RE: Good-bad-adequate
I take each bullet that I shoot and work with the powder levels until I find the best group it will shoot. Most of the bullets I've tried will group under 2" with the right powder load. The best I've found for my inline is a 348PB over 100gr of 777 2F that averages under and inch and has shot sub .5" on occasion with a scope. Without the scope the groups are about 50% larger.
I, like most, perfer to use the most accurate load for whatever bullet I use which is based on what I'm hunting. My theory is to eliminate as much variance out of the load so that the remaining factor is my ability. I use a basic front rest and a combination of a rear bag and my hand for the rear rest when checking loads.
I shoot a little better with a scope than with iron sights but that depends on what type of sights they are, some are harder to line up for my eyes than others.
I practice out to 200 yards fairly regularly at the range I'm a member of but thats the longest target site we have there. I sometimes go to another range that a friend is a member of and shoot out to 300 yards but that is not very often, they actually have ranges out to 1000 yards but I haven't got a chance to shoot on that one yet.
When shooting at game I will limit the shots to where my load will retain enough energy and accuracy to get the job done based on the circumstances the shot presents. If I'm shooting a very accurate bullet in a no wind condition that has plenty of energy at 200 yards and I'm confident in my ability, due to practicing at that range, to make the shot I will take it. If I'm not comfortable with the shot, I won't. Thats a decision that every hunter must make based on what is presented to them. Whenever possible I will use whatever I have, limb, pack, rock, etc., to steady the shot, even at close range if available.
