I've been wanting to try some, but Powder inc will only sell it in 25#lots.
Crater fireworks,blasting and black powder in Mineral IL. had some so made a trip over there and picked up a couple of pounds of 2F Diamondback $ 9.50# and some other powders.
Did a little comparison of density of volume between powders all 2F. used a CVA powder measure set 50 grs. and taped 3 times to settle the powder and scraped off leveled 3 times for each powder then averaged the weight.
Swiss 2f 54.9
Diamondback 52.5
Goex 49.5
Schuetzen 51.4
KIK 50.5
NEXT I put all the powders on white sheet of paper in little piles the color is kind of shiny like Swiss, but more course, more on par with the other 2f's. I don't have any screens to go any farther with this.
Next loaded some loads up with Swiss, Diamondback and Schuetzen in 40-65 in a Ron Long chamber in Shiloh Sharps 32"barrel
Rem cases reformed from 45-70 paper over flash hole CCI Br2 primer 58 grs. BY weight Swiss 2F on this lot#, .030 veggie card, .150 compression, paper on top of card 400 BPS RCBS at 30-1 acc wt 408 GRS. Spg sized .410 The brass is fire formed slip fit the bullets. This my load for that rifle for Swiss 2f
The Swiss, Diamondback and Schuetzen are all loaded the same and same VOLUME of powder, not by weight.
Swiss 2f 1300 fps on fouling shot/ 1256/ 1251/1252/1245/1245=11fps spread
Diamondback 2F 1141 f/s 1089/ 1076/1068/1074 /1063=26 fps
Schuetzen 2f 1129 f/s 1095/1118 /1103/1082/1088=36 fps
String of 6 shots then wet patch then dry on each powder and Swiss was cleanest then diamondback then Schuetzen and fouling softness was about the same on all.
I did not use a blow tube. cleaned the bore before changing powders.
This is just a little test on Diamondback powder to see the energy it has and how clean it burned. The day I did this it was 20 degrees, dry air,wind wasn't bad 10 mph but it felt cold !!! Tried shooting group at 200 YDS but with the heavy clothes on and the cold on my hands, they didn't work to well.
I like what I've seen so far and with some load development this 9.50$ a# might be a great deal . Hope this gives a little in sight on the powder.
