Hi,
It's getting deep in here again...
Beam scales, or balances as some have corrected me in the past, depend simply on gravity, arguably the most consistent force we deal with every day. The job of our scale, no matter how big, small, simple or complex, is to measure the effect of that gravity on a mass and give us a result of that interaction expressed as a weight, in one of several kinds of units, which in the reloader's case is the one we call grains. One can purchase check weights which trace back to THE official standards bureaus, and they don't change. So if one prefers a beam scale, as I do, and it checks out dead nuts against the check weights, as mine do (and the oldest, an RCBS 5-0-5 has been doing for 40+ years), it's done its job, and that's MORE than good enough!
Now, many people like the electronic scales. That's fine, as long as one recognizes their vagaries and can work within them. Yes, they can be convenient! Yes, they are quicker for certain kinds of jobs! Despite the big differential in retail prices, they are probably cheaper to have Wat Yu Way put together in a Chinese sweatshop than a good beam model. However they can be, and often are, inconsistent due to a variety of influences, both internal and external, far more so than beam models. That said, a tenth of a grain is a tenth of a grain, no matter how it's weighed, so, no, they are not any more accurate nor precise than beam models, and in my experience, often less sensitive. (Sensitivity being drfined sd that quality of being able to detect a change in the tool's reading at the very lowest levels, something our consumer grade electronics are often deficient at doing. Yet it's probably our most important consideration when trickling!) If their shortcomings don't bother you, get one and use it! If you wish to spend $300 to do a $100 job, it's your money and your choice how to spend it.
But please quit telling us they're "better" than beam scales. They're NOT. They do the same job, in a different way. Simple as that, and most of our reloading tasks fall under that exact same heading. There's a reason so many companies make reloading equipment, and no two of them do it exactly like the next guy... EVERYBODY has his/her idea of what's best, and they're probably correct. For them...

No "Match" shooter I know of, including myself, trickles up charges, because it has been found to basically not matter. In a "Match" load you are only concerned about two things, grouping and velocity spreads

I believe I made that clear in my first post. Accuracy and velocity spread is what matters and the simple fact is a tenth of a grain doesn't change that, plus my Chargemaster IS accurate within a tenth of a grain, so trickling gains me nothing. I DO shoot matches, I know many match shooters, we have a large group of them here. Not ONE trickles up charges. My velocity spreads between 10 shots strings are VERY small, so whatever I am doing works and one of those things is throwing every charge with this machine, along with meticulous case prep and bullet selection.Kevin said:No "Match" shooter I know of, including myself, trickles up charges, because it has been found to basically not matter.

I would definitely disagree with this statement. A trickle up charge from bullet to bullet will be more consistent. How can that NOT matter? Don't you want each bullet for a match to be as equal as possible? In a match IF you are concerned with velocity, as you say (and I agree) shouldn't you be concerned with how much powder is in the load? Yes, down to the tenth, IF you want consistency from bullet to bullet.
And this....???

