Actually, I buy 240gr JSP's when they're on sale - then I buy a bunch ! (like 250-500 rounds)
A "bunch" will last me for quite awhile - but I'm looking for another "sale" right now, since I'm down to about my last 30 (Magtech) or so rounds from the last sale. The Remingtons, I had B 4 that, lasted a couple of years. (I rotate my hunting among several rifles of different calibers - Monday gun, Tuesday gun, rain gun, stand gun, etc, etc)
I've found that there's not much terminal performance difference between brands, unless you opt for premium ammo/bullets - like Garretts, Buffalo Bore, etc.
The supposed "accuracy difference" between brands is closer than I can shoot at 100yds with iron sights.
"Point-of-impact", however, is another thing - new/different ammo most often requiring re-zeroing.
