I haven't messed with the concept in 30-30 but I have a box a Speer 235 grain spitzers to try in my .375 Winchester. Will it be worth the trouble and make it flat enough for far enough to justify? I don't know but if I can develop a zero that will let me hold center mass to 200+ yards I'll consider it a success. Hornady just won't make any of the good levergun ammo in this caliber. I understand why, but it's still frustrating!
