Need some figures run please

I wonder if someone with a ballistics program could run some numbers for me.

I'd like to know the approx. MV of a 140 gr. SMK over 46.0,48.0,and 50.0 grains of Re 22.

6.5-284
Lapua brass
Fed 210 primers
26" barrel

Any help would be appreciated
Chris

Re: Need some figures run please

Assuming your touching the lands, & bullet shank seated .26 into neck:
48gr= 2720fps (~47kpsi)
50gr= 2820fps (~51kpsi)
52gr= 2920fps (~57kpsi)

This from QuickLoad.
SAAMI max =59kpsi

Thanks Mikecr

I'm actually .010 off the lands and quite a ways into the case neck. OAL is 2.965, 3.465 on a stoney point comparator. But at least I've got some ball park figures to start with.
Thanks again
Chris

The reduced starting pressure offsets the reduced case capacity w/regard to pressures, and velocities should remain very close.
