250gr Shockwave & 110ffg T7 FPS??

[MK85Shooter]

I've been getting pretty good accuracy results (ave 1.25" @ 100 yds) with the following combination out of my MK85 with the Extreme 209 conversion kit:

250gr Bonded Shockwave w/supplied sabot
110gr ffg 777
Win 209

I don't own a chronograph. Can someone please give me an estimate on what velocity I'm getting out of this load? The MK85 has a 24" barrel. I'm guessing I'm a little over 1900 fps.

Thanks,

Chris

I would say you are about right. 28" barrels are getting about 2100 +/- with 110 grains, so that would but you about 2000 would be my guess in a 24" barrel.
