I personally think your making a small mistake not hand-loading , as it will significantly reduce the cost of ammo and pay for the cost of the required, reloading equipment rather quickly.
I would not be a bit concerned if the bullets exit the deer this allows a much better blood trail if (the deer were to try to run after a good hit.. very unlikely,)
now I fully admit that I tend to be far more interested in hunting Elk than deer, but I recently purchased a 450 marlin BLR just because I found one on sale and the fact that my late hunting partner used a BLR in 358 win to kill over a dozen elk, and I know he never shot one at over 200 yards) did not hurt my expectations either.
the best load I found so far is not near the max level, its a 405 grain remington, bullet over a 215 fed primer and 50 grains of IMR3031
1.5" 3 shot groups are very common, with that load.
my rifle looks very similar to this picture I found posted
factory ammo costs between $1.60-$3.00 a shot, reloads would be less than $.70 to as low as $.50 each, on average
saving $15-30 a box of 20 cartridges will pay for the loaded ammo and reload equipment fairly quickly... especially if you get a deal on some used reloading press and powder scale etc.

ID suggest you buy a couple GOOD QUALITY RELOADING manuals and read through them,(ILL LINK a few of THE GOOD ONES BELOW)
before you buy any tools, or supplies but its just not all that difficult, but yeah better understand the process because mistakes can potentially be dangerous, these three are very good
http://www.midwayusa.com/product/93....ProductFinding
a good single stage press may be comparatively slow, compared to some progressive designs, but with the correct accessories will load almost anything, in the common rifle or pistol calibers.
quality press
http://www.basspro.com/RCBS-Rock-Chu...duct/10200311/
decent powder scale
powder measure/dispenser
get a basic press , powder scale, powder measure and DIES, shell holders and some reference material too start
THEN READ at least TWO GOOD MANUALS CAREFULLY
shell holders
DIES FORE EACH CALIBER YOULL RELOAD
