tp555 300 whisper barrels

Having done a little more reading, my conclusion is that if you are loading resized .223 like me there is not much advantage to a 1.350 as it's best for 221 brass that does not flow out past 1.350 when resized. A reduced chamber length and a long case can equal kaboom pretty fast and the advantage of a supported neck on a shor bullet is over shadowed by this IMO.

Make mine a 1.40 for safety reasons please!!
