Barrel Lengths

I dunno why, but over the past couple weeks, I got the hankering to buy a marlin 1895 45-70 for bear hunting in the spring.

My question has to do with the barrel length,

Marlin 1895G has 18.5" barrel.

What would be the aprox muzzle velocity lost over a 24-26"

Keep in minde I will be using this in the 100-150yard range, basicly a big bore "bush gun."

    I still haven't figured out why people think big bore, heavy bullet, slow ***** cartridges are good for bear hunting, a properly loaded 308 with a 20" pipe will hit just as hard at 50 yards. But to answer your question, with the fast burning powders used in a 45-70 there is little to be gained in 6-8" of barrel. The fact that the 1895 is a lever gun is more of a drawback than the barrel length, cowboy guns simply won't take the pressures that you can load to in a single shot or bolt gun.

    i agree, you might loose 100 fps. a 45 has a very high expansion ratio.

    I dunno why I am explaining myself but here we go:

    And I totally agree with you, but my 300wm is not suited for the bush at a OAL of 46", and a Marlin 45-70 with a OAL of 37" seems like a logical choice for me considering the price.

    Normally I use my 300wm with 200gr Accubond (does wonders), but looking for something new/different this time.

    I understand the problems with the pressure in the lever actions. I have been going over my books and firgure that 2000+ fps will still be atainable with a 350gr pill.

    Tks for answereing the question on barrel length, good to know.

    Well another 2 good options is savage offers the model 16 bear hunter in 325wsm and remington made a new run of model 7s in 350 rem mag, they both seem to be popular among bear hunters . My point was that 350 45 cal bullet ever at 2000fps has like a .23BC so it runs out of steam real quick. In the marlin I'm a fan of the 444, imo its a little more potent, but its your decision, just throwing out some ideas.
