Huvius,
To shoot at only one target at a useable range takes too long to locate the point of impact, you need to shoot the second shot as quickly as you can get back on target. The purpose here is to see how the rifle shoots with the load in question. When in the field,you may very well take longer between shots and not let the barrels cool.You are doing two different things.I usually shoot at around a hundred yards,sometimes eighty.Unless you are checking shot patterns, 25 yards doesn't seem like a good distance to use.Again, you are checking regulation,you may very well have a 25 yard shot while hunting; but first you have to find the right load.
On the other hand, this is your rifle,not mine. You are perfectly entitled to do what ever you want with it.As long as the shells hold out,have at it.I won't get into bench technique.
Mike
