I dunno.
I've got a few milsurps that would probably put a new Remington or Savage to shame on range day. (not a PSS, FP-10, VSS, or Sendero, mind you)
1. Swiss M1911 Schmidt-Rubin (the older one with 30" barrel)
2. A couple of plain-vanilla M96 Swedish Mausers
3. A 1941-vintage Swedish AG-42B Ljungman
4. A 1917 Enfield Lock NoIMkIII* SMLE
5. A sporterized 1917 Amberg Gew98 with crappy bore
6. I shouldn't even mention my Remington 1903A4 2-groove sniper
7. An October 1918 Springfield 1903
All of which are tight groupers, and all, save for the sporter Gew98, have won me trophies at "run what you brung", or 500 meter battle rifle silhouette matches. Point is, there are jewels and there are dogs out there in milsurp land. Knowing what to look for in the gun's condition, and also what to feed them is probably the biggest battle in the accuracy equation. I do have the luxury of feeding all of the above my carefully-crafted handloads, but those handloads are also matched to each individual rifle's particular quirks. (Save for the Swedish Mausers, they're amazing in that they seem to shoot anything they're fed particularly well, regardless of bullet weight or style)
Regardless, I'll be more than happy to put my money where my mouth is and bring a milsurp to the game that shoots where it's aimed. I haven't been bitten by the Mosin-Nagant bug yet, but when I do, I'll be just as vigilant in making it shoot, otherwise it'll get dumped like a bad habit and I'll start over. (I did that dance with a counterbored MAS-36 not too long ago)
