coop,
I have found that 20.5 grs of either 110 / 296 shoot very well with bullets from 200 - 220. I use WIN/ WLP primers exclusively with these loads. I trim all cases when new, and then check lengths after every other loading.
Don't get too caught up in the " very heavy crimp " with your loads. I have been shooting 7.5" Redhawk this caliber for better than 20 years and have found that with just enough of a crimp to actually roll the lip of the case over into the grove of the bullet, you will get your best accuracy and not be slipping any bullets. Also when you size your cases you want just enough bell to actually be able to feel it with your fingernail, Much more than this will result in early split necks.
With my loads, 99% of them are loaded for hunting and will group tighter than I can hold out to 100yds. I shoot them on almost a weekly basis and the bullet you chose is a good one. I shoot the 200gr JHP from Remington but it is simply a personal choice. Either will dispatch the hogs readily.
