Powder volume: Titegroup v. Bullseye v. W231

lrrifleman · Oct 12, 2016

I have a minor dilemma.

After my accident, I wasn't in my work shop for a few (read 6) years, and some things found new places to hide. One such item was the large primer plate for my Dillon 550B. I want to find it before I let the few moths out of my wallet. In the interim, I plan to use my old Hornady Pistol Powder Measure to throw charges for my 45 ACP and the 41.

My dilemma is, considering how ancient the Hornady measure is, none of the bushing charts provide data for Titegroup. For anyone that uses a bushing or volume bar for throwing charges, how does a unit of Titegroup compare to either Bullseye or W231, when set for Bullseye or W231?

I realize that I am asking this awkwardly. I am trying to get an idea of how I can expect the existing bushings to throw a charge of Titegroup. Can anyone provide a little help?

On this page on the Lee site there is a link for a VMD chart that will give you exactly what you are looking for.
Instructions - Lee Precision
Look under powder handling and click on the VMD link.

I know Bullseye takes up very little volume which when used in long cases makes it susceptible to double charges if you are not careful.

If you don't set the volume with a balance beam scale, how do you know the voulume from any bushing is accurate?

I'm fairly sure from what was asked the OP was looking for a starting point that would be verified with a scale so as not to have to go through a bunch of bushing before finding the right one.

I've used both HP38/W231 and Titegroup for my 45ACP and seem to remember that they are both close to the same in density, with Titegroup being a bit denser. Don't have any experience using Bullseye though.

I always confirm the accuracy of powder dispensed by bushings or powder throwers. I could literally test the charges with all 11 bushings, but I was just trying to get an idea of how close the 3 powders are with respect to volume. I know that with Bullseye and WW231, the bushings consistently would be within 0.5 grains of each other. Specifically, a #2 bushing would throw 2.8gr of Bullseye, while throwing 3.3gr of WW231.

Thank you.

The VMD chart that you suggested gave me a good feel for the differences in the powder. Specifically, Bullseye seems more coarse than WW231, and Titegroup is finer than WW231.

I suppose you could cycle it a few times (6-12), weigh a few charges, average them, and then calculate the approximate volume using the VMD chart.

See how easy we have it with modern equipment and non-arbitrary cavity markings?

I've always used lee's powder dipper chart to find the volume of different powders.

Hornady has this chart on their website for a bushing chart for pistols, It has titegroup listed.

I'll buy "check the volume" with a scale but don't understand "set(ting?)" the volume...

If it has to do with a Dillon press adjustment or bushing on the Hornady unit I'm lost.

I, too, use a LEE dipper & chart to initially cross-check VOLUME vs. WEIGHT on any pistol load.

Cheers!

Looking at the chart it seems Longshot is close to Titegroup and the bushing you would use for LS would be a good place to start.

I don't have any charts but I do have dippers , a more archaic method than yours.

.3cc Lee dipper: Bullseye = 2.8 grains
Tightgroup = 4.0 grains

.5cc Lee dipper: Bullseye = 5.0 grains
Tightgroup = 6.4 grains

Home made dipper from 25 acp case: Bullseye = 3.9 grains
Tightgroup = 4.6 grains

Home made dipper from 32 acp case: Bullseye = 6.5 grains
Tightgroup = 7.7 grains

As you can see , Tightgroup will be heavier when compared to the same volume of Bullseye.
All of these weights were verified by myself on a scale.
This will help select a bushing, but only an actual weighing with a scale should be done, I probably didn't need to mention that to you but for the safety police out there, I did.
