ohhhhhhh.
My first solution
ask someone else to sight in the 44 grain load.
Second is to fire your closest to 42 grain load.
Soon as you fire extract the brass. If the bolt lift requires more than routine effort you are too hot.
Next, examine the primer. If the primer is cratered, well, I don't mind cratered primers so much but they are your very first indication of overpressure.
Take the case and bang the side of the head against something solid as if you were trying to knock the primer out. If your primer falls out, you are over pressure no more talk unload everything 42 and over. Start with the min load and work up. Eyeball the case neck. You are looking for a split. unlikely, but look anyway.
Now if everything is routine normal load and fire for functionality one 44 round. simply point the rifle downrange and fire. Then repeat the process above.
I think you might see a little bolt lift effort with the 44 and for sure a cratered primer. If you see what is called an ejector mark on the headstamp area of the brass, you are firing a hot round. I get these all the time, it is an indication you are overpressure a bit and you should maybe not fire anything hotter.
Take a look at a recent Mr. B post about 6.5 CM and H4350. This is a hot load. I am agonna give it a go because accuracy wins in my book so long as I retain my appendages and other pieces-parts. Being a tad over doesn't faze me so long as the bolt lift thing stays away.
Seems to me the entire .284 family has above average accuracy and you can load your own to milk every last bit possible. Its what makes this hobby so satisfying.
Stay healthy
