    New 8208 pull down target results.

    This target is from a practice session fired 2/12/11 at Ben Avery rifle range Phoenix AZ, shot with my new rail, Krieger 13.5 twist barrel smithed by me. Velocities were exceptional 54 on my Bruno powder measurer equaled 3444 average which weighed 29.4 grain. I also shot a hotter load of which did not group very well, however the velocity kept climbing to the mid 3500 fps. Dan Sutton was kind enough to set up his Ohler 35 for me and I thank him for that. Standard deviation was 7 very good I thought. The Group height was consistent all shots went with conditions barrel length was 26.5". Over all 19 groups averaged a very respectable .1789 which for the conditions in Phoenix was excellent also 3 groups in the zeros were the highlight. Most groups were shot with my double-o bullet except the last 4 with my new bullet I call the UNO. The die was made by George Ulrich and designed by me. This is a very good powder, of which I will be keeping a bunch for myself.

    I just tested some of this same Lot (122910) of 8208. Up until now, I had only tested the new XBR version. This was a chronograph only session with the full length 30-30, 118gr bullets, and a 23" barrel. I started out by shooting a test load of 40gr of Iraeli 2015 to establish a baseline. This testing has proven that this powder is the perfect burn rate for the 30-30 with medium hot loads. Any 30 caliber case with capacities of the typical hunter class round (30X44 - 30X47) would be very well suited to this powder.

    Test load:
    40.0gr 2015 - 3123 fps

    8208 (122910) loads:
    39.0gr - 2885 & 2891 fps
    41.0gr - 2982 & 2991 fps
    42.0gr - 3062 & 3066 fps
    43.0gr - 3131 fps - very close to all I could get in case - sun went down and gave error, so just one good reading

    42.5gr - New 8208XBR - 3105 fps - chronograped on a different day

    Hunter class shooters should try some.
