Thread: 270 and superformance

I've used 2213/4831 for a number of years, works great, nice and accurate. Then earlier this year I tried some 140 Interlocks pushed along by Superformance. Didn't do much load development - it is a 270! The Superformance loads are just under 200fps faster, just as accurate, with less pressure signs. So now I have a new go to load that is accurate and hits like the hammer of Thor, cant ask for more really.
