Worn out tooling won't create the same design of rifling. Both my CVA rifles have it. The chatter marks in the grooves could be explained by the worn tooling as could the inconsistent bore diameters but not the rifling design itself. This was done by an engineer on purpose.
My 50cal Plains Rifle is very accurate with several different loads but the bore is uniform and and a bit on the snug side. I love that rifle. My 45cal Paramount on the other hand is overbore at .4535 so regular .451 or .452 diameter bullets fall like a stone all the way to the breech plug. I can take .453 Fury 265gr STB bullets and knurl them between 2 files so they fit snug enough to stay seated but that limits me to 1 bullet that I have to manipulate just to be able to shoot it. And I have not been able to get that bullet to group well so far.
WOW! That looks terrible! I hope they make it right.
Green Mountain is an American company that takes pride in their products. CVA just pumps them out and hopes for the best.
Sure seems that way, glad midway is stepping up
for MidwayUSA !
Yep, what idiot dreamed up that rifling?
! Should they return them? 
Shoot them. I'd bet they shoot fine.This is what the Rifling looks like in my two friend’s New Optima V2s
RobRed did you keep yours, if so did you Polish the Bore?
Jeff I was having the same problem with my old spin jag with patches coming off shooting my Knight. It was a real PITA at the range having to put a worm on the rod to get it out. Turns out the little "teeth"/knurling in the jag was wore out. I switched jags and no more issue.welllllll ......................... i called midway about sending it back .
i was cleaning the barrel and my cleaning patches kept coming off on the out stroke . they kept sliding off at the bottom seemingly as soon as i pulled back on the RR and i had to keep taking the breech plug out to push it out . there is also less pressure going down the MRX barrel with the jag/patch than the old optima . i was using my range rod , not the bunji that comes with it . i still haven't gave steve his 2003 optima back yet and i used the same CVA patches and rod on it and it did just fine , no issue at all . i looked in the barrel and the rifling is MUCH shallower than the old optima . Madison at midway put me on hold and came back and said she was gonna set it up but they want me to send pics of the rifling so i will do that . but i told her if i cant even swab the bore without having to pull the breech plug that that was a MAJOR problem and that i now have zero faith in cva guns . i was polite and didn't raise my voice or get crappy but i stressed that was absolutely not acceptable and mentioned the problems with the 45s and that i thought the 50 would be ok . this has not been shot yet , i was just cleaning it to play with it a little . anyhow , i'm disappointed of course , particularly since this was a gift . she said they'll be open monday so i'll e-mail pics tomorrow (and post them here) and hopefully it's a trouble free return .
