Hello Zaitsev,

yes, I also noticed the heavier bullets in Norma ammunition line (404 with 450grs!)

But I will try the "heavy bullet solution" in a small caliber:
a gunsmith modified a Sako rifle for me into 6x47 Swiss Match.
I will use this rifle for opening season on small roe deer (yearlings).

I tested due to the 1:7" twist the heavier bullets:
100grs Speer Grand Slam
95grs Nosler Ballstic Tip
95grs Nosler Partition
95grs Hornady A-Max (only for Precision)
95grs Hornady SST
85grs Sierra HPBT Gameking
85grs Barnes TSX

I think I will try the Hornady SST, they seem to be a little harder than Ballistic Tips.
I will, of course, try to place the shot closely behind the front leg.

Can you please provide results on your gun and reloading?
I think the 6XC and 6x47 SM are close relatives. (I measured 820 m/s with 95grs bullets, of course no max.)

best regards and good shooting!
Rolf
