What program did you use to measure that group?
It’s called on target pc I think. So you mark your shots with a tool it has and you put this little marker on the center of the hole. You then have to take a reference measure from the image so it can scale. So this target has 1.44” squares. I used that. It does all the math for you.“Hole size”
Nice shooting and I like that program. Very cool!Got to the range today. had to re establish zero after tearing rifle down. After confirming my zero I fired off a fast 8 shot group at 100 to confirm it was all set.

Hornady 140gr ELD-M
EDIT: had to fix the target. someone else mentioned if i put in the hole size diameter and i didnt change it. i also double checked the reference measurement and that was off as well. Guess i didnt save it when i did it? anyway, changed a bit from .48 to .66. still not bad for the ol RPR and me. Personally, i still think this target is off. it looks more like a 1 MOA group than .6 MOA. i ll have to make sure i know what i am doing with this program. me thinks if i put calipers on it it would be closer to 1 MOA. not as impressive i guess. Well, another edit, looks like it is in the .6 range.

Yeah I’ll probably do something similar like put a quarter on the target. Either way though the calipers and the program are in the ballpark of each other so we can calll it .6 ish and be good enough. Point being this a factory barrel with factory ammo and an 8 shot group not a cherry picked 3 shot group with hand loads. My love hate relationship with the RPR lives on but like I’ve said before bang for buck it’s a good rifle.When using calipers it is much easier and more accurate to measure the outside of the holes/powder mark as shown above and subtract the bullet diameter.
On the programs I usually lay a tape measure across the targetbsomewhere so when I take the picture I can use that as the fixed measurement in the program and I can always reference back to it.
Don’t get caught in the weeds on the gens. It’s the same exact rifle. Just different standard equipment. Gen 2 is different because it had a new hand hard and a muzzle brake. Gen 3 has a new handguard. That’s it.Specs look like it, but I'm not sure if anything else is different. has anyone put the gen 3 handguard on a gen1? Or, what's the best fit and tolerance/rigidity handguard out there for a Gen1?
I’ve always cleaned mine about every 200 rounds. It now has 2700 rounds through it with no noticeable loss in accuracy. Still going strong!The RPR has proved to be a very predictable rifle. It does well with factory ammo but really shines with handholds. The factory barrel does well for a long while as well. The one thing I found over the past few years was that you will want to keep the barrel somewhat clean. Once it gets overly copper fouled the accuracy goes away fairly quickly.
Going to 1000y and beyond is very doable with the 6.5CM on a regular basis.
Very first upgrade most RPR guys do is the stock. Mine was funky like that too when I first got it but then threw magpul prs on itIm seeing some weird shit on my RPR stock. The length of pull adjustment seems to slip, but it is not getting shorter its getting longer.
Both locks are tight WTF?
I may have to take it apart and see what is going on.
In the beginning I cleaned every 350 rounds. That number slowly declined over time. I always try to clean well but leave a little behind so the fouling process is a little shorter and easier. At around 2k rounds the accuracy dropped to around 3/4moa which was terrible for this rifle. Initially I thought the barrel was giving up a bit but decided to start with a good cleaning to get a base line. I decided this time to go down to bare metal. The lead and copper just kept coming and coming... for 6 hours. I later surmised that I had been leaving a bit too much every time. Anyway I got it clean clean and was back to sub-half Moa. If Ruger sold the factory barrel separately I might have stayed with that as the replacement when the time came to rebarrel. They just work.I’ve always cleaned mine about every 200 rounds. It now has 2700 rounds through it with no noticeable loss in accuracy. Still going strong!
I run the 18” MI. I would highly recommend it. Gets that bipod just a bit further out for extra stability.^^ Long and Trob, I pulled the handguard, removed excess oil, and reassembled with blue loctite. It has been straight, and is now, but the allen heads were unevenly torqued. It's about as tight as it's going to get without stripping the threads. Still flexes back and forth with some leverage, returns to center. Not only does the Samson have a flex, but the OD nut and shims seem like a bad choice. I will likely go with the MI in 15" for the 20" barrel. Nut is one piece no shims and the only decision seems to be MI or the Seekins. Thanks guys.
Looking at some of these number here should give you a good starting point:Can a Brother get some Load Data Please....
Looking at some of these number here should give you a good starting point:
Mine is a .308 and I've found loads from other guns to be as good as the kind of thing you're looking for. Every gun, even those of the same model, are different and the load can be quite a bit different. But, these are good starting points for load development and shouldn't take long to find a good node.Thank you Sir..
I was primarily hoping that somebody could share their RPR specific load data with OEM barrels.
For sure, most reloading manuals are saying start around 39grs- up to 42grs, which in the scheme of things is a pretty narrow window, so it should only take me a day or two to find my node, play around with seating depth, and neck tension. I was just so happy that I found two 8lb jugs of H4350. I haven't measured it yet but I'm pretty sure the bolts on the RPR don't utilize a small firing pin hole so primer piercing, and cratering is a bit of a concern, I may have my bolt head bushed by LRI.Mine is a .308 and I've found loads from other guns to be as good as the kind of thing you're looking for.
