As was pointed out, the site is called longrange
hunting.com so the 45-70 probably doesn't fit into that paradigm.
I have a few questions for you that might help the folks around here be more helpful to you:
- Do you want to hunt moose at long range or at typical hunting distances?
- Do you hand load?
- 338 H&H Mag? Do you mean 338 Win Mag?
- Will a hard-recoiling, expensive-to-feed magnum limit your practice time?
I hope you aren't getting rid of your trusty 30-06 to purchase this magnum! While she is an old caliber, there is a ton of ammunition to choose that is suitable for moose. From what I have witnessed, a well placed shot from a 270 Win is better than a poorly placed shot from a 338. That being said I would rather have a well placed shot from a 338
Your experience with a long track on a moose isn't that uncommon. You can't always fix that with a bigger rifle, though a larger diameter hole definitely helps. You are talking about one of the largest big game animals in North America here; they aren't that easy to kill quickly. If you recall field dressing your buddy's, their hearts are the size of our heads. Their lungs are enormous and take a very long time to bleed out even if large portions are destroyed.
My advice? Whatever rifle you use, make sure you are good with it
. Shoot them in the spine if you are close/confident enough. The spine is 4"-5" wide on moose I've cut apart so it's not impossible by any means. An experienced hunter and game warden I know advises people to drill them right in the shoulder at spine height. There is a lot of meat that will survive just fine and it will nearly guarantee immobilizing them. Lastly, if you hit them and it's not the "bang-flop" we all dream and hope for, don't pressure the animal. If they weren't alert when you shot them, they will often take a few steps, feel poorly and lay down. If you just give them their space and relax they will stay right there in most cases. If you get all excited and head over towards it often times you will give the animal the adrenaline surge needed to get back up and run.
Sorry if I sound preachy I'm just dolling out what little I know. Others will chime in I'm sure!
Happy Shooting & Happy Hunting
