Hey Longwinters,
I would guess you already know this, but from everything I can find out, the balistic tip is best left for targets or varmits until you get to the .338. A friend took a black bear over bait with a .338 BT and it held together well even at the close (well under a 100yds.) range, and my reading tells me the bigger ones are tougher.
When I read the Nosler book, they never will say that the BT is up to hard use such as the Partition. I have read and re-read the info hoping to find just such info because of the rep. the BT has for making small groups.
However, from personal experience, I can sing the praise of the Partition. Have been using them for over 30 years, and have seen times when they should have made a mess and didn't, yet they always did what they were sent for.
Some people may think that because of their rep. for penatration they won't expand on small game animals. WRONG! The front end is made to open even at longer range/lower vel., while the portion behind the partition keeps on truckin.
The few expended bullets which I have been able to find in game, almost always, are minus most or all of the forward portion of the bullet. Maybe there would be more bullet left on the heavier calibers, but on .30 and below the above info would be correct as per what I have seen and read.
I have personally gone to the 165gr in my 300 win. mag. even though I usually like to go with the heavier bullets with the Mag. However, the 165 shot the best, so am getting 3250 - 3300 over the Chrony. Would not trust that wt. bullet at that vel. with something of less quality then the Nosler Partition.
Keep em coming! :wink:
