Some people might have better answers than mine here but herer is my thaught:
- If you want to achive maximum speed with a good 6.5 mm bullet, you should go toward a 107gr scenar or matchking or 120gr scenar or matchking.
I have not ran my balistic program for these but out to 300 yds the 107gr my out perform the 140 gr MK or scenar or 155gr(no longer made but sometime still available) in term of speed.
-I do not understand well the second question:
Do you want to reduce the case capacity so that the 190 gr bullet become the heaviest load at subsonic velocity with maximum of powder?
or do you mean just shooting a 190 gr at subsonic velocities in a 1 in 10 barrel? (for the later that should not be a problem).
- I do not t6he answer for question 3.
