To all,
Due to the lack of expansion of the 190 SMK in soft tissue from 308 velocities (2657 to be specifec) between 100-600 yards, I have made an effort to modify the bullet's meplat to help it open up a bit. The original bullets from the box are an average of 1.355" long, some being much shorter and some a bit longer. I uniformed the tips and made them all 1.340" long. The nose is square now. Then I opened the tips up (the hollow point) from 0.020" to 0.040". The old meplat diameter was 0.055" and is now 0.060" wide. My questions to you who have experimented are these:
1: How much better can I reasonably expect they will open up and expand when hitting the rib cage of a deer size critter?
2: What percent of my BC can I expect to sacrifice (loose?)
3: I cant remember the 3rd question so I will ask later.
Thanks for your advice.
