I only had about 1/8 pound of lot # 4736. With this limited amount, I decided the first thing in order was to see if I can get any velocity out of it. The test gun specs are: 30-30 case, Russian primer, Bartlein 23" barrel, 118gr. 9 ogive Cheek bullets seated .010" into lands. Maximum charge weight is around 42gr based on case capacity. Velocities are for a 3 shot average.

41.0 gr - 3049 fps
42.0 gr - 3106 fps

So far this test only proves that this powder will work in the 30-30, but only low to mid nodes can be used. The truley upper nodes in the 30-30 are over 3200 fps. The 30x47 would make better use of this slower burn rate. One the other end of the scale, I see no practical use for this powder in the 30BR in short range BR. I just can't see it making decent velocity.

If I have enough powder left to shoot 3 or 4 groups, I will post the results later. All you HBR shooters out there should consider testing this powder since your case capacity is even better suited for this burn rate.

Mike,

Got your message the other day. Been real hectic around here lately. Are you headed to G.J.? There are some fellas itchin' to get revenge on that 30-30!:mad::D;)

I try to call you again before to long. As far as fellas gettin revenge, they'll just have to wait for that early Oct. match in G.J.

Honestly I hope to shoot way better next time. I had way to many 4 in 1's. I'm surprised that I shot any groups in the ones in that mess.

I have been using 8208 XBR in 30X47 Lapua for a while with quite good
results. Using a little over 43.5 grains and 118 gr. bullet.
