Dave Manson has the wildcat bug. He has developed

He smoked a Sika at HHC. I think he said 350 gr. .510" at 2350 fps? He used a modded Rem Model 7.

With straight walls and that huge surface area of the bullet base to spread out the psi it is surprising what it can do. Manson had this chute compact Model 7 rifle with a HS Precision one off stock. When he walked into the room it looked like he was carrying a varmint HB rifle. But no, it had a BIG hole in the tube!

The bullets are the "modern" style that are designed to fragment with a "base" that fully penetrates. The little plastic tips truly add to the aerodynamics in an astonishing manner AND make them feed slick as a whistle. The brand is Cutting Edge Bullets. They would work fine in a .510 GNR too. A huge 350 gr. HP! They are not cheap, but serious specific sue projectiles. In TN the performance was really impressive.
