[QUOTE="Guest, post: 20728"] Gents, A friend and I worked up a bunch of absolutely perfect loads of various OALs over the weekend and headed for the range with them Monday. We found that the ole' Longbow really likes having the bullet right on the lands and charged for maximum velocity and really hates about everything else! We shot three, 3-round groups at 104 yards with the load resting right on the lands. They measured 0.277", 0.873", and 0.375", respectively. All other loads wouldn't even shoot under 1.5"! If any of you are interested, the recipe for the winning load used a 250-grain Scenar HPBT, 89.5 grains of Vitha Vouri N560, and a Federal Gold Match primer. I forget what the average velocities were, but the **** thing was really smokin'! We saw them running from 3048 up to 3080 fps! of course, the barrel is 28". Despite all this wonderful news, there are new problems looming on the horizon. We put a bore scope down the barrel and found an unbelievable amount of copper buildup in the bore. Everyone was incredulous that it shot so well looking like it did. And obviously, I was upset because my cleaning methods aren't working (i.e. Shooter's Choice followed by Sweets followed by JB Paste every 20 rounds). I guess it's that **** patented Lothar Walther stainless steel. Nobody 'round here thinks it'll be shooting well for too much longer if this copper buildup continues. What am I gonna do, guys, short of getting the thing re-barreled? Or should I even worry about it until the accuracy does go south? Regards, David [img]images/icons/frown.gif[/img] [/QUOTE]
