Evening fella's I've got a "thing" going on a I'm scratching my head! wondering if any of you have run into this before so thought I'd just ask and see if you have any thoughts.
New rifle and working up loads, won't get into the caliber yada yada but the other day my brother and I had the rifle out for it's first run and used his Magneeto speed crony and we were getting some rather impressive velocities!
80.5 = 3036fps
81.0 = 3049fps
81.5 = 3065fps
I'm loading rather long with this caliber and well wanted to do some more testing as I thought the readings were a touch flakey! but hey stranger things have happened so I did another test with the same loads but this time I used my CED M2 crony and here's what I found,
80.5 = 2931fps
81.0 = 2967fps
81.5 = 2998fps
Now I've been using the CED M2 for many years and haven't had any issues when working up drop charts but I've got to admit now that I'm a touch confused as there is a good amount of difference between the two! none of the loads showed pressure sign BUT from what I've read I should be seeing some pressure around the 3050fps mark but which data do I use? I don't have another crony that I can use to verify and it's going to be a month before I can get to the range with enough distance to verify so I'm torn on what to do now and just wondering if any of you have run into this before and what you did? I appreciate any direction or thoughts but I'm about to the point of pulling my hair out trying to wrap my head around this one and none of the guys around here that I know have run into this issue so the reason I ask the folks of the inter webs. Thanks in advance!
