He's done a ladder but still hasn't found pressure is all. It's been done with 5 shot groups and letting the barrel cool, bagged front and rear etc. Suppressor off after each string. I was just having a good hard think about; what am I missing here, what's my mate missing about this 243?.
@gimp
We had a look at a few twist rate guides and most of them said the howa with the 1 in 10 twist does up to 100gr? But could you please explain why it would do the targex and not the Sierra as their the same weight? I've never used or seen a targex pill so but are they quite different in ogive etc?
I think going forward he will try the speer 85gr btsp which we will start on this week.
Cheers for the replies folks it got me in particular a bit stumped is all!
@Husky1600#2 thank you for the kind offer. We will see how these Speers go and update you.
