[QUOTE="nkyshooter, post: 2101104, member: 83787"] The "large" cartridges that hold "lots" of powder is how we get bullets moving "fast" ... but they need the longer barrel length to achieve it ... by going shorter, you give the powder less time to work, therefore you have to go with faster powders, which means you will reach max pressure more quickly which means you have to not put any more in which means lower velocities ... The Factory cartridges that are closest to what you're trying to accomplish are probably going to be the 6.5 PRC, the WSM's and the RSAUM's ... but you will loose enough velocity by going that short that you will need to move into the wildcat space which means you will have to reload or have someone else load for you ... 6.5 SS wildcat may be your best bet for what you're trying to do ... If you care about powder efficiency (not everyone does - but I do - particularly when components are scarce and slow powders are a challenge) you might want to look at a custom throated 260 ackley and/or 7mm-08 ackley that will let you seat heavies long ... they are shy of the performance of the 6.5 PRC in the 26" barrels ... but ... at 20" barrel length, you may find they actually OUT perform due to that efficiency and abilility to burn faster powders with less pressure problems therefore losing less velocity per inch of barrel forfeited ... Best of luck with your build - nothing better than building a rifle and watching it come together and hitting distant targets that first time! [/QUOTE]
