180 Rem Core Loc in my Rem 7400 30-06 have always been my choice ...but also depends on the terrain and the shot distance your trying to shoot...if you want distance and a flst trajectory try a 160 grain boat tail bullet..good hunting
my 30-06 shoots great out to 200 yards with, 230 gr. remington cor lock, or 220 gr. cant think of the actual weight for some reason. but, i like the heaviest thing i can throw at a deer, if i could shoot boulders at them i would. maybe i need a catapult? for some reason i dont think corzine would approve of that
Test different grain and manufacture in your gun. What works out of one gun, might not workout of an identical gun. I spent sometime at the public ranges this year, watching guys sight in there muzzleloaders and slug guns. I realized that many guys out there don't have a clue at how to sight in a gun. They staple a target or pie plate to wood and if they can hit it at a give range then thats good enough. No rests, no grouping, no dialing it in. If it hit the target that good enough. I like to play around with the gun and see what it likes. I did know that my muzzleloader loves 110 grains of powder (2-30 grain pellet and 1 50 grain) it hold 1 3/4 groups at 100 yards. With 150 grains it shoots 3" groups... imagine that and I don't feel short changed by not shooting the max. Accuracy over knock down power, anytime. Sighting in is fun, not work. Enough chat for now, get a ballistics book and practice around with different loads.
My deer rifle is a .270 with 130 grain Boattail spitzer. I have whacked (the sound it makes when it connects) them out to 350 with it. Yes, I use a rangefinder. Yes, I use a mil-dot scope. Yes, I hand load.
30 caliber is a excellent choice. They have the widest range of bullet wght. to choose from than any other cartridge.I have found Federal ammo through the years to shoot best out of my rifles.150-180 grn would make for good deer medicine.
