you may have to drop down to the 129s to get the speed you are wanting.

How far is the typical max distance shot where you hunt? If 300-400 or under, that 2550fps will be plenty.
I wouldn't go any more over 44gr H4350 with a 142, actually I wouldn't go much over 43.0 if it were me. You have got to be at max.
You might want to go get about 100+ rounds down the barrel and get it broken in. You should expect about 100fps speed up from new to 100+ rounds down the barrel. Also, 2850 in a 26" will be about 2700 in a 20". You are asking an awful lot out of a 20" pushing a 142 @ 2800. Try RL26 if you are trying to wring out max velocity.
Looking at your numbers, .4-.6gr of additional powder are not going to get you 200-250fps more anyway.

As pointed out on another forum you posted this question - 1) Tikka barrels known to be slow and 2) the 20 inch barrel loses velocity over the 24 or 26 inch barrels.
You might try Winchester STABALL 65 - it seems to be a H4350 alternative and seems to provide more velocity. (I bought STABALL65 back when H4350 was unobtainable and used STABALL 65 in 260 and 65CM).
If you are deer hunting, the 142 ABLRs are specifically designed to provide terminal performance at lower impact velocity. Let the ABLR do its thing. Maybe switch to the 129ABLRs if you want more speed.
I have a Tikka 260 CTR 20 inch also and it shoots great and I accept the slower velocity for the tradeoff in barrel length.
