Title: which powder ?
Post by: hnusz on April 08 2015 11:30:04 AM MDT
Which powder would be the best to use for mid to upper power range. I have unique auto comp 800x Aa #2 7 5. Will be using 165 gr. jacketed flat point from xtreme. Lee turret press with a rcbs uniflow powder measure. I have a dw rz 10. Thanks

800X is good, but meters terrible.  AA#7 can deliver some good numbers too.

Seems like I have read that auto-comp is a good powder for 10mm, but I am not familiar with it personally.

Of your choices I would look at #5 or #7.

A7. You could easily get in the 1300s, and it meters so reliably that it can safely be metered through the Uniflow, as long as you're at least a skosh under max. I see deviations with A7 from my Uniflows of about 5/100 grain. It is also clean and low flash.

800-X would be the second choice, but it comes with some hassles. Drop and trickle that powder please.

Which powder unfortunately at this time might have to be settled by who has any in stock.

Thank you Obozo!

800x is fine to use without weighing/trickling every round, but you have to test your powder measure.  With my Lee autodisk, I set it at 8.6 grains, got some wide variances, but I'd be comfortable mid-range with it.  Statistically, there is a 1 in 10,000 chance of throwing a charge 0.4 grains or higher than average.  That 1-10000 chance is what I set as an acceptable level of risk, and the 0.4 grain was calculated with weighing 200-300 throws, both with constant powder level (throwing the powder back after weighing) and with diminishing powder level.

My other Lee powder measure (Perfect Powder Meadure) cannot be trusted with 800x.  Powder throws do not fit on a Bell Curve, and consistenly throw 1 grain above/below average.

I agree... I use Four different measurers...

The Lyman dosent do well with 800x or flakes in general. The Uniflo works perfectly as does the RCBS rotor powder drop. The Redding 3BR is also no problems.

Dryer sheets and regular old soap and water washes (where applicable) remove all static electricity.

I suspect it may be the personality of the individual measures as well, and their design.  When changing powder measures, throw a hundred and see what the variance is.  If that seems like a lot of work, do it while working up a load that you will be weighing each charge anyways.

got to the range before the rain the 10 shot great not much recoil brass looked fine going to bump it up loaded the .40 and the .45 with 800x I use a lee beam scale and a small hornady digital scale to check weights check with digital first easier to read then I put it on the beam for final check throw 10 measures in a cup weigh the 11th if no change I will start loading I check every 15th round the 800x was consistent loading the .40 and.45 going to load some for the 10

I find like in most things Consistency is tantamount to good shooting...or in this case reliably consistent powder charges.

I use a baffle, I keep the hopper at least 1/2 full and a tap the measure at the bottom of the stroke 3-4 times as if you needed to help powder trickle out.  When I do not do this, I fined FAR less consistency.

I don't have that problem. My Hornady Auto dispenser works with any powder.

I've gotten good results using AutoComp, it meters well and gives worthwhile performance.  I've used AA5 before but it's more lower/mid end although it's good powder.  AA7 would probably work well too.

Love 800x but for me it's for upper end stuff only.

Haven't use dippers since I was a teen with my dad... Even with the Lee loaders that worked via hammers

But I do remember they were pretty consistent if you tapped them after filling to let excess off...in a mid range load , no problem esp since you pick a scoop that was under the load wanted

I still have the full set of Lee Dippers, but hardly ever use them anymore. But they will be there when the Zombie Apocalypse occurs and there is no more electricity or batteries left! ;)

Exactly why I like the balance beam scale, real printed load data and notes.  Should the SHTF, I can still cast over an open flame if need be, and maintain some various supplies for sustaining my needs!

They are continually talking about and EMP event or solar burst that will take down the electrical grid system... :o
Title: Re: which powder ?
Post by: gandog56 on April 28 2015 08:52:37 AM MDT
Yeah, but when you are living in that cold drafty uneven floored cave, dippers would be better!  ;)
Title: Re: which powder ?
Post by: sqlbullet on April 28 2015 09:15:33 AM MDT
I will take the balance beam any day over dippers.  Especially in an EOTWAWKI scenario.  There is mass that is relevant in reloading than the powder.

I remember those first bullets.... And the overwhelming feeling that hitting a loaded she'll with a hammer was not the best idea...

I also have the dippers... Mine are black plastic! They can be useful for plinker loads for sure. Always need a good BB scale tho!!!

Yes the beam scale has the final say in the weight. Is the Lee good enough or should I get something better.  I'm going to start loading rifle shortly.

the Lee balance scale is accurate ( after leveled ) but the 1/10 area of reading scale is a bit of a pain... I'd look for something with like a wire weight for the 1/10ths.

The scale is the one thing that keeps our fingers and eyeballs intact. So scales are a good place place not go for a "price point" model. An RCBS 5-0-5 or Dillon beam scale are both great scales. Very similar since both are made by Ohaus. Back those up with some check weights and off you go for a lifetime. I have also found a powder trickler to be a boon to drop and trickle rifle charges. Of course, if you are flush with cash, the RCBS Chargemaster would be awesome for rifle.

Keep in mind the Lee selling point is to load for economy and accuracy, not max velocity.  With that in mind all the Lee equipment is great stuff.

But, when I am pushing limits, my RCBS balance scale comes out.
Title: Re: which powder ?
Post by: The_Shadow on April 29 2015 08:07:16 AM MDT
Yes I have used the RCBS 5-10 balance beam since 1978 ;D, and had never really had any check weights to test it.  However I bought a FrankFord Arsenal digital, that you see in the pull-downs, it came with check weights, so I used them to test the RCBS and it was on the money perfect after all these years.  The other thing is the two scales agree with each other...

But with time the digital scale does drift and needs to be re zeroed often, so I learned to deal with its limitations when working with it.  ::)

Post by: Taterhead on April 29 2015 09:17:52 AM MDT
One important, but infrequently discussed, thing is where you put the scale. If the scale is on the same surface that the press is mounted to, the impulses from press operation can move the zero. Scales are ideally placed on a surface that is isolated from the press.

nemloc, welcome to the forum! 
BL-C 2 is a slower small rifle powder and not suitable for the 10mm as such.  Haven't even seen where anyone tried it either. Sorry... ???

Nah, but I am going to try it for 7.62X54R, 8X56R, .308 Win, 30.06, 7.7 Jap, 7.5 Swiss, 6.5 Swede. For 10 mm I have Red Dot , Blue Dot, HP-38, 800X, Unique if I had to.
