The brew
RP brass
federal210/CCI200 primer
53.5grains of 2209
130 grain Sierra Gameking
cartridge overall length 3.260"
24 inch barrel

The loads that did get recorded are below
56 grains (max load in speer manual) = 3050 fps
55.5 grains = 2974 fps
55.0 grains = 2950 fps

Why the mix of primers? Stick with one type, otherwise its a variable that changes everything.

The cci ones are what I am going over to @dogmatix as vern wilson down the road from me has CCI one of the resons being that I have had trouble getting federal primers and the only place that has them in hamilton is H&F with the guy here I can give the missus the money and send her down the road while I am at work to get me my primers when I need them the initial test I did a couple of weeks ago with that brew used federal my second test of that brew had CCI so I guess I was lucky that it did not alter anything for me
