Update: Yeah, it's a bad idea...
I recently bought a K31, which shoots a funny 7.5mm Swiss round that is as close as possible to .308 without being compatible. Anyway, I bought a box of FMJ-BT PRVI ammo to sight in the rifle with, only to realize my local gun range prohibits the use of FMJ (let's not get into the wisdom of that). Though I believe Wolff makes a soft point variation, the vast majority (and some of the best) of ammo out there for this caliber seems to be FMJ.
My question is; is there any way to convert the FMJ I have to "soft point" by removing a small amount of metal right at the tip of the round? I am not attempting to "improve expansion" or anything, just removing the very tip so it is not technically FMJ by the range's standard. I'm sure this would screw with accuracy somewhat, but if the bullet can still operate safely, I'd be able to at least do some <100yd shooting to get a feel for this very cool carbine.
If not, I intend to pull these bullets and seat new HPBT ones (at least the .308 bullet-seating die is compatible with 7.5 Swiss). Would there be any particular set-back issues I need to keep in mind when doing this, or can I just simply replace the factory 174gr bullet with a 175gr Matchking, making sure the OAL is proper for the standard cartridge? Would I also need to re-charge the cases as well? Hopefully someone with K31-specific experience can chime in.
Thanks for the help, I hope I've been humble enough in asking my stupid question...
