I love my 1895G. It is short (18.5 barrel) which is good for the thick bush I hunt in. It is great to carry and could very easily be a great saddle gun.
For a 'bush gun' they are very accurate, Marlins' 1/20 twist ballard cut rifling handles 300gr to 550grain bullets, cast or jacketed, so loading options are many. Mine prints 1 inch groups @ 100 with a few different loads, my best was 1 inch 1/8 at 150 yards with skinner peep sights. I've mainly used 350gr Hornady bullets which have taken deer, bears, moose, no problem. Hardcast bullets (with wide flat noses) are good too and will shoot thru a bear lengthwise, I've used a 420gr Jae bok young's 'crater lite' bullet @ 1750fps to drop a bear this past spring. dropped him.
Midway usa has lots of bullet reviews (.458 has 6 pages of bullets with useful reviews) from customers, if yout decide to reload that will give you an idea of some of the bullets out there.
Its an even funner gun to load down and enjoy 'plinking' with 400grain bullets @ 1200fps. light and easy to shoot and accurate to boot.
If you get one you'll enjoy it.
