The 30R Blaser is interesting but only holds 75 gr H20 vs 88 gr H20 for a 300H&H Flanged. None the less it supposedly can shoot a 200 gr bullet at 2600 fps.

The 300H&H Flanged maybe able to do that at 2600 fps and have more acceptable pressures due to case size although Kynoch data suggests they would limit 200 grs to 2500fps at 17.5 tons pressure.2600 fps would give a 4.5inch drop at 200yds with a 100 yd zero

Interesting!!
