Hello,

What kind of powder measures are you guys using. I am using a Lee Perfect powder measure and its throwing all kinds of crazy measures. I try to get 42 grains and it will throw anywhere from 41 to 42.3 grains. I end up having to re-measure each and every load on my scale. Its a real pain.

Honestly, I still hand weigh every charge for rifles most of the time on the Pact Digital Precision Pro scale.

When I'm loading a plinking load were accuracy is not an issue, I will use a ball powder, and then use a charge weight that is a full grain below max. Then I'll set my RCBS Uniflow for that weight and just throw them down. No problems with this route.

Handgun loads I will throw with the Uniflow and weigh each throw on the RCBS 505. As long as it's close to the tick mark, I'll use it.

I use a Lee quite a bit and the reliability really depends on the powder you're using. 2400 is my most used powder and have no problems with it.

What kind of powder are you throwing, 4064?

I use a Harrell's powder measure myself. It throws medium stick powder like Varget, 4895 and RL15 to within 0.3 grains.

It's bling, but I have my vices.

Im using varget. I was pretty suprised at the differences it was throwing. Ive heard pretty good things about that measure.

Extruded powders can be harder to throw with most measures.

I'm a big fan of most LEE's tools, but I don't like that measure. I sent it back the day it arrived.

Out of my Lyman, Redding, and RCBS, the RCBS uniflow is my favorite.. ;)

I use a Harrel and typically get 0.2grs. Every now and then, it'll drop one that's 0.3 or 0.4.

I used to use the Dillon 550 measure and it helped to know when to expect powder charges to be heavy (i.e. if you banged the press).

Every powder measure's accuracy is dependant on how smoothly and consistantly you operate it. I've found with many measures, if you tap the body before you drop each charge, it helps.

+/- 0.3grs should deliver superb accuracy out to 300yds with a decent load.

I have a Lee measure and it does fairly well. One of the things about it IMHO is that you have to be consistent in how you use it. Also if you get into the habit of giving it a tap during setup and then tap while you're using it between throws it seems to help. I'm metering out H322 and have no problems...

I must admit though, I set it to throw short and then trickle up the last 1/10th grain on my digital scale. It really doesn't take me that long and I shoot a bolt gun so I don't really go thru all that much ammo.

PS - Pick up a digital scale if you don't have one. I have an RCBS Rangemaster 500 I think it is, great little scale for the money. Trying to weigh every throw on a balance scale would make me want to give up entirely.

Thats exactly what i ended up doing. After you get into a rhythm it starts to go pretty fast. And yeah, having to weigh every load on a balance was driving me crazy.

I loaded up 50 rds with 42 grns Varget and used Privi 168 grn BTHPs, LC 05 brass. My results weren't too spectacular today. In fact i was pretty dissapointed. But then again, i can always blame it on the guy next to me who was covering me in hot brass from his Mini;)

Tell the guy shooting the Mini to lay a rag over his scope when he shoots. You won't have to worry about getting hit and he won't have to look for his brass. My Lee power measure is + or - .2gr i can live with that. Really that's not to bad for a 20.00 measure. Mike

Yeeesh yeah buy yourself a digi scale, so much easier to do the whole trickle deal with. Also works great for sorting projo's and brass...you want to see anal?

But once you have the cases you're set...so the effort is IMHO worth it. Ohh the scale I use is to the right in the first pic...works great IMHO and is battery powered or AC powered which is convenient.

I was going to start weighing brass for highpower, but I just wussed out and bought Lapua for the 600 yard line (and use LC -- sorted by year only -- for the short line aka 200 and 300 yard lines).

Harrells Precision makes the best powder measure I've ever used, and I've used almost everything. A Million Benchrest Shooters can't be wrong:D

It's definitely worth the cost.

Yeeep that's a lot of coin for a powder measure. I think I'll stick to throwin within a 1/10 with my cheeeepeee Lee and trickle up on the digital scale.

It's not so bad really...just kinda vege in front of the TV while you do it. You can't go wrong with Lapua brass, the stuff is great...but you pay dearly for it :-)

If I were paying that much for brass I'd start thinking about annealing the case necks. Currently I neck size only, that helps extend your brass, but eventually the neck will work harden and crack.

I weighed some LC brass last year and culled out everything that was more than one grain off the average. This group was shot with the rejects (and I didn't weigh the individual charges).
