I noticed when chambering the Kreiger 8 twist it had a tighter than usual bore had to order the correct bushing. First 5 down the tube and it pierced primer. Would it help to have the bolt bushed ? Or should I just back it off a little . 75 eldm h 4350. 42.5 gr

Maybe back it off 20% and work up, but don't take my word for it. Peterson Cartridge thinks that 38.2gr of H4350 is at about 62ksi. You're well in excess of that. See Load #1:

My personal 22CM 77gn Nosler CC, 42.2gns H4350, CCI200, 3508fps. This was prior to the Peterson info above being released rest assured I'm not going back there again.

It groups well for the first 5 down the tube. I'll back it down some. I better double check something for some reason I wrote down 42.8....... old age is getting to me. I sure hope I didn't put that much in there

Nice group. If the brass, receiver and throat will hold up to the pressure, then bushing the bolt might allow the primers to remain intact. Put it over a chrony, I bet it's a laserbeam and absolute hell on coyotes. I'd avoid shooting that load in Texas Summers though.
