As I have stated in other articles, my Marlin 45-70 SBL is my brush rifle for deer, black bear and moose inside of 100 yards. For black bear over bait, it is well respected by black and brown bear guides at close range. Not for longer range like my upcoming buffalo hunt. For that, I will use my .375 Ruger.

As a 45-70 handloader, you can independently work up loads or work them down. I have several loading manuals to cross reference. 

At issue by some hunters is; who made it, when it was made and its chamber pressure. Weak trap door models having very low chamber pressures and muddying up the power of the 45-70 in hunting circles.

Todays 45-70 Lever rifle is not yester years 45-70. 

My Marlin 45-70 SBL (Stainless Big Loop) has a very strong modern action and is made in the USA by Ruger.

In Ruger, I Trust!

Good Hunting!
