short barrel 300 load options

[86alaskan]

So, I'm running a Tikka T3 boar hunter with the 21" barrel and a silencerco omega suppressor. Right now I'm using a sierra 165gr game king and running in the 2850fps range with IMR4350. My question is this.... anyone use a faster powder and get better velocity from a short 300? I'm also wondering if a re-barrel, to 300WSM in that length, would gain me anything other than a more expensive barrel. I don't need heavier bullets to kill deer with, so I'd like to stick with the 160ish bullets as a compromise between weight and velocity potential. I'd also like to stay with a 20-22" barrel to keep it handy with the can on.

The powder that produces the best velocity with a long barrel will also produce the best velocity with a short barrel.

something like rl22 or h4831 will likely be your best speed/ accuracy with a mid weight pill in a 300win...
