"I should get the other BOSS as well?"
I was thinking the WSM could take the place of the .308 for woods deer work. But now I see how much longer the WSM is. I didn't know the .308 Stalker barrel is 20" instead of the ShortTracks 22". So as Emily Latella said, "Nevermind".
But if you don't think the WSM kicks you can use the unported BOSS and make it quieter.
The standared caliber Stalkers like mine have 4 rd mags. The magnums hold 3, and the WSMs hold 2. Some of the ShortTracks and LongTracks hold less because of the composite magazine cover, strange. That hinged magazine cover keeps you from using a longer mag like the Remingtons can. I've never heard of anyone changing the mag catch and adapting other magazines. It's not a battle rifle anyway, although the .308 is several pounds lighter than a M1A.
