Its nearly impossible to get BH209 out here, so i havent tried it. Do you guys know if it will cause rust like the other BP substitutes will?
No sir, it will "NOT"! No rust, no crud ring, minimal smoke cloud. You can load up and set the gun in the gun case and leave it there until next year and bring it out and fire it and it will hit right where you sighted in at. It's not water soilable. Meaning it doesn't draw moisture, nor do you use warm soap and water to clean the rifle like BP substitutes. You use the same cleaners as you would cleaning your centerfire rifle. The breechplug is the hardest thing to cleanup because of the 209 primers. The primers are dirtier than the powder is.
Well I left my gun uncleaned for about 2 weeks after 10 shots of blackhorn 209 and cracked the barrel open today and thought what a mess I'm going to have on my hands! I soaked a cotton shotgun patch in hopps #9, wrapped it around the 50cal jag and pushed it from muzzle to breech and the patch had a giant circle of gobbed powder. I looked down the barrel and not a stich of powder and ran 2 patches down the bore and clean as a whistle. I mainly purchased it for the cleanliness and the accuracy so the velocity is just an extra. No more messy water, soap, cleaners, brushes, etc.
Got to LOVE IT! And it didn't leave any pitting either!
Well, I got that 209 adapter in for my Hawken Hunter Carbine and installed it. I found that a Lee number 3.1 scoop held 32.5 grains by weight, so I doubled that for 65 grains by weight of BH209. Loaded it up with a 385 grain Great Plains and went out back to 40 yards from an empty cat litter bottle and fired, hit it square at the top of the blade. AWEsome! Now, I need to chronograph it and test it on my 100 yard range....maybe when things warm up and dry out a bit. Today ain't the day. I'm excited, though, it actually went bang. It never did that in the inline, just dudded. I gotta admit I was skeptical, but it says in the literature this thing will work with BH209. I'm not real sure how accurate the stuff is gonna be at 100 yards, but if that bottle had been a deer, I'd be eatin' venison.
