My wife uses a savage 110 in 243 for deer. I've had her using remington core-lokts for the last 2 years. I've been talking to alot of people that are telling me that I should switch to the 95gr. Nosler BT. Is this really an adequate bullet for deer. I'm more worried about expansion than anything. I have used the BT's in my 280 in 140gr with no problems. Just wanted some input on the bullet for the 243.
