A good load for deer is: Hornady 150gr SP using 42gr of IMR 3031 with CCI 200 primers (good luck finding primers!). 42gr of IMR 4895 will give you +/- 2500 ft/sec. Use the above at your own risk. Don't forget, you have to use "Britishicon" bullets (0.311") not 30 cal. It's a good idea to have several reloading manuals for comparison and always start on the "low" side.
