I found some PPU 7.5x55 174 fmj loaded rounds that will eventually get burned up and the brass reloaded.
I've heard that 7.5x55 can be a more tricky round to reload.
Anyone have any favorite recipes and tips and tricks?

I load reload for that round. It's no different than loading for any other type caliber. Don't know why you've heard it can be tricky. Doesn't make sense.
I load 150 grain FMJ for range and 165 grain soft point for hunting. Powder is IMR-4350. Very accurate caliber.

We have a K-31 in good shape, shoots well. My son took a deer with it on a youth hunt. Most rounds are reloaded. I put it in the 308 realm.
I normally load with H-4895 powder, mid loads since it’s just casual range shooting usually.
I don’t recall anything more unusual than any other rifle cartridge.
Yeah, it can be tricky - Correct dies and seating depth are the reason. If loading for a K31 (I do) I went with Redding dies. I think Hornady did/do make a 7.5x55 die marked "K31" as well. They are designed and made to correctly size the case for this rifle. Seating depth using almost all traditional .308" diameter bullets results in very deep seating, so the full diameter shank behind the ogive won't run into the very short leade.
It would be great to get bullets designed for this caliber having a reduced diameter just below the ogive, so the bullets could be seated a bit longer. I asked Privi Partizan about selling this 174 grain bullet, and they had no plans to do so?
I use IMR 4895 since it goes so well with all of my other C&R rifles, including semis, but also have some 180 grain rounds using IMR 4831 to test someday. Here is some mild data that despite a poor loading density, shoots like a house of fire... Big surprise huh.

I also reload for k31. If possible use redding or rcbs dies. I use imr4064 powder. Make sure to check for bolt crack occasionally. It can ruin your day.
If you can get some 284 Winchester cases, expand the neck back up to 30 cal, and you have just re-invented the 7.5x55. Bonus, those are really tough cases, seem to last forever. For loading data, any mid range 308 Winchester load seems to chrono about the same in a K31. There is a Swiss Rifle Forum. Join. Nice group, and a world of information there.
