Switching from T7 to BH 209

[js4fn]

Thinking of switching from Triple7 to Blackhorn 209

Gun
Tradition ultralight pursuit have two both have diff threads on breech plug

Primers been using
Federal premium 209s

And cheddite 209 primers

Have quick load tubes

What exactly do I need other than a bottle of BH209

[Fox]

About $80

About $80

Go on there Web site and download the load data they have it for volume and by weight when I use backhorn in my 50 cal I choose to use volume and I have the tube that measure it from blackhorn

You will also need to change your primers. I us shot gun primers.

I haven't used BH209 myself yet, but have it sitting on the shelf to be opened this fall . Been around guys using it for a few years now and have read the following.

"100 grains T7 = 1944 fps, 100 grains BH209 = 1968 fps, making BH209 a hair over 1% faster"

Not a + or - that will affect any accuracy in the distances ML are traditionally shot ( -200 yds)

"Blackhorn is a fairly bulky powder so it lasts longer than 777 on a volume basis."

edit add....this would have to be proved out... are there more 100 gr loads (by volome) in 10oz of BH209 than there are in 16 oz of T7.

So when you start to work up a load you can go slightly more 'volume' measurement to get started...ie: 85 gr BH209 should be close to 80 gr T7...by weight.

"Triple seven at max charge makes more pressure than blackhorn at max charge".
"Its about burn rate triple seven is much quicker so higher peak pressure".

...Max loads for BH209 are LESS pressure than MAX loads of T7 ...I think I read by about 15%.

"You do not want to use water or water-based soapy solution to clean out what little Blackhorn 209 fouling that's left in the bore. It tends to turn the fouling to a sticky surface in the bore. Instead, to clean away this fouling, it takes just one or two patches dampened with a modern bore solvent, such as good ol' Hoppe's No. 9. (Western Powders has also developed one of its "Montana Extreme" cleaning solvents expressly for Blackhorn 209.)"

Unlike T7 apparently BH209 doesn't like water....so you'll have to change up how you clean up..I've seen guys using Hoppe's 9 and it cleans well.

Good luck, let us know how you like it...

Thought my primers would be good to go






Switched to federals because they were suppose to be cleaner didn’t see much difference

[fishhawk]

I made the switch to blackhorn 209 years ago, will never go back to 777. BH is much cleaner burning and cleans up very nicely with regular gun solvents. You must use a hot 209 shotgun primer with it, CCI and Federal are recommended. DO NOT use a 209 primer designed for muzzle loaders.

Cheddite .209 Primers have been around for ages , long before muzzle loaders came out that required shot shell primers.
They were and are designed for shotguns/shotshells.

"Blackhorn is a fairly bulky powder so it lasts longer than 777 on a volume basis."

Have you verified this yet? The 777 comes in a 1lb can, the BH209 is a 10oz can.

[Fox]

Based on the BH209 data it looks like FFg 777 and BH209 run about the same weight to volume conversion, the FFFg 777 is a little more dense, so the cost of the 777 is still about half of the BH209.

If that matters to you.
