hahaha its mostly been filing and swearing, I think "Engineering" is a bit generous! Sorry I should have added more detail to the original post. Its based on an Army L85 airsoft RIF (don't get me started on the legalities of RIFs etc, had a huge debate before spraying this proper colours and ended up getting an airsoft defence to be safe) which has basically been gutted with only the shell, sights and the trigger mech being retained. I originally started out trying to do it with a Ruger 10/22, which as a barrelled action (over 24" of course as is the 597) fitted very nicely into the chassis. However the trigger linkage was going to be a pain and the magazines were far to wide to work sensibly with the mag well. So I switched to the 597 which was an OK fit, but if you look closely you can see the barrel angles down a fair bit, I have a large shim under the acog to get enough elevation due to this. This is just due to the way it all sits together, but its not that noticeable that it annoys me. The trigger was pretty easy and its a direct linkage so very very crisp (unlike my HTA 90/22 which is smooshy as heck). The only real issue left is to get it working with decent mags and re-introducing the airsoft mag release into it, currently the 597 25rounders just "push fit"

Just got reminded of this little project. Not everyone’s cup of tea this but I’ve enjoyed crafting it and looking forward to picking the project up again after a rather crazy few months. It’s all working fine I just need to work out a better magazine system, have just picked up some cmmg mags from the classifieds. currently works with standard 597 magazines but it seems a shame not to finish it properly.

I’m still chasing the accuracy on my RPRR but haven’t had time to shoot since June. I had a brief bit of time today to play with the barrel tuner but not to a proper extent (no real scientific method, just 1/4 turns to find one it liked) Of the three targets (100y) the middle one was my “I think this is tuned” setting from playing at 50y, I cranked it one way a bit shot one, then back to tuned then more the other way and it seemed to go back out of tune. (The picture has rotated when I uploaded it, so in reality it is vertical spread not windage which is what the tuner seeks to improve ) I then shot the glo sticker at 50y to be sure. All of these were shot with my length sized SK Long Range Match ammo, I noticed much less consistency when shooting unsorted ammo so I’m going to continue to do that. It’s probably about as accurate as I am going to get it now I think, I have to accept that there are still fliers, they show up on the chrono and you can hear the difference. At the same time my wind reading ability is also improving as is my technique so these are the next things for me to improve for sure.

That sir, is an excellent question…. Just checked and it’s a 1”

Thanks it’s a cracking little scope to be honest, and yes still available at this time

Hi All, After testing ammo in my RPRR I’ve got some left: 119 RWS 100 372 Eley Match £65 for the lot collected from mid devon, I reserve the right to ask to see your license prior to agreeing to meet. Half of the Eley Match has been sorted and batched by length using a G3 guage and it’s all marked accordingly so a good chance if you fancy testing if it makes any difference in your rifle. Ive settled on SK LRM and it does shoot better when batched into lengths (you can read some of my essays here

Up

Might take something cheaper (sub £500) in PX

Which size are these? If they’re 308 sized I’ll take them

Up we go

Second dibs please

No it was originally listed £100 more 👍

One and only price drop

Up we go

IOR Nemesis 9-36x56 FFP MRAD This has been sat on my shelf for a couple of years while I was waiting for my .300 to be imported. It’s been for one outing on it and it’s an absolutely incredible scope, but due to personal circumstances I need to free up some money so it’s been replaced with a Riton. Includes scope, tier-one mounts, sunshade, bikini cover, manual and warranty card. I don’t know why the stupid iPhone has set the photos sideways but I am happy to provide any more required. £1329.60 posted RMSD to your door, bank transfer or PayPal (with no fees) or collection welcome from mid devon for £1300 SOLD

Yeah I was really surprised to be honest, I was also hoping it might count for some of my fliers!

I tested my SK long range match and it was all within one thou so IMHO not worth the additional effort, the “seating depth” is worth persisting with IMHO. So I tested 300 Eley Match and it had less variation than the SK LRM with only 5thou difference rather than the 8 observed with the SK. However IMHO it did not shoot as well through the rifle once sorted as the SK did, more vertical deviation, but the seating depth was much less, averaging 0.015 vs the SK 0.025. I didn’t get the failures to fire like I did with the team. 80 Shots of match over the chrono gave an ES of 57, the 30 SK I tried gave me 34. Interestingly using the PITA single shot sled for the RPRR was actually a PITA with match, to the point I was going to bin it as I assumed it was knackered. But then I decided to shoot the 30 SK and every round went in silky smooth. Don’t get me wrong, match shot well (and it should for the price) but I’ll be sticking with SK on this rifle if the batches prove to be consistent.

Message sent regarding grips 👍

Is there much point in tuning those? 🤣 My understanding is that you tune to a range, it never made a lot of sense to me but apparently a 50y tune can be different to a 100y tune with the same rifle and ammo

Yep that was the starting point! I think my list was Team, Match, SK Standard Plus, SK Long Range Match, Contact, RWS R100, Action, RWS HP subs

I hadn’t considered that actually, I just assumed that sorting ammo could only make x difference and the tuner might not improve that, but you’re right of course and the two working together should be the best outcome. I’m just not sure if I’m throwing good money after bad with the RPRR, it’s hardly a top grade rifle, but it’s fun finding out!

I had considered the hornady concentricity tool…. But I’ve got enough variables at the moment! I can recommend the gauge, it doesn’t take long to sort the ammo and I’m pretty sure it’s an improvement, but it’s not cheap. I’m wondering if the gauge and tuner are kind of overkill and you don’t need both… but let’s see!

I agree, I spend time working up loads for my centre fires so why not for the rimfire which I spend more time shooting at the moment! The gauge was an import from Neconos who just happened to have a new batch of them. I had a very quick fiddle with the tuner just to see if it made any difference, I definitely detuned the rifle just fine!! I need more time to play as I’m throwing too many variables around at once now! Really I need to reconfirm the sorting results again at 50 and then at 100 and then introduce the tuner. I shot some groups at 100, but there are still rounds going where they shouldn’t, if you know what I mean, you hear it and you just know it’s going to be off. One group was .6” at 100 but that was a one off, most are around the inch. I shot the mini f-class targets in a bit of a rush which gave me 10shot groups in the 1.3” region, we did have some very light gusts which could account for some of the lateral movement, plus human factors (i.e me flinching etc) My next steps are 1- measure up a new batch and tighten up my tolerances, previously I’d take anything from say 0.0245 to 0.254 and call that “0.025”. I’m then going to sort these by rim thickness by using a hornady gauge as well. 2- shoot these at both 50 and 100 along with control groups on the stillest possible day I can get 3- see if I can make a consistent difference with the tuner at 50 (I’ll be using hopewell) 4- see if the tuned rifle can handle a wider variation of seating depths I’m aiming for consistent 1 MOA results, maybe I am dreaming with the RPRR

Sold thank you
