To all, The Haley .58 is a Beast. Jack made me a great .58 Boomer Carbine, I shot it last weekend for the first time. Reba sent me some 286 Grain Lead Balls & some 433 Grain HP Conical with my rifle. The .58 Caliber 433 Grain is a huge projectile and a .45 Caliber Lead Ball will just about fit in the Hollow Point itself. The Rifle shoots great. I wish I had a Chrony to measure FPS , FT- LBS. But I can say at 35 yards the 286 Grain Round Ball goes half way into a pine 4"x4"( 2-2"x4"). The 433 Grain HP also does heavy damage to the 4"x4" post with full penetration. Hunting@ 50 Yards or under should be no problem. Seth gives a great description / Information on the .58 Haley. Jetman / Gary / Disabled US Army
I have yet to shoot a boolit that is shorter than it is wide....closest I've come is the EPP/UG's. Melloroadman send me some TINY .45 slugs that are only .3945 high that I am eager to get out and test.....been tough to get away lately. For target/small game use, I would rather use a HP than a HB if I were trying to lighten a slug of any given length just because I haven't seen as much luck with HB slugs in airguns as I have with the HP's.
I have shoot thousands of bullets that are shorter than they are wide . As long as the nose length is kept to minimine to maintain balance there is no problem . Marvin
