I load for 2. IMR4350 worked very well with 168 TSX bullets. 4895 worked very well with the 180s.
Have not tried 414 but have some on hand.
I stopped loading for one as the owner just had it rebarreled with a Lilja tube, so I'll be starting from scratch.
One bullet he wants to try is the 180 AB. Not sure what else he wants to try yet.
The second one belongs to my brother. He had me work up some 180 btips that did well with 4350.
