QL request - 243

smoothie25 · Oct 24, 2016

Could someone run a quickload for me? Working on a load for a 243 I just bought.

70gr nosler varmageddon .334 BC
H4350
COL 2.680"
22in barrel

Nor sure what my actual case capacity is. Nosler book says 50.8gr

Also, would be interested in anyone's experience with this bullet.

Thanks in advance!!!

If I missed something on the Quickload let me know and I can re-run it.

I have used this bullet and also the 70gn BT. I hunted and shot Coyotes with the BT but not the Varm bullet yet. Looking forward to it though.
