[QUOTE="comfisherman, post: 900551, member: 8394"] Well, if you trust the BC of the 58g v max as posted on the box. You could shoot at 100 yards, them move farther out and measure the drop at say 300 yards, compared to 100. Then pull up a web based ballistics calculator, and reverse calculate velocity. Handloads.com has one that would probably work for that, might take a little trial and error. I'd hazard 200-250 fps loss in an 18 inch tube. I have cut a 24 to a 18.5 in 243 and lost the low 200s on the light for caliber bullets like the 58. [/QUOTE]
