That being said, this powder is giving me lower SDs across the board compared to any of the other powders I've been using. figure is for a stock CM, without any of those modification or precautions being taken. If it is not -(pan weigh), dump it back in the hopper. Another trick is to observe the reading when you remove the pan, before dumping the powder into the case. Like the Acculab (just sold mine), it will be more consistent if powered though a UPS and left on all the time. If you wear a grounded anti-static wristband, you will prevent any drift due to static build-up, as the static charge will be dissipated each time you pick up the pan. The consistency of the CM is greatly improved if you add a reducer and re-tune it's parameters as described in the links above. SD is a function of consistency, no accuracy. I would not do it with Varget given those occasional blips in charge weight. I would not hesitate to use AR Comp on a progressive to make some short range rounds for practicing snap shots and shooting off-hand. However, the vast majority of charges fell on one particular weight, whereas they were pretty evenly distributed between the two center values with AR Comp. But with Varget, there was additional needed to the point that the mouth on the case I was using for the test was completely rounded inwards by the end of it.įor comparison, I also metered some H414. It really didn't take much to chomp and AR Comp kernel. There was also a noticeable difference in force required to cut a kernel. However, Some would occasionally go way higher, opening that up to an extreme spread of 0.8 gr. Most of the Varget charges were within 0.4 gr. Over a large number of throws (>30), all AR Comp charges fell within 0.4 gr. I've since tried dispensing them both in my LNL AP, in full progressive mode and AR Comp definitely meters better than Varget.
