250 gr Swift A-Frame loads for 338 Lapua needed

[effendude]

I am going on a coastal grizzly hunt this fall and want to use my Sako 995 in 338 Lapua. I picked up a box of 250gr Swift A-Frames and can't find a Swift manual. I found some info on the Vihtavouri site for the bullet and I could cross reference those powders against Hodgdon but if anyone has some experience I'd sure appreciate it.
Thanks,
Scott

From the loaddata.com page, sourced as Swift data, and Swift A-Frame.

81 grains IMR 7828 2729 fps
81.5 grains H-4831 2717 fps
81.5 grains RL-22 2726 fps
88 grains H-1000 2703 fps
90 grains RL-25 2861 fps

Max loads in source, 24" barrel.

Good bullets my partner used the 275 for his grizzly.

I'd go straight to RL26. Run it up to 92 grains in lapua brass with a CCI250. You should see around 3025 fps without any problems.
