Alliant 15.5

[Retired shooter]

Hello all

From those of you that have used it. Your suggestions & thoughts on RE 15.5 powder. . Any comparison to Leverevolution, or CFE 223, or BL -C2. What is the availability factor ? Will be used for 6ARC under 110 A tips..

Winter sucks, got the snow plowed, thinking warmer thoughts, .

Thank you.

To all a good day.

seems a decent bit slower than the powders you’ve listed. It’s also bulky, I’m using a 10 in drop tube to get enough in the case to hit velocity I get easily with N150 in 308. It’s a stable powder and it shoots very good in 308.

You might look at ARComp as it may be a little better for 6ARC. Both are very temp stable.

Availability is a little sketchy as with a lot of the Alliant powders.

I have not run numbers through Q/L . Thought about this yesterday whilst plowing snow.
Freezing my . off.

To all a good day.

I see it most everywhere locally.

Tried it in my Dasher worked pretty good low ES SDs

Several places have it in stock.

I also use it in a Dasher with 109s. It is bulky so I also use a drop tube. Its shoots well and has amazing velocity.

Will run some numbers through Q/L. See what it says. Snow on the ground, extra cold outside. Will be a good time to explore the options.

I use it in my 6BRA when H4895 is difficult to find. Works great. Very low ES and SD. Highly recommend.

Are you seeing the same velocities as H4895?

Are you seeing the same velocities as H4895?

If I remember correctly, I need a slightly larger charge of 15.5 to match my H4895 velocity with a lighter charge. I will check my notes when I get home next week. However, I did not experience any pressure signs when achieving the same velocity. For reference, I shoot 108 and 109 grain bullets in my BRA around 2880-2900.

It shoots really well in my 22BRA with 88eld's. Slightly faster than H4350, about 1.5gr difference for same velocity.
