What do you think of BH209?
"If your gun doesn't light blackhorn 209, get one that does"--we say.
It is harder to light than other substitutes, but it is worth having a gun that does. It's the single biggest advancement in muzzleloading. Yes, I know that includes the inline from flinklock, the sabot, the 209, etc. My opinion, this is my favorite of the list.
Any inline will ignite 209 so long as the primer ignition channel is a sufficiently large enough diameter....
Here's my experience with it regarding weight by volume and accuracy nodes. My Thompson Center measurer, the clear one with the funnel shaped top, throws about +- 2 grains. I have found that to be an intolerable amount, here's why:
I decided to treat my TC omega like a "real rifle" regarding accuracy. I decided this would be a worthwhile venture, as we have seen with shotgun(sabot) slugs, it might matter big time if your gun likes that slug, so the test was on.
I weighed charges from about 98-102 in .7gr increments. Yes, .7 gr increments. The weights are in the high 60's low 70's, which checking my notes was 7 or 300 magnum type numbers. Using that info, I hoped .7 gr would be the right amount. The five groups were fired in round robin fashion until all 5 targets, and therefor load, had a 3 shot group showing. The results were shocking. Same shooter, same gun, same powder, same bullet, same day. Only change was a powder charge from roughly 98-102 gr by volume. The best was a perfect clover leaf, the worst was a 4 inch horizontal spread(scatter node). Just like a "real rifle", arguably more pronounced.
Other details, TC omega, BH209, Hornady SST-ML hi speed lo drag, range 100yds.
The results were enough to warrant more testing to find a larger wider accuracy node. Cool, eh
