That'd be a screamer of a deer whacker! Man..

Mike, speaking of 284's, how is yours coming along?
 
And the case design is worthy enough that several wild-cat rounds have been based on it.
 
That is going to be a deer wacker for sure.

Well, this is what I ended up with, but I think it is a little over loaded.

TIKKA T3 Bolt
Fed Match Primer
58.0 grains RL17
120 Grain BT
Velocity 3277
Shoots holes in holes @ 100 yards and 1" group from Model 100 Winchester.
No signs of pressure or primer flattening.

Has anyone else tried this load?

Thanks
