Thread: 243 twist rate

Hey Cigar
I’ve used 1:10” twist .243s for many years, a CZ same as yours (my first centrefire in the 80s), various CZs and Tikkas and now a Howa which is the best one yet. The one pill they all shot really well is the Sierra ProHunter 100gr (1540). Half MOA, reloaded in Lapua brass with AR 2209, 20” barrel. I run them at 2800fps out to 400m.

This pill puts down reds with ease, its a frangible bullet so very effective at spreading the message through the vitals. I don’t heart shoot, I go for the front lung / CNS shooter (autonomous plexus) drop ‘em on the spot shot, also the neck in certain circumstances. The Sierra has been probably the most reliable killer of the bullets I’ve tried. You won’t get an exit very often, all the energy is used in the chest cavity, I very very rarely get a runner that goes much past 10-20 yards, 9/10 drop on the spot.

I’ve put a few guys onto the ProHunters over the years, don’t think anyone has struggled with stability or accuracy. Well worth looking at.
