Not sure how I missed this thread so long. On receiving a free 336 as described .... YOU SUCK! grin

On the 220 speer ... it has a rep for being tougher than other Speer bullets. Not sure why that is and haven't ever used it, but I've been tempted to in my .358 Win and .35 Rem. The .35 Core-Loct RN also has a great reputation and I've got Boo Koos of them for my 1950 336SC .35 Rem. So far I've only run Hornady 200 gr Interlocks in my .358 Win.

Hope you get a Nilgai and report back. They're supposed to be some tough beasts so should provide a nice test for the 220 speer.
