    Does anyone have any experience with something like the RCBS Chargemaster?

    I like the idea of it but just want to get some feedback before buying one. I already have an RCBS electronic scale so it looks like it would be really easy to just add the charge master.

    I'm thinking it would be a lot more convenient than manually dipping. I get tired of scooping and getting close and then trickling up or scraping some out with the dipper to go lower.

    Well, a standard powder measure will get you close enough for Gobber-Mint work about 10 times faster then a scoop and trickling, and dipping some out when your trickle trickles too much.

    Truth be known, there is absolutely no reason a 50 grain rifle charge has to be exactly 50.0 grains and not 49.9 or 50.1 grains.

    You or your rifle can't shoot well enough to measure the difference in group size.

    And if you are waiting on charges now, you will be waiting longer with an electronic powder measure.

    Listen mister...when I want 50....IIIIII want 50!

    I suffer from OCRRD (Obsessive Compulsive Rifle Reloading Disorder) It's the only area in my life where I exhibit the behavior...I want my rifle charges to be exactly spot on. It's a weakness...and one that I unfortunately have no control over.

    With pistols I'll let a tenth of a grain or two slide if it's within safety tolerances...but the rifles are held to an absurdly strict standard. I tolerate no excuses from them. :D

    Oh...and thanks for the link! That will be some good reading.

    I have one that I bought for .243 and 22-250 when going out P-dogging. I had 1000 rounds to load then and reload back at camp. It worked good, but was a bit slow. I usually seated the bullet in the previous case as the next one was dumping. Wasn't about accuracy, just didn't have a progressive back then. I wouldn't buy one now. I'll use the regular powder dispenser, much, much faster.

    I thought about buying a Hornady dispenser with a micrometer insert, then having it dump though a funnel onto my scale pan.

    That might be cheaper and faster.

    RC Model is right you know. The powder measures your talking about use the same electronic scale that you buy as a stand alone. They are rated at +or - .1 of a grain the same as the beam scales are.

    If you are that obsessed you better stick to beam scales and digging out .01gr. turds out of your rifle loads.

    What you said about using a powder measure dumping into a beamscale pan would be the cheapest and fastest for what you want to do.

    That is the one universal truth I know.

    I think the sun will come up tomorrow...I suppose gravity will be in effect...but I KNOW RC is always right.

    I have the RCBS Chargemaster and it is accurate but on the slow side. I still use my beam scale most of the time and good quality powder measure. I would not buy again as money could be used for something I would use more often.

    I have the Pact dispenser and scale similar to the RCBS Chargemaster. I use it when I am working up loads as it is faster than trickling powder and is faster than fooling with a powder measure when changing charge levels.

    A few buttons to reprogram the dispenser and a new charge weight is being measured.

    Once the load is developed, I use a regular powder measure. The programmable dispenser is too slow.

    And RCmodel has great information as usual.

    I use mine for 70% of my loading. Thousands of rounds through it. Works great on stick powders that don't throw accurate enough on other measures.

    If it broke, I would most likely buy another one.

    I have a Smart Reloader that drops the next charge & waits on me while I'm still setting the bullet.

    I find it hard to believe the RCBS can't be adjusted to drop a faster load.

    Mine work great and it has great accuracy.

    I charge and load 223 and 7mm TCU progressively just like handgun ammo with my Hornady powder dispenser on my Lock N Load press.....it's pretty much dead nuts after the powder is settled good in the hopper. I never use the baffle it came with.

    The chargemaster is probably the best thing I've EVER bought when it comes to reloading.

    Well, might be right behind that powered case trimmer I bought. That's a thumb-saving SOB there...

    It can. You can adjust the speed thresholds, they are programmable. It takes < 20 seconds to weigh out 70 grains for my 300 win mag loads, about 15 seconds for 8mm. I barely have time to seat a bullet and put it in a box, before the next charge is done.

    The McDonald's straw trick works great for preventing overthrows. I haven't had ANY overthrows since I stuck a straw in the end of mine. Keeps a big turd from falling out and spoiling your fun when it gets towards the end.

    I figured it could. Mine has 3 does it slow down at set percent then trickles at the next setting.

    I hear RCBS even suggest the straw. I wonder why they don't just make it part of there design?

    I dunno, you'd figure by now they'd just throw it in the box.

    I didn't know about this for the first several years I used the thing. Was constantly pulling overthrows out.

    I started on a beam scale, then went with an electric scale, still throwing by volume and trickling in.

    I like having the scale toss the charge for me, much better. Lets me shave time off because I can seat the bullet in, wipe the lube off the casing, box the ammo, etc while it's throwing the load. Even have time to scribble labels - but it takes about 6 cartridges to get one all the way filled in.

    I don't use the electric scale for pistol ammo, or bulk plinking 223, I throw that stuff by volume (either on the Dillon or, if I'm doing a small batch by hand, or something I'm not set up for with the Dillon, like 45 colt, with the Lyman measure I have on the bench.)
