New 223 Load Development

[Back_Trail]

I’m about to start working up a new .223 load in my Tikka with a 1:8 twist and a 22.4-inch barrel. I’m looking at the 69-grain Sierra TMK with H4895. Has anyone used this combination?

Yep, plenty, you should probably start at 24.5 and finish before 25.
Probably the easiest way to get good accuracy from a Tikka.
Load to max magazine length.
