I use 245 & 250 grain Barnes Spit-fire MZ & TMZ bullets. I use the 245 grain MZ in my Knight Disc, in front of 130 grains of pyrodex pellets. I use the 250 grain TMZ in my T/C Thumbhole Omega, in front of 130 grains of 777 pellets. I have had fantastic results!

Although the Nosler Partition bullet is a phenominal bullet, and if it flies good for you, don't change, it's a great bullet!!!

Pictured below is my 245 grain Spitfire MZ boat tailed bullet. I had shot a coyote with it and had seen where it had impacted the soil afte passing through the coyote!
