dropping powder

I have what may appear to be a foolish question!

I have recently acquired a Panda in 6ppc.

I have a Harrell's powder measure, I just bought an 8" drop tube, was using a shorter tube.

How critical to accuracy is the height of the powder column in the case?

Charges over 28.5 grains are the culprit...

If you drop fast, the case is full, and the bullet difficult to seat, dropping slowly allows the powder to compact lower in the case, seating bullet is easy, no significant force needed.

I am relatively new to v-133 and real new to the 6ppc case.


Thanks in advance!!!

starting points...?

I have an MS Excel spreadsheet with the settings I use for 8 or 10 powders on it. I'll send you a copy if you send me an email and request it.

If you have monitored this Forum for very long, you know that with 133, we use what many would consider a compressed load. When you get anywhere above 29 grns, the case runs out of room pretty quick

The fact is, 133 is actually on the slow side for the 6PPC with typical 66-68 grn match bullets. Many of us, however, have found that if you shoot it at an elevated pressure, it acts much like the old IMR 4831 does in a 30-06. My favorite loads with 180 grn bullets was always 60 grns, which is a compressed load. But man, does it shoot.

133 acts the same way in the 6PPC. Just when you think you will not get it all in there, it really starts to tighten up.

A slow trickle with a 8 inch drop tube is the answer.......jackie
 
Thanks Jackie.

That I believe is the answer I was looking for!!

Thanks again!

yes...operate the measure handle........

..........s--l--o--w-----------most will tell you it also yields the Harrell measure it's best repeatability when this technique is used.
My experience has shown this to be true.
 
While the case is under the 6" drop tube, rotate the case in your fingers so that it spins under the drop tube, drop very slow and the spinning will keep the powder stacking very tight. I have been known to put well over 31 grains VV 133 in a 6mm PPC.
