I have a pair of the RCBS Uniflows, (set with one large & one small drum, micrometer adjustment.) I also have several Dillon's on my Dillon die sets.

I have the RCBS uniflow powder measure, large cylinder. I think Ill get the small(handgun) cylinder assembly or a whole another measure with the small What powder measure do you have/like? ***** Other than for sa short period after Fred Huntington sold RCBS to Leisure Group----memmory says late 1970’s----my experience with quality of the RCBS Uniflow measure ranks the instrument in very desirable category. The pistol drum works well for throwing tiny charges of fast powder. The Inflow was the first measure I bought, age 18. Still functions perfectly amor than a half century later. I put the Uniflow against the excellent Redding BR measure and finely machined Neil Jones Custom Products measures for top silhouette loads and 1,000 yard rifle loads----all loads thrown from measure, not weighed----and could not discern a difference. Two critical factors for throwing charges1) SOLID BENCH MOUNT. 2) CONSISTENT STROKE. Following an IHMSA match in New Braunfels, Texas, Jim Whitcomb and this shooter visitted the NRA Rifle Silhouette range. Going in cold, we each took four shots on a painted ram swinger @ 500 meters (547 yards). Whitcomb nestled into Creedmoor and, shooting his center-grip Wichita in 7mm IHMSA, centered 4x4 Sierra 168 BTHP in the chest, a 6-inch group. Next, this shooter got into Creedmoor with his Skip Talbot-built XP-100 7mm/308x1-3/4”, and with Ken Fryer----and a host of others----spotting, squeezed 4x4 Sierra 140 Spitzer Flat Base into the borrego’s brain pan, a 4-inch group. Remember a few scoffs from NRA rifle silhouetters as Jim Whitcomb got into Creedmoor.... Both pistols were loaded with IMR or Hodgdon 4895, with charges thrown from separate RCBS Uniflow measures with the large drum. Iron sights, both pistols. No scopes in handgun silhouette in those days* Wichita 7mm IHMS----Bo-Mar rear, post front. * XP-100 7mm/308x1-3/4”----Micro rear; .075-inch blade front. To give an idea of trajectory.... memory says, whereas my my Micro called for 8-clicks elevation @ 200 meters, I cranked up to 32-clicks for 500 meters. Also, boosted powder from IHMSA 28/H4895 to 33/H4895. Memory says primers were CCI BR-2. Brass framed from 7.62mm Twin Cities ’68 cases formed in RCBS dies, neck reamed and neck sized. Bullet seated into rifling. David Bradshaw

I like the Lyman 55, having used the one I have almost exclusively for the past 30 years. I have 2 of the RCBS Uniflo measures, one in a drawer, one in the original box in a cabinet. The Lyman is just so handy...

Well it can take several minutes, but once I have my Dillon 550 powder die set, it works beautifully with the dozen different powders I use. I get a new Dillon powder plug included with every new Dillon caliber conversion set I buy.
I pull the size pin so I can remove the case easily and measure the weight. Once correct, I quickly pull and throw the powder back in the hopper about ten times in a row. I measure one more time, and if still good; I start making rounds. Test again after every 50 rounds or so. Rarely see any movement.
I routinely stay well under a tenth of a grain variance either way. That has always seemed accurate enough for me to test for small groups. If I want 8.50gr Unique, I will accept a consistent 8.45gr or 8.55gr for that lot and mark the last round after measuring it.
In all candor, this is the only thrower I've used for the last ten years and so my experience is limited. But it doesn't seem broke, so I don't know why to fix it. Maybe other folks want even closer measures.

I like my Harrell but it won’t throw everything. I use a lot of H110 and it throws that extremely well. I used to have an RCBS years ago, it worked fine. I recently purchased an RCBS Chargemaster Lite and use it for extruded powders. My favorite measure is my Hornady on my LnL, it’s awesome. The only trouble is I don’t load everything on my LnL.

An old brown Redding on a solid table. I tend to throw charges and then use my AD FX120 and a power trickler. Anal, but my ammo is good. Using something like H110, I don't need to weigh each charge though.

Hey airborne, My scale is a GemPro 250 Precision. the published tolerance is .02 grains it's readout has .000 capability...................I only read .00 and even assume a variance with that. My Weigh SCGEMPRO250 250 GemPro 250 50g x 0.001g Scale www.walmart.com/ip/My-Weigh-SCGEMPRO250-250-GemPro-250-50g-x-0-001g-Scale/499335441$320 out of stock (same at Amazon and Ebay)(good luck finding one). I don't think I paid $150, but the memory is gone. I keep mine in a single, stable location and test/zero regularly. You also need to keep it very level. Scales don't like to be bumped, so shipping is problematic. DOA on any scale is not unusual. So, airborne, have I made a mistake on readouts from this scale? Is it a "precision science scale"? I've had it a dozen years as a powder scale. Prescut

Wow, that Gempro sure went up in price, paid less than 200 for mine. Darn fine scale though.
