Have two 45-70's with different uses and need a hand in selecting factory ammunition. One has a scope that I use for shots 100 to 200 yards on deer and hogs up to 400 pounds( european) The other gun is used in heavy brush and comes with xs sights. This will be used for shots less than 50 yards on the same type of prey. If I had to go with only two typs of ammunition what would be my best choices. TY in advance.
