A 452 is always going to be hard to beat.
Re: Accurising the .22LR round
The latest addition to my arsenal of tools chasing the rimfire accuracy!
A very rare GG G3 Gauge designed to measure base to “ogive” of rimfire rounds to find the best “seating depth”
I was lucky enough to buy this one but no doubt with the right tools and skills it would be relatively easy to make one with a .22 chamber reamer

Lovely. Robert of CG fame and I talked about them many years ago and I wish I had accepted his offer of the drawings for it.
Re: Accurising the .22LR round
Just ran 7 boxes of SK long Range Match through it and came up with a range of around 0.0235” to 0.0325” which I rounded to the nearest tho with the majority sitting in the 0.025-0.028” range.
So out of interest I ran 20 RWS100 through it (what’s that, £15 a box now??) and that had a spread of 0.002” BUT it was 0.019-0.021 however it’s never shot brilliantly through the RPRR so my hypothesis is that the RPRR will (finger crossed) like the majority in the 0.025-0.028 range

Re: Accurising the .22LR round
Keep us posted, please! Will be interested to see how much of a difference it makes overall.
I guess the key is finding a brand & type of ammunition your rifle shoots well and then working down from there!

Wow! Regardless of the range that’s some shooting!

Re: Accurising the .22LR round
is that 40 x's? been so long since i shot a card...
When guns are outlawed, only Outlaws will have guns
Re: Accurising the .22LR round
Although light on detail, I'm pretty sure that was 50m, It would appear to have been shot on the Eley test range, probably from a fixed rest. In these batch testing sessions with rimfire the group size is measured "outside to outside" . One 40 shot group, 13mm is just about two bullet widths.
Re: Accurising the .22LR round
Wow.
I just checked my "fluked" group with SK LRM and it was 11.5mm edge to edge but thats only 5 shots, 25x scoped, off a solid rest & bench and 50y
To be fair thats what I am aiming for as a consistent group, I am hoping to whittle the ammo down so any bigger groups are 99% my fault
I do also have an ADT tuner coming but I will be assessing the impact of the gauge before adding the tuner, as soon as the cows are out of the range
