I use cci large rifle magnum and 92.5 of retumbo. Could Possibly do more just like it and stopped. Same hole at 100 and touching at 200 when I do my job.

cci's 250's are large rifle magnum, 200's are large rifle

I've always liked to use Federal 215 Gold Medal Match primers. They will get a lot of powder burned well and are very consistent most of the time. I have found where a rifle did not like them and switched to CCI 250's. Lost a little velocity (about 20fps) but the ES's shrunk down where I needed them.

I shoot the 208amax with 91grains of Retumbo lit by Fed215M or Winchester Magnum Primer.
