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

I wonder if the old loads for 270 (e.g. H4831 was the go to) had a lot of unburnt powder AND the consequent high muzzle pressure. Back in the mid 1990's chronographs were rare, and the internal ballistic data we have via programs like Quickload didn't exist.

My Quickload is down just now (must revive it) but there's no need to blow unburnt powder out the end of the barrel these days. I used it to produce a very mild report load (unsuppressed) for my 22K Hornet, by selecting the right powder I was able to drop the pressure at the muzzle from 7000 psi (many powerful calibres chasing velocity run at 11,000-12,000 psi) to a bit over 4000 (this was in a single shot rifle with a 26" barrel which does give more options to play with loads).

Cheers for that. Very useful.
