First of all, where did those rules of muzzleloading come from? Is he still alive? He needs his a(!) kicked!!! Just kidding

, had a decent shoot this morning.
Details:
TC Omega, 3x9x40 Bushnell Banner Dusk to Dawn w/ Circle X Reticle set at 7.5X @ 100 ydsand 9X @ 200 yds (range lasered), .451 dia 300 gr Nosler Partition, 110 gr T7 FF, Winchester 209 Primer.
Both targets shot with same combination.
Conditions:
Wind quartering from behind left to right about 10 mph with gusts, mostly sunny with a bit of cloud cover, Temp 45-55' F warming through the shoot.
Target 1:
The first 2 shots are in the green and then they start to rise in order shot as barrel warmed?? or poor shooting[:@]Point of aim was the red circle.
I Chrony'd all five shots. Chrony was 9 paces from the end of the barrel.
1902, 1921, 1921, 1915, 1912 FPS, 5 shot Average - 1914.2 FPS
What rules are you talking about? Please send URL, so we see if we agree with the "rules".
A lot of people have that problem in warmer weather with their barrels warming up, the sabot becomes soft and doesn't do the job as a gas check. One fellow name Harley even made up a Barrel Cooler by inserting a copper rod in the barrel:

I would say that is what the problem is, especially if the first two shots are touching, as they are in your case. I like to shoot from 8:30 am to 10:30 before the day heats up, if you shoot in the heat your going to get results like these. I use the Nosler Partition 300g (the HG Protected Point, notthe 45-70)in my Omega and Knight Disc and have had excellent results with it. Chap Gleason
