I just picked up a 35 Whelen barrel for my NEF. I have it sighted in but thats as far as I have gone with that project. I think the BLR is the only thing chambered new in the 358. At least thats all I have seen. Its a bit of a mystery to me why the 338-06 has not enjoyed much popularity as its a great round. The Encore is the best way to go for a 338-06 and I believe the chamber the 358 as well.
