Jeg har bare brukt den flate utgaven av 350 Hornady kula, men jeg har lest bla på Marlin forumet at den runde går greit og, men den er hardere.
Her er et utdrag av et kulekåseri for 45/70: http://www.ballisticstudies.com/Knowledge+Base/.45-70+U.S+Government.html
In the .45-70 the 350 grain bullet weight provides a great balance of high velocity for fast killing, optimum trajectory plus adequate weight and sectional density for use on medium weight game. Hornady offer the 350 grain round nose Interlock and flat point Interlock Bullets. The 350 grain RN Hornady Interlock was originally designed as a fast expanding medium game load for the .458 Winchester. Although various authorities suggest that round nosed bullets should not be used in tube magazines and insist on the use of flat point bullets, the 350 grain round nose Interlock has very soft lead. Even if an empty, primed .45-70 case is placed in a vice and the 350 grain Interlock is held against the primer and struck with a hammer, the soft nose of the Interlock does not ignite the primer. This bullet has very large scores in the jacket to promote rapid but uniform controlled mushrooming. The 350 grain round nose Interlock produces deeper penetration than its 300 grain counterparts but is just as good at producing fast kills down to impact velocities of 1600fps. For those wanting an all-round load for light through to Elk sized game of up to 700lb (320kg), the 350 grain round nose Interlock is a good performer.
The 350 grain FP Interlock is a relatively new bullet, designed specifically for the .450 Marlin cartridge in order to ensure safe operation in the tube magazine of the Marlin rifle. Like the round nose, this is a good all round performer, the only real difference being the omission of scores in the jacket which help the round nose to shed energy and eventually frontal area in a controlled manner.
