I'm wanting to have a new weapon built for me. I'm still in the planning stage or dream mode and I need some help. I am wanting it for deer and Target use and long range predators. I also walk, alot when I'm out in the woods so it can't be to heavy. I would like to be able to get out and reach them on paper at 800 to 1000. And out to 500 on deer if everything is just right.7mm mag is what I'm going to use for the round. And I like larson 7000 with a jewel trigger as to that is the only custom gun that I have got to shoot. I like the sniper stocks and a removable mag in there also. I am new to this so I don't know what's good and what's junk so any help would be great. Also what would be a good barrel,length,contur, rifleing, ext... And I think I want it in ss but nothing is for sure but the 7mm mag.
