I am honestly starting to get a frustrated with my RPr. I have checked all of the screws, done the tape bedding job, cleaned up the trigger, shot with and without loading the bipod, and I consistently get weird random fliers. I can hold the rifle and drill the target right where I am aiming on one shot, the next shot will be a flyer but the scope doesn't move at all, next shot is back where I am aiming. I figured maybe it was me so I shot my 223 and get a sub half-moa group. Other than replacing the barrel or eventually the stock, can anyone think of what I should check next? I have tried Lapua, a couple of CCIs, and Eley for ammo. I am guessing that mine was part of the second batch and I have about 1-2k rounds down the barrel.
Its frustrating bc I can see the potential of the rifle but cant seem to find what the issue is that is causing the fliers.
A couple of things I would check. Examine the bottom of the bolt, the part that rides over the top of the magazine for burrs/sharp edges that can scrape the bullet during feeding. A slight radius and polish will help.
I use 10 22 magazines, and reduce the spring pressure so as to not allow the shell to be forced up into the breech face, again to eliminate bullet deformation. An alternative is to use aluminum tape to snug up the 15 round magazine to get smooth feeding. Either way, I fully load the mags and operate the bolt with loaded ammo, chamber and extract loaded cartridges, and look for deformed/scraped bullets. Adjust/polish as necessary until the loaded cartridges come out undamaged.
Another thing that can be tried is varying the action screw torque. My rifle really shines at 40 in/lbs both front and rear screws.
Maybe I just got a "good" one, but mine has shot numerous 100 yd groups between 5/8" and 3/4" with CCI SV. I have shot 4 different lots of this ammo and it has all been good. Current lot ( I have a case of this lot ) shoots right around 5/8" at 100 yds, chronographs with ES of 17 fps, and 50 yd groups average right around .260".
I cleaned the barrel when new, before firing, with Remington 40X bore cleaner (the old Gold Medallion) as I have all my firearms since it came out in the mid/late 80's. I have shot over 1,500 rounds of varying manufacturers including RWS, PMC, Eley, Win, Rem, Wolf, Lapua, and CCi of bulk and match grade, SV and HV since new. I have not cleaned the barrel since, and won't until accuracy drops off, if it ever does.
I have personal knowledge of 2 other RPR RF rifles and they also shoot very well. One is current as is mine, the other is one from the first run and also likes CCI SV. I'm shooting a 6-24X scope, the others both have 4-16X scopes, and higher magnifications do help with group sizes and being able to read conditions.
Reading conditions with a 22LR is critical at distance, as well as shooting technique ( stock pressure, cheek pressure, etc ).
I actually get better groups shooting off the bench using the bipod up front and a rear bag rather than bags front and rear.
Hoping some of these tips will bring your RPR RF around.
