Thread: How much does a 270Win suck in 2019?

At 22" the pressure is up to 13,500 and only 94% burnt. If you compare this with a "modern" tuned load of a 120 gn in something like 260 with N550, the muzzle pressure is 9500 psi with a 99% burn.

@Tentman So just to clarify, are you saying that less muzzle pressure gives lower recoil and muzzle blast than that of a load with the same speed but a higher muzzle pressure?
