I was starting with Accubond 180's, but sounds like I should consider a heavier bullet. My Nosler chart says H1000 is the most accurate, so I started with 79 grains. Shooting 1/2 MOA @ 100. Haven't moved out yet. Maybe this weekend. All ears.
Well you got enough gun to get the job done, now you need a good bullet to get to the target.. that's the hard part.
As for most accurate loads out of the book(s), that's always been a crap shoot. If you really want to know what's going on with your load(s) and the rifle,(and you should if your planning on long range shot's) you have too have your own chronograph; guys that try, and those that do punch critters at longer ranges have to know what the rifle and load is really doing out there in the anything can happen zone.
All in all it sounds light you might want to get into the 190gr to 215gr quality game bullet, then put it on paper "at" the range you plan to hunt and those would like to hunt, those longer range's you mentioned. Find out what's going on in the mechanical accuracy department and your shooting skills. Then crunch the real numbers, that's where the chorny comes in, find out whats going on with the bullets; internal, external; and terminal ballistics... then go find some meat.
Good luck, hope the hunt work out.
