you may never get there with whats available to us.
And it won't matter anyway. 100 fps isn't enough to sweat over. I"d take the 2950 and be just fine as long as its accurate enough.
Run the drops/drifts and you'll find unless you are running Long shots, it won't matter enough to worry about.
That being said the way I get to most MV... odd rifling, not even. chamber for the loaded round, IE cut to match. Coated bullet and coated barrel with something... nitride,ceramic, moly etc... and high energy type powders like Viht N500 series.
