I am trying to get the 212 ELDX's to run out of my Weatherby Accuguard. Using H1000, the load I tried today is 77.1 grains. I seem to be getting a lot of split groups...two or three in one hole, two more in another hole...Ran them over a chrony...HORRIBLE ES and SD. Velocity was only 2825 on average. Not sure what to think, TBH, I'm not a great handloader, probably because I despise doing it. I can't increase distance to lands....it is a mile away already and I am box limited, so I can't get close...I am thinking that is the reason for the poor performance. Oddly, when I worked up to this load, had no issue with a sticky bolt on this load, nor the next .5 grains higher (book max), but some from today had some resistance on bolt lift. So maybe my scale is the problem. I run the RCBS chargemaster, double check each load on a gempro. But that thing drifts like crazy, makes me nuts. Still, it should definitely be withing .1 grains, I am trying to get it to be within the .02 grains of the scale's MOE. Hope it's not the powder, just bought a whole bunch of it from the same lot based on initial testing, which looked very promising. Anyway, any thoughts would be helpful. Maybe have to move back to the ELDX 200 grainer so I can get closer to the lands. Might try the new Edge TLR.
