I use IMR 3031 in mine and got some very good results around 35 grains........I also got very good results at 37 grains.....using a 200 grain Remington Core-lokt.......
I have found the band tightness, especially the one on the muzzle needs to be loose......on my rifle, the tighter I get it the worse it shoots....
My rifle shoot about 1" at fifty yards with a fixed 4X scope.......and about 2 and a half inches at 100......not a tack driver but more than adequate for deer and bear in the hardwoods.......
I plan to try some reloader-7 and IMR 4064 in the future, but it hasn't been a priority.........and probably won't for awhile.......
Got a new, used, Remington 700 in 30.06 that will get my attention next.........
