I have lots of GP11, so I can't comment on the PRVI 7.5x55, though I have had decent results with it in other calibres. Norma also makes 7.5x55, with their Oryx hunting bullets. Spendy, though.

Reloading the Berdan-primed GP11 cases is not impossible, just a bit more involved than reloading Boxer-primed cases. I have a lot of GP11 once-fired brass, so I am set up for reloading it. The tricky parts are:

(a) getting the old primer out, without damaging the anvil in the case - this can be done hydraulically (fill the case with water and bang in a dowel) or using a tool (bought or improvised):

(b) finding Berdan primers. Start with Grafs. They often offer the Wolf-brand ones.

The ammo shares components with .308.

.308 diameter bullets and powder, yes. A careful reloader can be guided by published .308 loads, though the Swiss GP11 cases are substantially thicker brass than most commercial .308, so the volume is not the same.

I LOVE MINE - and other than my Garand and M1A, that's my next favorite rifle, and I don't even worry about keeping it in the safe (simply because most crooks would pick it up, handle it, and decide they didn't like the feel of it and it didn't feel & look expensive enough to get caught stealing - simply because they had no idea what they were handling).

BIG-5 used to have sales of them all the time, for $89 a piece (while on sale - but the ammo for them was NEVER on SALE). I firmly believe those days are LONG GONE.

YMMV!!!!
POLITICIANS & DIAPERS NEED TO BE CHANGED OFTEN AND FOR THE SAME REASON

A person properly schooled in right and wrong is safe with any weapon. A person with no idea of good and evil is unsafe with a knitting needle, or the cap from a ballpoint pen.

That's what my friend does. He swears by it.

Short answer: No

Long answer: even at $300, they are a screaming deal. If you look at the quality of the metal and machining, that would be a $2000 production cost today.

There is still GP11 available. Buy 2 rifles and $2000 worth of surplus GP11 and you are set

If you plan for a rainy day and want to reload, do yourself a favor and buy a case or two of Norma 7.5x55 brass. The other major PITA is finding Berdan primers. Norma brass is boxer primed.

A K31 is how it usually starts. Then bayonets, including a sawback. Then you'll need an 1896/11, and a K11. That's where my sickness paused. Of course, it's just going to take the wind blowing from the right direction for me to pick up a 1911, and should I ever hit the lotto, a ZfK-55 and a K-31 .22 conversion.

Also, let me help: Simpson LTD usually has good prices on them.

Jag it's even worse than that. Having never used in a war ebay is full of their high quality and good condition surplus field gear. Much of it is the old salt and pepper canvas combined with leather and is as beautiful as it is functional, made with the same precision and attention to detail as their rifles. I used one of their salt and pepper rucks every day for school and love it.

Well, my AR addiction caused me to blow my gun budget for the month. I found a screaming deal on an upper I couldn't pass up.

Looks like the K31 will have to wait a few weeks.

Welllll if you have old eyes, scope mounting can be a problem. Doing a Scout Style with a long eye relief scope is probably the best route.
Also as issued it uses what are supposed to be throw away stripper clips, a cardboard and sheet metal affair. There were plenty of the clips around in the 1990's. I guess if you practice a lot and hold your mouth right you can reload fast. Be aware that the fired case is ejected vigorously straight up and back over your head. Some one may make a removable box magazine set up for them now. It has been a couple of decades since I had a K-31. The trigger pull on them is simply amazing.
