I have 200 Sierra 200 grainers coming this week. You know at 2400fps this is treading on the heels of the great 348 and 358 Winchesters! Back from an amazing sheep hunt and back out again next week but I spent some time yesterday testing the 235 Speer lathed back to 225 grain for a bigger lead exposure. Turns out to not make a difference I thought it might and I think 229 grains is the best modification. Also tries starline brass. Good brass but at 10 grains heavier than Winchester it has less capacity. Got over 2000fps with my standard load with 255 grain bullets. Need to cut back about 1.5 grains of powder when using starline.

Sheep hunt (but not using a lever, even though I got close enough to use the 375) https://www.youtube.com/watch?v=7LVZW9sPg0Y&t=22s
