jack & moonman,
I have a 7x57 m95 and have this to say.....
It also has a slightly oversized bore in so-so condition and it patterns jacketed bullets like a cheap shotgun.
Figuring that I had nothing to lose, I started cast tests with the Lee 130gr and surp860. With that combination I shot the largest cast group (and largest measured rifle group) of my entire life, some 38" for 10shots @ 100yds IIRC, six of them keyholing and two hit perfectly sideways.
Needless to say, I was pretty bummed out and figured I'd be rebarreling the sucker at my earliest opportunity. But then I says to myself, "Self," I says, "I've got 200 more boolits that I cast up for the damned thing and I might as well try another powder and shoot them up." So I tried some surp4895 next and the
first group I shot was just under 3"
(again, 10 shots @ 100yds), and
all groups shot with increasing 1 gr increments of that powder were less than 4". I will rebarrel it eventually as 130gr RN's aren't exactly deer hunting boolits, but don't assume they won't shoot until you have given them a fair chance with some different powders.
If I wanted another accurate plinker, this one would do it wonderfully, but I'd never have known that if I'd given up on it after the first tests, dismal as they were.
This is not to say you will have yourselves tack drivers, but you'll never know until you do some experiments. They might just give you a very pleasant surprise.

I am not going to give up on the rifle yet, but something has got to improve or it will leave my gun safe and I will make room for something else. I am curious, what would you rebarrel to if you did and how much does it cost to do this?
