Time for a comparison with SMKs. I have a good feel for the behavior of the Hybrid in various densities of media, as I do the SMK. The only remaining thing to do is/was to shoot the Hybrid into the backstop full tilt, as I have done with many 300 SMKs. Generally SMK penetration is about 8" of blow sand (very fine) which is supported between plywood which is mounted on the 8" side of railroad ties. The SMKs open a wound channel in the sand such that usually the 2nd shot and always the third shot complete penetration, Those that penetrate are usually found laying on sand immediately behind the backstop. As in, they barely penetrate but fall to the ground within an inch or so of the base. I am sufficiently comfortable with consistency of fabrication of the Hybrids to rely on very few shots to get a performance sample. In this case, I selected a single representative bullet from the 3 remaining for this test. The SMKs have been shot at 200 yds. Note the penetration numbers above. The Hybrid was shot a @ 300 yds. The weight of the sand and weakening of the front piece of plywood (lots of holes) has caused a bulge such that the width of the sand is a little over 12". Muzzle velocity was the same for all shots except that H-1000 was used for the Hybrid and US-869 for the SMKs. (Running low on 869, use it in the 270 AM, plus H-1000 gives lower ES) For an unbiased observation here are 4 SMKs and one Hybrid. Which one is the Berger 300 gr Hybrid? Yep! #4 from the left. Side View Remaining weights: SMKs 94.2 to 106.7 Hybrid 97.0 Penetration: SMKs average of 8" Berger 11.5" Note: No first SMK has penetrated to the depth of this single Berger that was called upon to represent all of the 300 Hybrids. Its a real hero. Note: It has been a couple of weeks and plenty of rain to pack the sand and keep it wet. More SMKs Conclusions: You make 'em.
