7.5 twist in 6BR ??

[Jojo]

Hi everyone,
I have been offered a 6BR Kelby Panda /Bartlein 26" 7.5 twist, in a McMillan A3 adjustable, for 300-600 F-Class, that has shot all of 21 rounds,genuine). The guy has suffered health problems.
Now, all the shooters I know who own 6BR rifles, and all of those on this forum seem to prefer the 'holy' 8 twist for the 105-108's.

Will there be any problem with a 7.5 ?

I'd imagine over-stabilisation is no bad thing ? As long as jackets are thick. I suppose the faster twist may steal some velocity ?
What about shooting 90-95 grainers in this barrel?

I guess a possible future re-chambering for long throat Dasher will allow 115 DTACS ?

Any advice appreciated !

I don't think you'll have a problem. I've shot a 223 quite a bit with a 1-7 twist and it'll shoot 52- 80 gr sierra bullets. they all shot .3-.4 moa. I think like you said you'll lose a little velocity but thats pretty much a mute point. keep us posted.
