Re: 7mm Magnum loads
quick note on overheating the barrel as well- even though its fluted, you shouldnt have to worry about it at all really, especially while trying loads at the range. as the barrel heats up, its going to change your POI, so to ensure everything stays consistant, let the barrel cool a few minutes between shots. what i do is shoot one, walk down range and mark the shot, then go back and check the barrel before shooting again. not that i really need to check the shot every time, but walking 100 yards down and back gives the barrel a few minutes to cool and me something to do while i wait. if you shoot too fast in between, its going to throw your shots- mine usually happening in a rising string at about 45*. yes, it takes a while to try loads out, but shooting fast does you no good anyway.
see how much better this is when you act civilized? you might start shooting halfway decent after all....
If it were easy, I wouldn't be doing it.
