Had a satisfying range session with my new-to-me 6mmBR-Norma. Tried a few different projectiles to see what it likes. True to what @TARGEX told me it happily digests all sorts of loads and projectiles. As ever it pays to find what YOUR rifle likes as they're all different - 6BR is supposed to thrive on 30ish grains of 2208 powder lit by a CCI450 in a Lapua case, add quality 95 to 105 grain projectile and away you go!
This held true with the Sierra 95g TMK - stunning accuracy with a load workup 5 shots across 1.4 grain increments through one tiny ragged hole. Then another 5 at a theoretical OBT node into another lovely tiny group - though for some reason the calculated speed Vs actual was quite different, much slower than predicted.
Next up was Bryn's 105 HPBT - strangely the load of 2208 was not the one. Back to the drawing board. Then shot the workup and another predicted OBT node group with AR2206H - speeds were within a tiny margin of prediction and the group was very pleasing:
Looks like I've found my default load! Time to scrape some more pennies into a pile and see if I can coax Bryn into another decent size session on the press.
