Sako 75 Finnlight in 300 Win Mag I am shooting for the last 10 -11 years as my primary rifle. Different brass, once I shot 5 shots at 100 y in .626 inch I was done with development ( around 2012 ).
Federal 215 GM primers, IMR 4350 70 gr of powder with 180 gr Barnes TTSX for hunting, and 180 Hornady SST for plinking.( Start at least 10% lower)
No lead in my venison for the last 20 y or so.
This gun was a second-hand gun, came with a brake that was the laudest I ever used and I will never use it again.
I've got Sako S20 and got a factory Sako muzzle brake which is nice but does not fit my Finnlight.
Finnlight barrel is of smaller diameter.
BTW last season at Suffield I've shot Elk Cow at 538 y. Not bragging just an accurate gun lots of practice Good rangefinder and excellent Swarovski 5-25
scope with Ballistic Tip turret, Bipod, prone.I would not shoot beyond this
range.
Can't find this group with TTSX this is same point of impact with SST
