[QUOTE="ARlife4me, post: 2592198, member: 105694"] Depending on bullet weight and powder used (charge and variant) can lose or gain velocity on barrel lengths on caliber choice. Say you take 60k psi at the 1st 2" and it all gets less the further down the tube it goes (we all know this, right). Some powder doesn't produce as much gas volume as others, but all are typically equal at throat and just past. 24" is a good over all length, but might be the best? A friend of mine has an 18.5" 7-08 using 140 or 150gr bullets. It's accurate and uses it up to 500yards on deer and elk. If hindsight were in play you could know what would be best choices are.
