bullet caliber question??
 

I picked up a box of hornady FTX bullets recently. The same ones used in hornady leverevolution ammo. I tried the hornady factory ammo in my 45-70 and they seem to be an alright bullet for what I am going to be using them for. So I was looking in the manual for a starting load when I noticed something. The bullet diameter on the box of .45 FTX are .452". In the book the bullet diameter is .458".
So it looks like I bought the wrong bullets. I decided to look at the factory Leverevolution ammo to see if that was the case. The factory ammo measures .452" at the crimp. The box of ammo is marked 45-70 govt. So shouldn't they be .458" ? Can you use either?:scared: I've asked some of my other buddies that reload and they are stumped by the factory round measuerment also.
Anybody know?

Thanks

You can buy the FTX in either .452" or .458". You need .458" for the 45-70. I am suspecting that the shank diameter of the bullet in the 45-70 factory load is .458", but you are measuring slightly ahead of the shank on the tapered part of the bullet.

You have bullets for a .45 s&w or a .45 colt pistol. Take them back and get the .458.

45
