I had 3 boxes of 220gr. Remington Ammo that performed subpar for my liking. I decided to pull the 220gr. bullet and replace it with a 130gr. Barnes TTSX. I used the same case, primer and up'ed the powder by 2gr. Since I was using a much lighter bullet subsonic was not a goal of mine but a good hog killing bullet.
I was able to purchase some powder and primers at Cabela's two weeks ago and built some bullets from scratch using a heavier powder charge.
It never occurred to me that their was a "minimal fps" for the Barnes TTSX to expand. Research states that you need a minimal of 1600-200 fps for the bullet to expand properly. I am excited about this bullet and hopes that it will deliver some dead hogs and varmints in the future.
