Having started out reloading simply because of the high cost of 7-08ammo I have caught the reloading disease and ended up buying a chronograph and spending time experimenting with seating depths, powder charges etc. I'm not a complete addict yet by some standards, however a year ago I wouldn't have thought I'd have bought a crony...
It was interesting though, some loads were a lot faster than I expected and some were a lot slower, here are a few results..
Nosler BT 150gn Average 2812fps Expected 2700
Amax 162gn Average 2551fps Expected 2650
Sierra 100gn JHP Average 3064fps Expected 3200
Berger VLD 168gn Average 2551fps Expected 2500
Federal fusion 140gn Average 2750fps Advertised 2850
So the load manuals can vary a bit in terms of what any given load is going to achieve, at least I know now what drop different loads will have and also where there is room for improvement in terms of velocity. Certainly the 100gn JHP could be pushed a little faster, whereas I am more than happy with the nosler BT load as it is.
