Update on 8208 powder
Posted: Mon Apr 12, 2010 4:02 pm
Nice day for testing at the range, mid 60's w/5-10 quartering wind. That's good for Wyoming.
I went with Broncs & Whiskey to the very nice Douglas facility.
I have been getting good groups with 27 grains of 8208 and 39 SBK's but didn't have velocity results, so I was reluctant to call it a good load.
Today I had 27 grains loaded behind 40 vmax, 40 berger, 39 sierra--no moly. The Berger's and SBK's shot very well in my Ugly Stick(Browning a-bolt, gray laminated stock, Shilen stainless in the raw) with nice 1/2 inch groups of 5 shots. Vmax's were under 1/2 from my Savage VLP. The Shilen is 1:10 twist 25 inches long. Velocity from low 3700's to low 3800's. The Sierra's were the slowest, Berger's fastest, and the Hornady's right in the middle. Pact chronograph pooped out on us before the Savage velocity could be checked in the 1:12 26 inch factory barrel. I expect it would have measured a slightly higher velocity.
I've never gotten good groups with the 40 vmax before. The loads shot to the same point of aim in the Savage and also to the same zero as my pet load (39 sbk-moly, 24.8 R10X often in the .3's). 40 vmax load was an inch left of the other loads in the Ugly Stick, same elevation. I just switched scopes on it so I didn't compare to the old zero. This rifle also likes the pet load, but like many $2,000 vasrmint rigs it's just not as accurate as a Savage.
I'm ready to declare this powder a good one. All my 204's will be loaded with it next season. Moly coated 39 sbk's will be the bullet of choice-no reason to change that.
By the way clean up was a breeze.
Shane put together a Savage made up of parts laying around(swap meet factory barrel and action from a sporter weight used bargain rifle)put them in a Medalist stock and he outshot me, as usual, first time out. He used 39 sbk's with 25.5 grains of Benchmark to do that dirty deed to his father-in-law. I didn't offer to let him shoot the test loads, probably would have shot 1/4 inch group.
