80 gr fb 1-8 t BRAI ?

[Link]

I have some 80 gr fb I want to try in my 1-8 t. I have Varget, 4198 and h 4895.
If you have tried this can you tell me the sweet spot? I would like to start at the low node and work up , as usual.

OK How about a educated guess? Maybe 3250 fps?
I also have RL 15

I hadn't used any of the powders you listed but I have shot close to 4000 80 gr flat base bullets from the 6BRA in the last 10 months.

2 barrels shot 8208 above 3300 fps really well..by my scales and labradar 8208 with 80s in a 24 inch bbl works out so the charge matches the speed..31.5 grs is 3150 fps and 32.5 is 3250 and 33.5 is 3350..I would start at 31.5 and work up.

My current bbl is shooting well with vvn 135 and H322, I shot 135 last weekend but if I can get up in the morning I plan to shoot 322 tomorrow.
