Re: Why I will be hunting long range with a little help
Welcome and congrats on working through your disability. LR shooting/hunting is very rewarding and I hope it works for you.
Same thought, get a longer barrel (30" min, taper if you want to save weight) and increase rifle weight. I have a 36" RUM in a 35lb rifle, muzzle brake and it still moves back 1" under recoil. I can still spot my shots which I feel is important for LR hunting.
I have a separate block of steel I bolt to the bottom of the stock. The orig rifle is 20lbs. At 20lbs, the recoil is not for me and there is no way you can spot your shots.
I also suggest you look at the NP2 reticle. I have mildots in all my scopes not because I use them to range but so that I have some reference for spotting and adjusting.
When you see a bullet land 'a few feet' from where you aimed, adjusting takes time and is not always accurate. Just how many inches/feet away was that impact? hard to judge at 1000yds.
With the reticle, you can compare the impact with the reticle and just move over. When you start shooting in the field, you will understand what I mean.
Also, super high mag is not required. Like Ian suggested the 22X is going to be lots. Elk are pretty big even at LR. You want field of view to keep track of the elk you want and its relations to other animals/geography. After the shot, you need to see where it went.
I would be surprised if you used over 16X under hunting conditions. Most of my shooting at 1000yds is at 12 to 14X depending on the scope.
Keep an eye on stock design. I prefer a flat bottom BR style. You want something that rides the bags well and will not roll during recoil. Stock design makes a huge difference on your ability to shoot well.
Finally, practise, practise, practise. Shoot at LR as much as possible. It would be nice to have a lesser cartridge to practise with. However, the only way to know how your rifle and load works in the field is to shoot it in the field. Barrels are easy to set back when necessary.
I would lean towards the 220gr MK or 240gr MK. At ranges beyond 900yds, any increase in horsepower is desireable. Also, the better BC will help with wind drift. You could also look at the 200gr Nosler Accubond.
