[QUOTE="BountyHunter, post: 229143, member: 12"] The key to this is the long throat setup just for the 190s. This moves the bullet well out forward from the standard COAL and increases case capacity from the norm for that weight bullet while lowering pressure due to the increased case capacity. Not sure of the actual numbers, but anyone with quickload can see the effect themselves by adjusting the the default settings for seating and OAL in QL and watch the MV go up and the pressure down. that is also why beware of internet posted QL numbers because they are normally run from default figures which if you are deviating from the "established norms", and you do not adjust in QL you will get bogus figures from reality. If you trr to do this with standard 308 reamer, you will screw up as you will be short in the throat, you must go in and hand throat out to max OAL for the 190. Dave Kiff of PTG makes a really good hand throater that is easy to use. BH [/QUOTE]
