lots of guys seem to prefer shorter barrels, but my .204 not only had a 23" barrel plus D-Tech comp. on the end, now I took the comp. off and added a 7" suppressor, and it works just fine for me.
If you should shoot at moving/running targets, the heavier barrel will help you with follow through. And a longer barrel will help get the muzzle blast away from ya, just a little more. Also, you get the better performace of the caliber with the longer muzzle.
