I'd be curious to know what game you've tried them on, because I have no experience with the 130gr BTs and very little with the 150gr BTs. I just know what I've heard about them coming apart easily. Always interested to hear first hand knowledge of a specific bullet's performance on game though.Never had a failure with 130gr Nosler BT
Right now I'm limited by the supply various shops in my area possess, which has thankfully left me with a couple hundred Sierra 115gr Matchkings for killing rocks for practice this spring and a handful of Berger 140s. I also have 50 Cutting Edge 120gr MTHs for putting big game down starting in August if I can't get anything else. I'll likely place an order for the 116gr AHs from Hammer just because I really like how easy they've been for me to get top shelf performance out of in the past with all rifles I've tried them in.170 Berger has been a hammer for me.. I like any bullet with the 270 but can't complain about the deer and elk I have laid down with a 170 elite hunter.. Although you do need a faster twist barrel.. Hammers are great you can shoot them with your current twist.. Pick something and get sending it down range.
