With a 2.260 OAL you max at 27grains so would expect it to be a tad slow for 40s but probably achievable. Depends on the cases you are using but that is with a water capacity of 28 grains, but most of mine were around 30.
for a 28 capacity case that = 112% fill, with a 30 capacity case, you can get 27.8 grains before max. You will need a long drop tube. If you are after a cheaper powder look t Vectan or VV powders. I used a nice vv120 load with 40 CBTs and it was very accurate and getting towards 3800 fps.
