I am a long range muzzle loader hunter. I have a .50 cal TC Omega with laminated wood stock that shoots very nicely at long range. I have only shot BH209 through this gun.
This is my elk load:
85.2 gr by weight
300 gr Bonded Shock Wave in a Harvester sabot or a 290 gr Barnes TMZ
Winchester 209 primer
I have a Kahles scope with ballistic reticle and it lines up almost perfect out to 300 yards. The lines are 100, 150, 200, 250, and 300 yards.
This is a 200 yards group:
At 300 yards, the group opens up to 4" but I will take that. The POI is about 3" below the POA but it's well within minute of elk. I will be carrying this combo for my mule deer hunt in October except the bullet will be a non-bonded SST. Deer are not hard to kill and I don't need 2+ feet of penetration.
The 85.2 gr of BH209 is equivalent to 120 gr by volume. I weigh all of my charges now and the flyers have gone.
