    Ocw confusion

    I dont have any pressure signs with either powder and was also wondering about the next node. I haven't checked velocities yet. A friend has a chrono, so that's my next step. I think I'll chrono the 39.1, see what it does at 600 yards and go from there.

    Ocw confusion

    I think you looked at the first IMR test in the middle. The H4350 is the bottom and I did switch to .3gr increments for both tests this time. ?

    Ocw confusion

    Two more tests today, this time at 200yards..... Pretty sure my rifle doesn't like the IMR. With these tests I adjusted the COAL for a .002 jump, all componants were the same as before. Top row is the IMR4350 and the bottom is the H4350. Looks to me the IMR would run at 41.7gr and the H at...

    OCW and temperature

    Brain fart..... changing temps will technically move the poi to the next higher or lower load.....hence the point of the OCW testing. Guess I just had to think a little harder.

    OCW and temperature

    Understandable on both points. My question is since the temp can make a load shoot "lighter" effectively changing barrel "wave", with warmer temps the poi will shift as barrel "wave" changes, but grouping should stay relative?

    OCW and temperature

    Even when using more temperature stable powders, wouldn't it be a better idea to run OCW testing at your average shooting temperature? I want to run another group of loads, but the 30 degree temp has me hesitant. With the low temp, would for instance a 40.8gr load shoot more like a 40.2gr load...

    Ocw confusion

    Thanks for the info guys. The POI had me confused as it didn't show much of a shift. I've loaded up another round starting at 41.5 and went up in .2 increments. I'll see what happens when the snow clears a little.

    Ocw confusion

    6.5 Creedmoor 22" Hornady once fired CCI B2 140gr ELD Match IMR4350 OAL 2.80 100yd round robin 58 degrees I'm not sure where to go from here. Most OCW tests I've seen have a more definite pattern of dispersion. I didn't have access to a chrono at the time I shot this. The IMR may not be ideal...
