Re: 6.5 grendel bolt action
I've got a Sako Vixen in 6.5 Grendel.
24" Lilja barrel, and Hightech stock.
I use it for hunting and longrange/BR. At a 550yard competition in the unlimited-class I fired a 10 round group of 12.25mm, or 4.82 inches.
I still have the target.
I use 130grs Norma Golden Target and 130grs Swift Scirocco II,
with 26.5grs of VV N140 in Lapua brass and remington primers.
V0 = 2300 fps. I'm not chasing a hot load and flat trajectory,
if so I would've gone with 123grs Scenar and 123grs A-max.
As of now, with the Norma/Scirocco the best 4-shot group has been 0.2moa,
and it averages 0.5-0.7moa. I don't wanna mess with other loads as long as I get that kind of accuracy out of it.
When I'm done with the Norma/Sciroccos I have left I probably will try out some 123grs stuff and some hotter loads though.
I think its worth to mention that the Scirocco II's show clear signs of tumbling at 550 yards, while the Norma Golden Target does not. I don't know why that is, they both have the same v0.
It's deadly accurate out to 600 yards, however there is a real difference between 600 yards and 650 and onwards. After 600 yards it's not nearly as consistent as up to and including 600.
I also use a telescopic and modular Atec CTM-4 suppressor. It comes with four modules, I only use two. When I've burnt through the two that are on now, I'll replace with the two I've put away.
Here it is, by the way:
