I have used 58 grn Vmax and 55 grn SBK in several of the 243's I have had over the years.
Both of the above bullets are perfect for a flat shooting and expand violently upon impact..

I do something very similar now in my 6.5 Creedmore - I run a 95 grn Vmax at 3400 fps just for foxing (and the odd unlucky crow that gets within range).

I have used several powders such as Varget , H414 , N140 , and RL15 in the 243 with the lighter pills.
Most recently I used H380 under a 55 grn SBK which gave 4055 fps and a lot of dead foxes. Barrel life wasn't in issue as I bought the Tikka 595 as a doner rifle ... but found it was still amazingly accurate.. so decided to speed up the death of the barrel .

My pet loads were as follows - both of these would group in the 0.3 - 0.5 MOA

46.8 grn Varget - 55 grn SBK COL 2.650 - 3815 fps

44.8 grn N140 - 58 grn Vmax COL 2.680 - 3680 fps

Obviously work up any load safely.



Merry Christmas
