243win to 260 rem
 

OK i have been shooting a 243win 100gr hornady interlock spbt.
I love the performance and all on deer,but i am going to a 260 rem
and am wondering how the berger 130 gr hunting vld hollow points do up close.Lots of my deer are inside 50 yrds.I have had one shot kills out of the interlock but the dont make a spbt in the 260.So am i gong to have any issuses up close?

I would stick with the bullets you know that work. The Hornady Interlock is great on game like deer that don't need a super-premium bullet. That or the Remington Core-Lokt would work just fine.
