So I bought a Tikka 260 CTR with the ideal of building a 280 AI. However I threw some loads together (139 Scenars/ 42 grns H4250) and after a quick zero, shot a .4 group. I decided I would postpone the 280 build and use it for deer hunting this season. I have been trying to work up a load with some 142 grn ABLR's. I've been to the range a couple times and the last 3 rounds I fired were 43.2 grns of H4350 averaged around 2550 fps ...slower than expected. I plan to bump the charge up to 43.6 - 44. I'm hoping for 2750 - 2800 fps.....am I asking too much for the CTR's 20in barrel and does anyone know of another powder that might get me more speed.

Yes, youre probably asking too much. Tikka’s are known to be slow, and your barrel is short. Reloder 17 is probably your best bet for more speed, but im not sure that stuff is available any more. I could be wrong on that. If you can get therewith your current powder, you’ll get roughly 50 fps going to 44 gr.
