AR-Comp or 8208XBR in a Dasher

[kyreloader]

I have 8 lb containers of both AR-Comp and IMR8208XBR lying around the garage that I purchased for other rifles/project. I have a dasher barrel coming and was wondering if anyone has tried/shot either of those powders with the 105/108 class bullets?

If so, how much and how did your results compare to H4895/RL15/Varget in regards to velocity/precision?

I may just use it for fire forming, so any ballpark charge amounts will be helpful.

Thanks.

I used 30.0gr of IMR8208XBR for my 6-Dasher brass fire forming/barrel break in & Speer Hot-Cor Bullets 90 Grain Spitzer Soft Point pills.
Good starter for my setup.

Here's pic of brass 1st firing (post clean)
Will anneal & re-size before 2nd run.
