1066 There are certainly a lot of conflicting theories out there. It seems to be split between old school Calfee and the upstarts like Vudoo who are challenging the norm ( and certainly seem to be getting good results 🤔). Distances that 22rfs are shot, being stretched. To me going 100,200 and 300 seem sensible. When I see 500 and 1000 it feels like you a lobbing lead? I’m going to be trying 500 next week so will see how it goes or how others who do this regularly get on. Barrel length seems to hold mystique, ‘ ooo the bullet is slowing down etc’. As you say target pistols had pre

1066 interesting videos 🤔 Tuner plus a ‘bloop tube’. Was there not some discussion/ ideas re the bullet emerging into still air as being advantageous. Yes single tight group/one hole at 50 is the goal - consistently Terry

Think the grouping is currently all down to me! Bit like my old school reports - 'could do better' My understanding re tuners and from previous experience with a Harrel's tuner is it made the barrel 'dead'. The groups at 25, 50 and 100 were better, more round, less 'odd one out' (that bugger that spoils a 5 shot group 😒). Also ammunition tolerance was improved, not saying totally different ammunition make/model, just similar ammunition. Now I've a Ezell particle damper on this rifle - going to start playing this Friday, will revert with results, we will see 😉 T

Started on the ammo testing at 50 yards. the rifle like Lapua/SK which is about right as the chamber's to Nevius's spec Biggest limitation will be me, holding consistently is going to be my first hurdle, keep pulling a shot. The New SK flat nose match was pretty good, did not like Tenex but my gut says I'd not shot enough to swap the different bullet lubes? All shot from the bench, rifle was as delivered from the Smith, tuner installed but wound right in. the 50 yards range might not be 'up' for sorting the tuner , think I'll use the local indoor 100yard as this will

Wipe-Out’s accelerator and Tac advantage before I leave the range, push thru when I get home , leave Ballistol in the gun. All applied with felts. Carbout now and then. Each rifle’s different and requires and regime adjusted to suit. whatever your are happy with really. ‘Cleaning’ came up at my club recently and I obtained a top F Class shooter and a known top PR shooter/gunsmith/instructors methods - you could not have found two diametrically opposite techniques ie there is no correct way 😉😂

Duster, There are a lot of good products out there but the subject of how to clean a rifle is well up there with political and religious discussions!! 😉😂. What issues are you seeing that makes you want to polish the bore? would be my first question. As an answer to bore 'polish', I've used Flitz, Iosso (with tiher dedicated blue nylon brushes) and JB bore paste (both flavours) for specific purposes. There is no reason to think the the KG product would be any better worse than any of these. Terry

Was indeed good to get out and shoot Ewen, catch up with you and a few other folks, the 600yard F class pm was also very enjoyable. Believe that is your 22rf stick in the background.

Had my first go at 22rf LR on Sunday. A 300 yards shoot (very well) organised by the GBFCA and sponsored by RUAG who made some rifles available and also supplied ammunition for folks to try in the form of R50, R100 etc. Very interesting for me, first time out with new stick I collected on Friday and came away with a few things: Great fun, will be doing it some more when opportunity arises. The wind is a bloody killer 😉 ERATEC bases do what they say on the tin - put 40moa onto the base (which is a doddle to do) and it moved the poi by 41.75" and back to zero = good enough

OoTo2 Ive had my rifle cambered to suit Laura/SK so have a few of these in hand to get going with. Couple of rifke projects on the go so looking fwd to doing some faffing around 😎

NiD Concur That is the starting point 👌😎

^this^ is I feel all part of it 😀 Looking forward to playing once I get my paws on my rifle.

The concentricity gauge is for the munitions, the tuner is for the rifle, think they are mutually exclusive. Do not think normal CF concentricity gauges work well with 22rf ammunition, least not without a bit of faffing. The Nielsen is designed specifically for rf and as such is easy to process swiftly.

Ad3 Tuner once setup should make the groups ‘rounder’, least that has been my previous experience. Thank you re Neco, might try to sort one? Have you looked at concentricity gauging using something like the Nielsen tool? Having measured some reasonable quality ammo found a good few that were outliers. T

Lee, What are you shooting to get 3400 mv with 108g - that’s no slouch 🤔 I’m using a 1:7.5 twist in a 6mm Dasher and with 105 Bergers that is a comfortable 2970 but you are ‘way’ past this configuration Good luck and I assume you have a spare barrel on hand 😉😂

Ad3 Nice efforts re testing. Think the 22rf needs a bit more attention to deliver the best out of it. Be interesting to see your results at 100, if your initial findings follow thru 🤔 have you decided on what method to set up your tuner, just about to set up a new rifle a d tuner myself, have used the Purdey Rx previously but think the Hopewell looks more ‘solid’? Can I ask where you obtained the the G3 rim to ogive tool? Good luck Terry
