A couple of 10-shot groups shot with the Tikka 7RM that I have for sale in the classifieds ()
FYI, I put a couple of clicks of right windage in it so that I don't shoot out the point of aim.
Load is 63.5 grains of 7828SSC, a CCI250, PPU brass, and 160 grain Nosler Partitions.
The shot on the extreme left of the second group was a called flyer, but you have to measure the whole system, including the shooter, right? All shots were fed from the factory mag.
A 20-round group shot from my 6.5 Creed. Barrel was chopped to 20" and threaded with a collar for use with a suppressor. Put an Atlasworx bolt handle on it and put it in a Stocky's VG stock.
Load is 43.0 grains of Staball 6.5, a CCI200 primer, in Starline brass, shooting a 140 grain Sierra TGK. I am getting 2603 fps with this load, so I think there may be room for a bit more speed. I have really just started messing around with this. I also have some 140 grain SSTs and some 143 grain ELDX bullets to play with.
