Which Powder Measure
 

I am new to whisper loading but have already figured out that weighing individual charges is way to time consuming.

What powder measures do the experts reccomend for weighing charges from 8-12 grains?

I was looking at the Redding and the Forrester?

I dip and weigh all mine, it doesn't seem that time consuming :tongue:

Does anybody out there use a powder measure to throw charges?

the RCBS charge master 1500 gets it done for me.

I think with the small charges in the 300 whisper it's so sensitive to beginng off by .1 to .2 of a grain you might want to test any powder measure you try and do this with - I have RCBS thower and it's not accurate enought I have lee disk measure and it's not that close, I have Dillon measure but it's also not that consistant. That's why I would throw or dip to get close and trickle to get exact :wink: I do throw charges for other cases of similar volume where it isn't as critical in application (like 357mag or 44 mag or 7.62x39)
but I'm not trying to thread the bullets into the same hole with those rifles.

.2 of grain variation min my gun will make a 2.5 MOA gun instead of under 1 MOA in my gun. Heck 2 extra cokes in me will do it too. :frown:

The forrster, redding, hornady etc... will all be equal. They will all allow you to set a specific volume of powder to be thrown. The problem you have when weighing 8-12 gr is not going to specifically be with the measurer. It's just a problem with small volume. A ball powder will meter the best but will still not be good enough (as previously stated) to use for consistant and accurate sub sonic loads. "Throwing" supersonic loads is fine and can produce good accuracy, but the subs WILL require extra attention to detail. The only way to make it easier on yourself is to buy Cor Bon ammo. Not cheap but..... easy.

Harrell's Precision

works excellent for pistol and small rifle cartridges, very accurate....It is on the high end for powder dumps.......Not trying to be a salesman for Harrell's but they are fast and accurate, two words that don't usually go together.....the subs seem to be very charge critical to keep the vertical stringing to a minimum....if I'm going to load 8 or 10 rounds to test I just use the scale....if loading for a normal range day of 200 or 300 rounds I use the Harrell and don't have to worry about repeatability, saves a lot of time....the last regional hunter class match I went to I would guess that over 75% of the competitors there were using Harrell's dumps, including the winner :smile:

from their web site: "It IS the most accurate small charge powder measure ever produced. Each click is .03 grains, that's 1/3 of 1/10 grain per click."

Not saying the Harrell is not a fine measurer but..... The real problem is consistancy. You need to make sure you keep the same amount of powder in the hopper and you need to make sure that you use the exact same amount of force every time you throw the handle.

These two factors alone will vary the amount of packing that occurs in the opening that the powder is going into. Since the amount of powder being thrown is so small, these variables are more critical. Consistacy takes time and patience.

I use a Lyman 1200 digital powder scale and dispenser system and am happy with it. When I am only loading a few rounds I use the dip and weigh because it is a little hassel to empty the Lyman system. Other wise it work great.

My hornady with a pistol rotor throws 8-10gr of H110 exact. I have never noticed any variation.

I use the rifle rotor for supersonic loads and have no problems there either.
