Thanks for all the feedback and debate, this is the advantage of a forum such as this, you can base your decisions on the experience of others rather than bumbling around in the dark chasing your tail and getting nowhere. I am going to order some 225 grain Hydrostatic and some 225 Barnes TSX projectiles today.

Received this email today for Geoff from Woodliegh

Price of 35 cal x 225gr Hydros is $47.40 per 20 plus postage.
BC undetermined at this time.
No significant extra drop over pointy bullets to 200M.
Seat to suit magazine length and throat.
Use SN load, pressure and velocity very close.
Some Mauser 98’s won’t feed properly.
It’s a matter of trial and error.
Regards,
Geoff McDonald

Thanks again for all the assistance
