Bought a Ruger Precision Rimfire during Covid, because of it's adjust-ability and some articles bragging on it being great. I had the opposite result. Mine shot 6 moa out of the box. Tried a dozen or so ammo's nothing would work in the RPR.
Problems: clipped tips of bullets, failed to feed about 10% of the time, failed to eject about 20% of the time, rough bolt operation and hard to operate safety. Replaced with a wonderful CZ 457 Varmint.
Improvements:
1) adjusted magazine latch to stop clipping bullet tips
2) after seeing the atrocious rifling with a bore scope, performed a poor mans barrel lapping using JB Bore Paste and Kroil Oil.
Improved 50 and 100 yard 5 shot groups to 2 moa (over 3 times the CZ457 out of the box groups)
Then completely disassembled the rifle.
3) Polished bolt using JB bore past, Kroil and a Dremble
4) Polished Safety components by hand using JB & Kroil
5) Performed second bore lapping paying closer attention to hard spots
6) Replaced the crappy combination spring/ejector with a new factory part because could not locate an improved aftermarket item.
7) Adjusted the factory trigger to the lowest possible pull weight (don't have a trigger pull measuring device).
Reassembled after lubricating everything with Lucas Extreme gun oil and took the rifle to the range. Shot my first bullseye with the rifle after 7 fouling/zeroing shots. Rifle now shoots 0.75 moa 5 shot groups using both SK High Velocity and Semi auto at 50 yards.
Took a lot of head scratching, research, advise from a shade tree gunsmith (who had the bore scope), effort and some $. But the rifle now shoots like it should have from the box. The build quality, operation, design and accuracy still isn't even close to my CZ457 Varmint's out of the box condition.
Personally, I'll never buy another new Ruger product because my 10/22 bought about the same time is even worse. Ruger may have been good at one time, but the two I bought a couple years ago were atrocious. Rather than fixing bad Ruger products, I'd rather be spending $ on ammo and time at the range.
