Today I was shooting my 30 BR. I had just had this rifle restocked and this was its first trip to the range. I was shooting my standared 30BR load with a Micheal Taylor 118 Grain 9 ogive bullet and 34 grains of H4198 ahead of a BR 450 primer. I had shot 50 bullets and was loading up everything when I noticed that on the left side of the rest was a lot of unburn't powder, by a lot I mean at least 25 or 30 grains or so.
At first I couldn't quite figure how the powder got to were it was. I had a friend spotting for me, I shoot left handed so he was on the scope to my left on the other side of the rifle. He had his cell phone laying on the bench and after each shot there would be a "FEW" grains of this unburnt powder on his phone. The phone was about even with the back of the rifle. I would think that any unburnt powder would get expelled down range, but his phone setting 28" or so behind the muzzle and over by that distance still had powder on it after each shot. The rifle a Farley actioned rifle does have a compensator installed so maybe some of the powder was being expelled side and to the rear some.
I looked at the bench and there was quite a bit of powder inbedded in the carpet, that is where the 25 or 30 grains came from. I looked at the powder and while my load of 34 grains of H4198 is close to a Compressed load in a 30 BR case the expelled powder did have a different look to it. It is an extruded powder like H4198 but appears to be larger and there is a "HOLE" down the center of each grain.
I am stumped. I am pretty sure that this powder did not come from my rifle as it is just not H4198 I don't believe. But what powder could it be? Maybe it was spilt powder from the previous shooter and the vibrations made it jump to the cell phone ----HUH?? But maybe.
Anyone familiar with this extruded powder with a Tunnel down its center??
