What type of hunting are you planning on doing, with your current situation I would say settle on one load for all your hunting. Buying factory ammo for the Whelen will be a little more expensive and there aren't that many factory loads available. I would say the Federal 225 TBBC is probably the best choice as a one load for everything. Nosler has a 225 gr partition load but finding someone who carries them and at $40 a box that's a little pricey. Save all your brass. I handload 200 gr Hornady interloks and corlokts using 4064 and get sub 2" grp on the average. The 200 gr Remington factory loads were at 4".
