I have a T/C Impact inline rifle in .50 caliber. It has a twist rate of 1:28. I tried using Buffalo Ball-ets, at 245 grains, will less-than-expected results. I tries some sabots with 250 grain .45 bullets, with similar results.
I put my data into the Greenhill formula, and it calculates that I need a projectile 1.4 inches long to stabilize. Does anyone have suggestions on longer bullets? I see the T/C Maxi Ball at 378 grains, and the Hornady Great Plains bullet at 385 grains. Are there any other good choices? What has worked for others?
