It can vary with powder lots as well as barrels. Some barrels are simply faster than others, and they speed up for a hundred rounds, sometimes more. For 103’s I’ve seen it run from 29.7 to 30.2 grains of H4895 for the low node. This particular test it was 30.0 grains and all barrels were 28”.
Thanks - That lines up with what I am seeing with Berger 105's. I get really tight at 2890 with that bullet. sounds like the place to be.
well i guess not.. sorry for askin
I've thought about but got no farther than that. Weird thing about 6.5 Stabal though i had a 7-08 improved barrel on the Panda and tested it pretty thoroughly one fall after the match season was done. It tuned up well and gave very good accuracy but the problem was something about the powder kept the Sharpie paint on the bullets from transferring to the target paper at 600 yards, even dripping alcohol on the holes to get the color to bleed off them was pretty tough to do.
yeah.. just the Stabal that is good for 223 i think might work.. another powder i have thought about is 2000MR
it seems that there isn't any interest in this thread anymore.. i wish i could help you.. but like you, just a duck stuck in a puddle
It seems powders in that burn range run out of case room before they get up to BRA speeds. That shouldn't be the case with the Stabal.
I've heard it discussed before and most said the temp insensitivity is not as good as the H version. I haven't heard of anyone actually testing it.
I haven’t tested it personally so grain of salt this but a fellow shooter at the range is using imr 4895 and was having some nice looking groups. Said it ran a little slower than h4895. Give it a whirl and let us know how it works out for you.
GRT shows that too.. for it to be a lil slower then the H version
Never pushed it faster because it grouped so good here.
Below is an example of what I'm referring to. This was shot at 550yds and 31.5gr of Varget with the 108s was very competitive in this barrel. Dots are 1.5"
