One of many powders thas has been sold under the name «5744» through the years, this powder is presented as being particularily suited for reduced rifle loads. In a thread, somewhere, I made som critical remarks based on my experience with this powder. Mediocre accuracy, unburnt kernels.
Well. I kind of reviewed my own tests, and found that I had not been systematic at all. Completely insufficient data to conclude anything at all, really. So I’ve decided to take a new look on this powder.
First, I tried a variety of loads in my S&L 30-06 with the XCB- bullet, and regular lube. At 26 grs I shot two 5-shot groups @100m. 31 and 32mm c-c (no photo). In my world, that is really good. This load was a few grains more than my previously tested loads.
Yesterday, I shot my Rössler 30-06, with the excellent (!) Arsenal molds 170grs HVTH1- bullet. Regular lube, home-made GC, Norma range pick-ups at their 15th cycle (without annealing...). I had loaded for 2 5-shot groups with 26grs D060, but the first five were used to walk into the target.
For comparison, 3 5-shot groups with my standard always-works 19grs Vihta N110, average c-c 33mm (last photo).
My (single) 5-shot group with D060 was 24mm c-c, which is 0,8MOA @100m.
I’ll shoot this load some more, of course. And update this thread as I gain more experience.
Had a nice range trip yesterday, alone on the range with 4 rifles and ample supplies of coffee. The Rössler is the bolt gun with the piece of garden-hose as thread protector
