Thread: Fussy 243.

Gidday Team.

So thought I'd ask here as a close mate of mine whose a experienced reloader is having trouble with his 243.

Rifle is a howa match 243 24"
Arken 6-24 scope.
suppressor( the Swedish ones that DM sell)
B&C stock.

Projectile- 95gr TMK.
Brass- Norma.
Primer- Fed LR
Powder- Superformance.

Now these are seated 30 thou off the lands from memory( again not my rifle so don't quote me) but this thing will just not Group.

Done a ladder to find a node and then gone and grouped it from there.

Now this thing will not shoot.

Best group is 1 3/4". The hottest group still hasn't found any pressure and their doing 3212fps when I was last out with my mate at the range.

So what we've come to the conclusion of is this rifle does not like those projectiles for some reason unless we are missing something. So perhaps looking at trying a different pill. Like the speer 85gr btsp?

I have no experience with reloading 243s at all so I'm really out of my depth with the calibre.

The other thing yet to be done is to try some factory ammo to see if it's a rifle issue( which we highly doubt but am happy to be proven wrong).

All bases, screws etc are torqued to spec.

The thing that baffles me is the TMK is my go to bullet for 7 and 30 cal and I'm yet to see one that won't shoot it albeit in the said calibres from first hand experience so I'm not sure what the go is with this .243? And help would be highly appreciated
