What are you guys using to measure out varget and similar cylindrical powders?
RCBS Chargemaster? |
|
My Chargemaster doesn't behave that well with Varget. Out of say 50 loads, 5 will be over by a grain. I use the drinking straw trick and it flows well but it always goes over. It's not a big deal because I verify the weight before I drop it but that means I have to reweigh 10% of my loads. I don't mind using it for .308 since I take my time with those rounds, for the sake of maxing out their potential, but for 223 I bought some TAC and IMR XBR8208. I've used the TAC and it meters like water. I haven't tried the IMR yet but reports (from here) state it meters much better than Varget and from looking at the granules (short extruded grains), it is apparent why it meters better. |

I'm hoping you mean by 0.1 grain! (Otherwise, you're saying it's acceptable to be off by 0.9 grain). |

Quoted: It's been a while since I've made those rounds so I don't remember if it was 0.1 or 1.0. I was working through 5 different loads, incrementally, so the difference might have been (for example) 23.9 vs. 24. All I know is I watch the scale to make sure it's not over or under.

PPM here. It gets within 0.10 grain on progressive setup and with SD less than 25 ft/sec, plenty good for all work. One issue with Varget is the very light graphite coating compared to IMRs which appear solid black. This reduces the flow. Coating the measure with graphite seems to help. |

Iv'e bee using my chargemaster for about 9 months now with great results using Varget, after I did the straw trick, and re-programmed it.
I can't remember the programming, but for the straw trick, I used a heavy drinking cup straw instead of a McDonalds one, and it throws 99-98 accurate loads out of a 100 now with Varget. The straw I used was from one of those heavy plastic drinking cups with the hard plastic straw the goes through a lid with a gasket, you get at K-mart or Walmart. I cut a 1/2" piece off the straw, and stick it half in, and half out of the dispenser tube. |
