I shoot 130 Core-lokts out of my Model 70. I get less than 1" @ 100yds, so no reason to try anything else in my opinion. If you are getting good groups out of those PPT's I wouldn't change. Remington Core-lokts, Winchester PPTs, and Federal Powershocks are pretty much equal, just good solid performers. Boils down to what color box you like I guess. Every rifle I've owned I've shot core-lokts out of to begin with. If I can't get decent groups, I might try something different. Well, so far nothing but green and yellow boxes for me!

Oh yeah, except my 30-06. Shoots Core-lokts like a dream, but my wife read some article about lead fragments in ground deer meat and asked me to switch to an all copper bullet. Sure honey, I don't mind spending $60/box for Barnes Triple Shock.....

Now those are some sweet bullets, a bit of a step up from CoreLocts. So I splurged a little...you only live once.

Splurge away....
