There’s many bullets for the 30-06 that will work great. I used to only shoot 180 grain bullets after a 165 grain bullet failed. But that was just an early design that failed. If I were shooting 180 grain now I’d think almost any cup and core would work well. If I were shooting 150 grain, I’d be looking more at premium bullets. I think you said you have 165 grain ballistic tips which should work fine as long as they’re not first production year bullets.
I had a suppressor put on my 30-06 and I shot a very nice group with it (<1/2MOA). It was with 180 grain interlocks. The suppressor not only knocked the noise down but also cut out recoil quite a bit. I’m hoping to get a few tags this year, maybe I’ll use that combination on one.
