp is OK. Never roll crimp the .45 ACP. It head spaces on the case mouth.

Thanks!

Would you recommend using one of these, or just applying crimp with the bullet seater die?

FOR HANDGUN AMMUNITION THAT MUST WORK
carbide factory crimp die
[ OPTIONAL ]
A carbide sizer sizes the cartridge while it is being crimped so every round
will positively chamber freely with factory-like dependability. The adjusting
screw quickly and easily sets the desired amount of crimp. It is
impossible to buckle the case as with a conventional bullet seating
die. Trim length is not critical so this extra operation takes less time
than it would if cases were trimmed and chamfered. Revolver dies roll
crimp with no limit as to the amount. A perfect taper crimp is applied
to auto-loader rounds. The crimper cannot be misadjusted to make a
case mouth too small to properly head-space. A firm crimp is essen-
tial for dependable and accurate ammunition. It will eliminate the
problems of poor ignition of slow burning magnum powders
