I had a 16" 243 mossberg patriot, its been through a couple forum members since.
With 2209 i got 85gr at around 3000fps with no issues. But their barrels are fast. In general you should be able to match factory 22" speed with handloads in a 16" at least though. Was a great little rifle that i regret selling sometimes but its been replaced. I used AR2209
