Volume / Weight for BH209

[SHulion]

What is everyone using for their volume to weight ratio with BH209. I have heard .667, .7, .71 as a multiplier ofvolume. What are you guys using. My Bh209 came in yesterday and I want to weighsome loads for testing.

If you want to weigh charges, make your own standard. Set your powder measure at what you think you want to shoot and weigh five loads at least. Then take the average of those weights and produce all your consecutive loads at that weight, out of that jug. Change jugs, do it all over again. If I weigh charges (which I have been known to do) I never take the weight of someone else. I want my powder measure's average, not theirs....

Thanks for the input. I'll give that a try tonight.. I was just wondering what everyone else was getting.

Lee,

Thank you for you interest and kind words about Blackhorn 209.

You can use 0.7 as a multiplier i.e. 100 volume units x .7 = 70 grains by weight.

We will work on something for side locks, but can't make any promises.

I think MM came up with the following average conversion

Blackhorn 209 VOLUME to WEIGHT calculator:

VOLUME in GRAINS BH209 / 1.5 = WEIGHT in GRAINS BH209

OR... VOLUME in GRAINS BH209 X 0.667 = WEIGHT in GRAINS BH209

Lemoyne's .7 is surely close enough.

Thanks again guys. I am going to weigh some loads tonight 110 gr. volume or 77 gr. weight. I hope to get a chance to do some shooting this weekend. I'll be shooting an Omega with a 250 gr. SW with the Harvester short black sabot and Winchester 209 primers. I hope my results are as good as some of the others I have seen.I also have some 200 gr. SW's. How are ths sabots (blue)that come with the bullets? Do they fit tight enough to use with BH209.What do you think?

[Lefse]

I shoot the 200 gr sw with the supplied sabot in my Encore Endeavor with 100 gr of BH209. They shoot great. They load pretty easy. Even the tc super glide shoot good with BH. They load really easy. I shot one Nosler expander. Didn't think I was going to get it down the barrel.

[Lefse]

I don't think weighing the charge is neccesary. I just use a tc u-view measure. Every group with the load I use is under minute of angle from 50 to 200 yards. Don't need anything better than that.

SHulion,
I can use the one they come with and get under an inch with them. it is very difficult for me to be sure the bullet is seated in the sabot right; the new Harvestoer Crush Rib blue 50/40 sabot is much easier to use and shoots just as good. Lee
