I actually found the M1 garand to have better grouping then a Mosin does and its semi auto.
was it an original m1 garand? cause you know of course the new ones are going to have better groupings. there really arent any russian firms that "reintroduce" old ww2 guns, you just have now what was available then.
if you really want to compare them, just buy one of the old ones that were refurbished for about $300 (last i checked) but they are only available to shooting competitors, c&r's, or ppl with instructor permits.
i cant remember the website.. dangit, i'll post it when i find it.
i dont really even see why youre comparing them in the first place, its like apples to oranges. why dont you compare the mn91.30 to the springfield 03, if you can find an original. (i have a 1903 mark1, but it was "sporterized" so thanks a lot grandpa)
why dont you compare the m1 garand to the svt40? or compare it to the ab42 ljungman (which is alive today in all our m16 weaps), or compare it to the johnson rifle, or the g43, or the mondragon, or any of the other semiautos produced around that era.
the only reason the garand was successful is becuase it was pushed so hard through to production, it had such horrible teething problems that it was going to be scrapped for the johnson41.
heck the svt40 would've been much more superior if they had toughened it up a bit, it already had everything else in spades against the m1.
