Above : Marlin 95 45-70 easily converts to the 45-70 Whisper which has sub-sonic and high velocity capabilities delivering fine accuracy with bullet weights from 300 to well over 500 grains. And it is quiet. Shown in natural stainless finish many other color finishes are available.
The 45-70 Whisper is simply a 45-70 case cut back to 1.6″. The over all cartridge length was originally set with the 465 Grain Lehigh controlled fragmenting bullet loaded to normal 45-70 length to provide positive functioning through Marlin and other lever action rifles. In order to achieve excellent sub-sonic accuracy the short case –long bullet must be combined with a fast twist barrel to obtain the desired results. In addition the normal run of the mill 458 bullets may be used with “normal” 45-70 ballistics easily achieved while feeding reliably through lever guns. In testing we have often achieved around .700″ 100 yard groups with the 456 grain Lehigh controlled fragmenting bullet as well as with that bullet carrying a .224 “payload” bullet. Customers have reported much better accuracy than that on occasion. Impact with animals is producing exceptional results. With several accurate sub-sonic loads combined with SSK suppressors the noise level is quite low; rivaling much smaller cartridges. Other than lever guns the Encore and Pedersoli single shot rifles have proven excellent conversions. For reloading standard 45-70 dies work with the exception of a new seater die must be used. A hand seating die to seat the payload bullet into the hollow point is also availableSee Lever Guns
