Good news, the 444gr powerbelt flatnose is under an inch! (I said flatpoint in my original post, i meant flatnose, sorry)
Being from the Georgia and huntin these whitetail the 295 powerbelts have always worked great. Being unsure and my first Colorado hunt for Elk I called powerbelt and they recommended either the 338 Platinium or the 444gr and they assured me the 444 flatnose was legal in Colorado. I pressed them which they thought was best and whoever i was talking to said the 444. Once i became aware of the 2X bore rule i did put the micrometer to it measuring "from the base of the nipple that the skirt attaches to, to the flat nose" and get 0.975 (close but legal!).
Then I found out about the Blackhorn 209, drove a 3 hr round trip last week for two containers (all they had in stock) and went to the range last Saturday. They seem to shoot fine, my longest distance shooting so far was 80yd and they grouped fine. Everything advertised about the 209 powder seemed true. No cleaning every 2 or 3 shots. I shot about 8 powerbelts in two barrels each and the 8th reload was as easy as the first. Cleanup was a snap. I used a light weight oil on first cleaning patch and it takes the majority of soot from the barrel. My encores will never see pyrodex or T7 again.
It would be interesting to see chronagraph velocities of the 444gr with the 209 powder. Don at Western Powder gave 1597fps with 100gr Blackhorn 209 behind the 444gr flatnose powerbelt and a 26in barrel.
We are hunting south in the conejos area and San Juan National Forest.
