Re: can a reloud make fast?
Please, please, please tell me English is not your primary language.
I'll take a guess as to what I think you're asking. 1) Do reloads give you more speed than factory ammo? or 2) Can you reload for more speed?
1) It depends. But it is certainly possible and fairly common. 2)Yes, with the caveat that more speed doesn't necessarily give you more accuracy.
If you want more speed, you've left out critical information. What caliber? What bullet? What powder? What are the rifle specs? What ammunition or loads are you using now and what is their chronographed speed from your rifle?
