Sierra HPBT 107gr
so with the D4350 being slow for the 6.5, what would it be a decent option for?
Tried out the D4064 tonight with my .223, 90 grain JLK. First time shooting at night. Discovered my red targets are hard to see at 100m. Lol! Still shot ok though. I only had two groups of 5 for this powder. Similar groups. I know it’ll do better when I can actually see the target.
The D4895 has been excellent in .223, but it seems I should be trying it in .308 as well. I will certainly be picking more up once it's available again.

Thanks. No chrono last night, and the Easter Bunny only brought me chocolate. No Labradar.
Estimated velocity is about 2520 fps based on readings in that range previously, but I question that number. When I test, I just use a basic IR chrono, and if the bullet isn't exactly parallel, it'll read lower. Plus, to avoid issues, I put it about 18 feet away, so all numbers will be lower than at the muzzle by a bit more.
for those curious about D8208 BR I'll post some numbers.
all points are single data points taken from a Satterlee development using magneto speed.
keep in mind these numbers are for my rifle w/ 22" barrel. all brass prepped the same, same head stamp, weight sorted, light crimp applied.

pressure starting on top end of D8208 and slightest bit on IMR noted by primer cratering. I get a lot more primer cratering from factory ammo in this rifle than these loads.
