Fed 215 primers and 111gr Retumbo with either Hornady 180 IB or 180 Barnes TSX both are just over 3400 fps with a 26" barrel and both loads drive tacks with my factory MK V.

Where did you start for your seating depth? Magazine length or specs in loading manual for oal?

Thanks,

If you want to shoot long range for that caliber use a bullet that will take advantage of its powder capacity, otherwise you may as well have a 300 WBY.

Start at 210 grs and more. I shoot 240 SMK's in my 30-378, 210 Berger's in my 300 WBY.

Start at around .030 off the lands and fine tune for accuracy. The Bergers will probably want to be closer.

Can you get that close to the lands with all the free bore, and still have a repeater?

Probably not.

Thank You, I'll work with the magazine length and see if I can find a seating depth and velocity the rifle likes.
