This was a baited hunt on the Fort Apache reservation. The day starts driving into town and having breakfast at great breakfast with the outfitter and guide. Then back to camp and load bait onto trucks. Then the guide and I went out to bait and check cameras to see what activity was going...
I have an old IMR reloading sheet that show 33.5 gr. of 4198 giving 2350 or so FPS. This is listed as max I have read that 30 gr. is a very nice load..
This is with a 180 gr. bullet. Should be just as nice with a 170.
I would try two things. Start with your most accurate load and keep seating the bullet deeper. In my 270 it likes a lot of jump. I would also stop cleaning and see if it shoots better as you get some fouling. I have several that shoot great when dirty.
