The heavy-jacket Ballistic Tips (which as mentioned earlier started with the 200-grain .338 in the early 1990s) were indeed much tougher, and the jacket was a LOT heavier.
John,
When did Nosler stop offering the BT’s in .338? (other than the current Silver Ballistic Tip) Is my memory fuzzy or did they also offer a 35 cal Ballistic Tip at one time?
