This is a friend of mine for years he carried a Rem 870 14" or 18.5" barreled 12 gauge that is until he first saw a Marlin 1895GS in 45-70 that he had to have he loads from 300gr to 550gr bullets for it.
Here he is shooting it @ a 25 yard target he does a lot of solo prospecting in remote wilderness areas of northern British Columbia, Canada and he always had his Chesapeake Bay Retriever with him until this fall when he had to put her down but he has a new chessy pup now that will be with him when he heads out in the spring.

His handgun of choice after spending years going thru trial and error looking for the ultimate handgun for bear defense is a Ruger Super Redhawk in 454 Casull shortened to 4.25" he installed a Crimson Trace laser grip.
When he is in black bear country he loads the handgun with 45 Colt 300gr XTP's or if he is loaded with 454 Casull loads he loads 240gr or 300gr XTP-Mag's.
He tells me when he is in grizzly country he doesn't mess around and loads his 454 Casull Beartooth 405gr WLNGC's @ 1330fps and he feels a handgun that is bigger is just to bothersome/cumbersome to pack all day and stated that the SRH/454 Casull is the best all round wilderness defense handgun he has ever found.
Here is a video of him playing around with 45 Colt 300gr loads and then 454 Casull 300gr loads.

He tells me that he has moved on in his choice of rifles after going in after an appr 1000lbs grizzly with the 45-70 he has decided that he wanted more of a all round cartridge/rifle combo so he shortened a Rem 700 LSS in 375RUM to 21" and did a few other mod's he is getting with RL17 powder 3030fps with 260gr Accubonds and 2740fps with 300gr Gamekings/Partitions/A-Frames.
These are not top loads but he tells me any more recoil would slow down his second shot to much if he needed one.
The rifle is set up with Leupold QRW rings and bases a VX3 4.5-14X40mm B&C scope and when he pops the scope off he mounts an XS Sights Tall Weaver backup ghost ring sight for his rear sight the front sight is a NECG Masterpiece banded front ramp and a partridge front post.
He has the 300gr loads sighted in dead on @ 50 yards when the ghost ring sight is on and the rifle is so accurate and the velocities where higher than he thought he would get from such a short barrel that he mounted a 4.5-14X40 B&C scope instead of the VX3 2.5-8X36mm B&C scope he originally bought for this rifle
Here is a picture of the rifle...
