RE: 250gr TMZs Versus 290 gr TMZs
I've yet to shoot the Barnes Spit FireTipped MZ sabot so your post is of great interest. I have shot the Barnes Spit Fire Boat tail in 285 and they are just a fantastic shooting projectile. Out of my Knight Disc, I truly feel I could, "with more practice" shoot out to 200 yards with little problem. My big complaint with the Barnes line of bullets is their cost. I just hate to go to a range session and spend $20.00 on the projectiles. Call me cheap, frugal, tight, I don't care. It's the same reason I refuse to shoot powerbelts.
My idea with the Barnes is find you load, record your load, and then hunt with that projectile. I think that tipped Barnes would really work well on large game. What is your opinion of their penetration ability? If they are like the other Barnes line of projectiles, they will sink in deep and hold together..
