Today I was blessed by a young man that let me use his chronograph.
.303 British 125 gr. sierra pro hunter behind 46 grs. H335 only gave about 2650 were as the book stated about 3,000.
S & B factory 150 gave almost 2700 fps.
Privi 174 bt factory gave about 2450.
I'm wondering why I only got 2650 with a max load of H335 with a 125 gr. bullet?
Any input would be appreciated.
