Tested a few last week:
Lapua brass
Murom LR
73mm/2,875" COAL
VV N150 powder
175gr ScenarL hBN coated
24" factory Tikka barrel
Temperature around 10°C
Did only 3 shot groups as i was mainly interested in speeds i'd get but all loads were rather consistent with best being .250MOA and worst being .8MOA
Speeds were:
44,5gr @ 2539fps .4moa
45gr @ 2563fps .5
45,5gr @ 2578fps .8 probably pulled one as two are in the same hole
46gr @ 2610fps .25
I didn't go faster as in my rifle next node is around 2780 (170 lockbase N540 load) and is near or at maximum. They did shoot very consistently.
Also tested 220gr ScenarL with similar results but N150 is only able to push them 2200fps region @ 41,8gr and 74mm COAL.
In the mean time i've got RS60 (Swiss Reloader powder which is made by Nitrochemie and should be the same as RL17) so next tests will be with that powder to see if i can get more acceptable speeds out of them. Pricing is not acceptable for claimed BC so i'll probably just play with them and never really use them seriously. 208 Amax and 140 HPBT from Hornady are cheaper and should perform better in my rifle (.308 and .260 barrels).
