Powder Help!!!

[Bowtech7]

Okay so I'm probably over thinking it but got a new CVA accura v2 and it specifically says up to 150 grains of powder by volume....But I've been weighing powder wrong in the past by 100 grains of weight. So my question is is there an conversion chart for triple 7 ffg and pyrodex rs select to figure out how much powder by volume I should use or is equal to 100 grains of weight. I was going to weigh my powder out on a scale to have accurate measurements. Any help is appreciated

I'm a little confused by your question but black powder is supposed to be measured by volume. You do have a powder measure, right? I suppose it doesn't hurt to weigh it after you measure out 100 grains by volume, but it's not necessary.

I think he does not have a measure and has been weighing it.

I reload rifle bullets also and have been weighing a 100 grains of black powder on my rcbs scale as I would if I weighed smokeless powder and just realized today 100 grains of black powder is not 100 grains by volume. I have some plastic pre measure tubes and filled it to the 100 grain by volume line with triple 7 ffg and weighed anywhere from 77 to 84 grains of weight So my question is how much black powder should I use in grains of weight so I can measure it out on my scale. Bobcat I looked at that chart and it didn't have pyrodex select on it only p for pistol.

Why can't you just buy a black powder measure and do it by volume?

[Bowtech7]

I guess I could but I'm not sure what those look like

Look through these.

Or better yet, shoot pellets.

I have the same rifle and found 100 gr of ffg shoots the best for me by far.  Pick up a powder measure and go that route.

[Bowtech7]

Sled that's what I'm going to do now that I have done research. Thanks for the helpful input

Pellets are harder to ignite. More prone to draw moisture. And can't dial a load in as well as loose powder. Sure seems like a step backwards to me. I think the o.p. has the right idea about getting  a powder measure and going from there with loose powder.

[Timberstalker]

Sure.  Notice I recommended a link for the powder measures.

To the OP, best of luck getting this dialed in.

. The 290 gr Barnes ez, and the 300 Lehighs shoot almost identical for that powder charge BTW.

Double check my math, but this should be pretty close or possibly help you out some.

You are getting weights from 77 to 84 grains with a 100 grains by volume. Let’s average that out to 80.5 grains of volume per 100 grains in weight (77 + 84 = 161) (161/2=80.5).

80.5 / 100 = .805 grains of volume to 1 grain of weight.

100/.805 = 124.23 (rounding) grains of weight to equal 100 grains in volume (double check 124.23 * .805 = 100.005)

Definitely double check this, I did the math in 30 seconds in my head.

I personally have not had any consistently shooting pellets out of my CVA. I use Triple 7 powder at 90 grains volume with 245gr powerbelt and I am having a lot more consistency.

Good luck and keep us posted on how/what your results end up!

There you go! A little algebra from there and you will have a pretty close weight to volume idea.
