Im 100% sure i said MANY CFs and that includes 45/70 ect and numerous Mag pistol rounds that are required in some states. 50 Alaskan would come to mind but it shoots almost entirely huge slugs at less fps. 50 Beowulf, 458 SOCOM and the 35Rem is probably no better and many 30-30s arent exactly 200 yard tack drivers.
Many is much different than ALL and a Savage will easily match a 450 Marlin too in ballistics. Swinglocks new sabotlesss MLs are using bullets with over .300 BC and doing very well if you want to take it to the next level with his 416 or 6.5 guns
Like i said, it takes some deep pockets if you really want to play but i draw the line at sabotless with smokeless. The PSI is just getting too high for my tastes.
