Re: Anyone tried GS custom bullets
This is Gerard's reply for your guy's intrest. my bullets will probably be travelling at around 3200-3450fps from my 30" brl.
The BC numbers for all our bullets are calculated with the software developed by McCoy for the US Military and therefore represents a constant number for all our bullets. Where your particular atmospheric and geographic situation shows a practical difference, up or down, the difference can then be used as a constant multiplier for all our bullets.
The numbers for the 264110SP are:
3300fps - .665
2250fps - .593
1200fps - .433
The bullet is designed to have a stability factor of 1.22 from a 1:8" barrel at 3000fps. Tractability is very good and, depending on conditions, will enter the transonic zone at about 1200m
