I upraded my .222 to a lovely Sako S491 which in theory has the same 1:14" twist barrel as the BRNO fox it replaces
I initially had a quick plink with a cheap spare scope and some factory ammo and some of the 60gr SP and 52gr Amax home loads I had for the BRNO
not an exhaustive test but....
50g Sako factory was average at around 1-1.5" groups
55gr Sako Factory was worse at around 2-3"
My homeloads looked like they could be better than that but I was stringing them vertically which I finally put down to a reparallaxed (air rifle range!) scope giving massive POA shift on the slightest movement up or down
New scope fitted and a box full of home loads across the charge range for 60gr Amax and 52gr Amax
I tried the same charge as worked in the BRNO on the 60gr (20.6gr N133) first just in case it was tight without the need to play around
Touching holes with the odd one off to the side by 1/4-1/2"
Aslo shot another group at the end of the AMax charges to confirm. All good. Identical
Leave that one well alone!!
All done for a deer load.
Started the Amax loads at 22gr and went up to 23.2gr in 0.2gr increments (VV indicates a range of 21.1-23.1gr of N133)
Shocking. truly shocking with no apparent indication of any nodes in that range
When I say shocking I mean 5-7" of shocking!!!
Am going to see if the lower charge of below 22gr works but will be surprised if they suddenly shrink within the lower level of a 0.9gr range!
Am a bit gutted as they are normally a cracking bullet and were deadly accurate in the BRNO (added to the fact I have fecking hundreds of them from years of stock piling!!
Just wondering if anyone else has them working in a 1:14" .222 Sako or Tikka barrel ?
(.223 doesnt count as they are faster twist)
