.475 Linebaugh

The 475 is a true big bore that offers real big bore punch and high velocity in a practical, packable package. This conversion is done on new Ruger Bisley™ Revolvers ONLY! We fit a new oversize 5 shot cylinder to the Ruger frame with a true .475 bore barrel. Chambers are cut tight like all our guns for a minimum of brass working. Over-all fit is held to a minimum that still allows guaranteed functioning. Cases for the 475 Linebaugh can be made easily from Winchester brand 45/70 cases. Cut and trimmed to 1 400" long finished length the brass is ready to load and fire after minor expanding. The availability of factory brass and ammo supercedes this wildcat forming operation. Case life has been excellent with this round despite its 50,000 psi maximum operating pressure. With 7 1/2" barrel you can expect the following velocities:

 

325 gr. LBT cast   1700 fps   37 Knock Out

350 gr. LBT cast   1600 fps   38 KO

400 gr.LBT cast    1400 fps   38 KO

420 gr. LBT cast   1350 fps   38 KO

 

Accuracy to date with this round has been near 1 1/2" at 50 yards. We have obtained 4" groups at 100 yards with machine rest but do not guarantee this type of accuracy to each gun. This is a fairly violent round, and recoil is heavy and very sharp with top end loads. Gun life is excellent if it's kept tight and oiled on each end of the cylinder. Bare steel on steel will batter and soon loosen a gun. Oil on the ratchet and nose of the cylinder will go a long ways toward insuring a tight gun. Fit, finish and function is guaranteed. Load data is supplied with each gun. Hodgdon Powder Co. has a full listing of load data for this cartridge in their latest loading manual. H- 110 and W- 296 are used exclusively for top end loads. Hodgdon's HS6 is good for medium and low velocity practice loads.

 

For the ultimate on big game, this packable package in .475 caliber is tops. Any major caliber 357, 41, 44. and 45 caliber handguns will work for any of our conversions
