Yes 32.5 gms is over 500 grs. Though it is written as 325 grs. If 325 grs projectile who on earth makes a 325 gr projectile? Woodleigh does make 320 grs.

Also the Hornady FTX projectile is not available in 9.3mm and is also a boat tailed spitzer projectile not very suitable for a double rifle.

Obviously a similar level of quality control and effort is made test shooting, and recording on the target to making the rifles.
