Hello guys,
I´m a Krautshooter circling around exactly this subject, with a Tikka T3x CTR 24" barrel. Found this topic by googling around and it was dead-on.
After testing 8 bullets I got stuck with the 147 Hornady ELD Match and the 139 Lapua Scenar, which gave me the best precision so far.
Not already at that point where I want to be, but getting near.
Tested 3 powders also, the N150 (which I had on hands because of my old .30-06), the RS 60 (which was a bit to fast) and am gambling around with the RS 62 right now.
Primers are Remington LR.
My goal is to get as fast as possible being as accurate as possible.
The 139 Lapua has a V0 of 2800 fps and the 147 Hornady is around 2680 fps with the RS 62, above those velocities first pressure marks appear, so I´ve been settling there.
Precision is around 0.5 MOA or slightly above 0.5 MOA.
I´ve read inhere, that CCI primers are recommended. Are they more consistent?
I also thought about testing another powder to maybe gain some tighter groups or/and a bit more velocity.
Because of availability I would prefer Eurpean powders, RS or VV.
Has anyone tried the RS 70 or the N160 in the 6.5 CM?
Any response, info or help is appreciated.
Cheers from the Black Forest,
Jay
