I have three MkIIs. All are used, so I don't know the round counts, but I've put a few thousand through the one I've had the longest. AFAIK, all have the original recoil springs.
I've generally shot a mix of HV and SV ammo. I used to be partial to AutoMatch. A few years ago I bought several bricks of Aguila SV and HV when they were still Eley primed; have a couple of those left. New version Aguila looks worse in targets I've seen people post online, so I guess I'll be using CCI SV from now on when keeping score. I have a few boxes and was able to get another brick of it a couple of weeks ago.
I also succumbed to the silliness of getting a couple of bricks of Aguila Interceptor a little while back (a knock-off of CCI Velocitor, as far as I can tell). Trying to get more "power" out of a .22LR doesn't make much sense, but I'm a sucker for gimmicks, I guess!
So, my question is whether it's going to beat up a MkII to shoot that much of this stuff. Looking at parts, I see that Volquartsen sells standard and HV recoil springs. Should I dedicate one of them to the supersonic ammo and put an HV spring it it (and maybe replace the standard springs in the others with new ones, while I'm buying parts), or is the difference not really important? (I've always thought that MkIIs were fairly insensitve to ammo, unlike, say, High Standards, but perhaps I was misinformed.)