Sorry, but the RCBS 10-10 scale does do a very good job of measuring in the tenths of a grain. I bought this scale years ago because of these measuring capabilities.
If you would like I can post some close up pictures of the scales tomorrow.
Yes sir it is. I have some rifles that have special chambers. Meaning myself and my Smith, had the reamer made like WE wanted it. After you fireform some brass, you sent that to Whidden Gunworks, Warner Tool, whoever and have custom dies reamed to your brass. Sometimes it does what you want, sometimes it doesn't. If not, you set the barrel back, make another reamer and try it again. The quest for ultimate accuracy never ends. Just depends on how far you want to go and nobody has EVER gotten it perfect. Even rail guns that take the shooter completely out of the picture, don't put 10 shots in one hole at extended range. Because no gun and no round will EVER be perfect.TitanX said:The most surprising thing I've learned is that you can have individual dies custom made to match the chamber of a SINGLE individual rifle.
Man, that's custom.
The only way to be certain each and every powder charge in a batch of cartridges weighs the same is to carefully weigh them on a scale. Even so, many handloaders have discovered that a small variation in powder charge weight usually has little to no effect on accuracy out to the maximum distances they shoot, and for that reason they save time by measuring charges rather than weighing them.
In conventional benchrest competition, where targets are placed at 100 and 200 yards, top-ranked shooters customarily average less than 1/4 m.o.a. accuracy. They use the same dozen or so carefully prepared cases for each rifle and reload them between relays during a match.
Instead of weighing powder charges, they use precision-built measures to throw them. Ask one of those guys how much Vihtavuori N130 he is shooting in his 6mm PPC, and rather than giving an answer in grains, he will likely tell you what setting he uses on his Harrell or Culver powder measure.
Back when I bumped off a lot more prairie dogs each summer than I do today, I decided to compare the accuracy of ammunition prepared with weighed powder charges and those thrown by the measure of a progressive press. Several different powders and bullets were loaded in the .223 Remington. I shot the ammo in two custom rifles in .223 Remington, both capable of shooting inside half an inch at 100 yards. I also tried the loads in my rail gun.
Groups fired out to 500 yards revealed no difference in accuracy between weighed and measured charges. Some of the ammo loaded on the progressive press was actually a bit more accurate in the rail gun, but I chalked that up to fluke rather than uniformity differences in how powder charges were dispensed.
Benchrest shooters and varminters shoot small cartridges that burn relatively small powder charges, but measuring powder for cartridges with bigger appetites can work equally well.
Before a rifle built by Kenny Jarrett is shipped to a customer, it must consistently shoot three bullets inside half an inch at 100 yards. I used to visit his shop quite often and, just for the fun of it, occasionally accuracy-tested rifles for him. The powder charges of all test ammunition used in Jarrett’s shop are thrown by RCBS and Redding measures. A scale is used, but only when adjusting the measures to throw the desired charge weight. Same goes for his line of custom ammunition.
For most of the reloading most of us do, powder measures available from RCBS, Lyman, Lee, Hornady and Redding are precise enough. Benchrest shooters usually go for precision-machined units like the Micro-Measure from Neal Jones as well as the Harrell and RFD/R from Sinclair International.
Benchrest competitors sometimes tweak the loads they are shooting between relays, and the custom measures they use have more precise repeatability of adjustment than some mass-produced measures. I started using a Jones measure during my benchrest shooting days and continue to use it today. With many powders it is not a whole lot better than high-quality measures available from other sources, but it does operate more smoothly and throws charges of large-grained powders a bit more consistently.
How a measure is used is extremely important. To throw charges with minimum variation, it has to be operated exactly the same for each charge of powder. If you bounce the handle hard against its stops on one charge and then operate it softly on the next, the two charges will likely vary more in weight than if the handle is operated exactly the same both times.
I consider a charge weight variation of 0.3 grain acceptable in the larger cartridges such as .30-06 and up, but a good measure, operated properly and filled with a smooth-flowing powder, should hold that to no more than 0.1 grain. When measuring extremely heavy charges, consistency will improve with some measures when two half-charges are thrown into the case rather than one whole charge. In other words, the handle is operated twice on a 40-grain setting rather than once on an 80-grain setting.
Finely granulated powders meter through any measure more accurately than coarser powders. This is why benchrest shooters use either ball powders or fine-grained stick powders such as Vihtavuori N130 and IMR-8208 XBR. Same goes for varmint cartridges.
Any time I don’t use a ball powder such as W748 or A-2015 in the .223 Remington, I’ll use a small-grain stick powder with Benchmark and V-N135. If H4831 and IMR-7828 are your favorites for the .270 Winchester, finer-granulated versions of those two powders designated H4831SC (short cut) and IMR-7828SSC (super short cut) flow through measures more uniformly than the originals and their burn rates are the same.
Digital dispensing systems capable of automatically measuring and weighing powder charges are available from Lyman, RCBS, Hornady and PACT. After the machine is programmed for the desired charge weight, a push on its start button or placing the pan on the digital scale causes it to trickle powder from a reservoir into the pan. In addition to being more precise with large-granule powders than a standard measure, it totally eliminates operator inconsistency in throwing charges.
To reach peak efficiency with one you may need to modify your loading sequence a bit. When using a standard measure, I charge all cases with powder before moving on to bullet-seating. Depending on the size of the charge being dispensed, a digital machine can take anywhere from five to 30 seconds to get its job done, so seating a bullet on a charged case while the machine is dispensing powder for the next one speeds up the operation a bit.The above is a story from Layne Simpson...........
I have a cheap Lee not-so 'Perfect Powder Measure' that does real well with extruded rifle powders like Varget and H4895, and also does fairly well with coarse flake powder like Blue Dot or Universal, I think because it has a flexible wiper built in. Fine grain powder spills out of the sides of the measure.TitanX said:gtxmonte said:Jimbo mentioned measures and that's correct. Some are better with ball, than they are stick and flake and vice versa applies as well. I have measures from Lyman, RCBS, Redding and Harrell, multiples of some
As a newbie, I'd appreciate learning what measures you use for what types of powder.
I have the Hornady measure that came with the Lock n Load AP, but am trying to decide what to get for use with my Rock Chucker (rifle reloads and other low volume use).
