There are bunch of threads on long throated Handis, that's the norm for most calibers, but not all, the .45-70s are just the opposite, much to the dismay of those that want to shoot big bullets. I can reach the lands in my .35 Whelen RMEF with 250gr Speer spitzers, COL is 3.50", velocity is 2590fps with BL-C2, 3 shot groups are less than 1" at 100yrds.
