I'm stuck in a quandry at the moment. Currently I use 210 Fed match primers in federal or lapua brass with 51 gr varget and 150 hornady spbt. My problem I think is that I need a faster burn powder for the shorter barrel as I'm getting quite a lot of muzzle flash even with reduced loads.
Anyone use a 22.5" bbl if so what powder would you recommend for somewhere near a correct burning powder with 150 btsp?
It is quite a while ago since I have loaded 150 grs bullets in a .30-06, but when I did, I used RL15 with good results.
22.5" is not a particularly short barrel for a .30-06, in fact for many years 22" was considered standard for anything smaller than magnum calibers. I have only got very limited experience with Varget, but judging from burn rate charts, I doubt you need anything much faster than that.

You will have muzzle flash with that lenght barrel,but so what! If you down load,then your losing the effectiveness of your cartridge! Then why have that cartridge,its like stepping down in size. all barrels have muzzle flash,just as not noticable in the daylight as some. vangunsmith

I was just emailed some data for the Barnes TSX from Barnes customer service..The most accurate load for a 150gr TSX is with H4895.A max load of 51gr gives 2975fps (load density is 91%).

Using a faster burning powder in shorter barrels to get more performance is a myth. The best loads for 26" barrels are the best loads for 22" barrels. Go to the Nosler reloading manual for the best available loads (e.g., ~60 gs. of IMR4350 with 150 gr bullet should be a very good load, although close to MAX). Re19, W760, and Vv550 should work well with 150 gr. bullets. For 165 gr or better, I'd use Re22, MRP, or WXR.
