Got the little RARR 300blk singing. Had to sand out the barrel channel. Factory trigger was mushy AF so replaced her with a Timney. Added a permanent cheek riser - American style combs aren't to my taste (especially for explicitly scoped rifles, I don't understand Merica
).
The rifle loves Hogdon's Lil'gun paired with (cheap) Speer 125gr TNTs. Using CCI400s and Lil'Gun standard deviation is on the higher side. Nevertheless the RARR does
not like hard CCI450 magnum primers, and light-primer strikes like a sob. Headspacing is sure on the liberal side, at least 5 thou over SAAMI (as far as I can tell without the right gauges). Paired with under spec shoulders you might have issues - luckily I'll only be collet neck sizing (suits me). Basically you can't use hard primers, and some factory ammo might not work (depending on shoulder height).
Barrel stays comparatively cool compared to other calibers I have. Easy to reload with mild recoil. It consistently 3-shot groups into MOA at 200m with this load, that's as far as I've stretched it (so far). Weighs 3kg scoped.
This is my first Ruger, and indeed I now like this little package.

- 50m group - 18gr LG + CCI450s = light primer strikes + poor accuracy. NOPE.
