I'm thinking of trying CCI Magnum primers in my 6XC. I have the first gen brass with less case cap. than either the 2nd or third generation brass.
I'm using 38grs of H-4350 with Fed 210 primers an this seems to be the max load but the gun won't shoot anything less. With the 38grs I am getting ejector marks on a few cases but if I back it down a half grain my groups open up.
My problem is I'm getting inconsistant readings on the cronograph. I can shoot a group an get a one or two foot variation between three rounds then have one jump nearly 50ft per sec faster.
The gun is also inconsistant when shooting groups. It will shoot the 38gr load into the .3s then all of a sudden I get a .6 group!!! I have weighed all the brass an neck turned it, if there is a difference in the brass I don't know what it is.
Someone suggested I use CCI magnum primers for better ignition but I know this will probably create more pressue also. Should I back my load down a grain or so when using the mag primers?? David Tubb thought maybe drilling the primer hole to .080 might help also. Anyone ever tried this??? Thanks guys!!!!!
