Hornady 7 PRC a Lie?

Too bad in the 50s they didnt design the throat for bullets that didnt exist.

If you dont want to handload ammo, a custom twist barrel, a custom chamber, and a custom mag box theres obvious benefits. Plus going faster with less powder doesnt mean anything either.
I'm not running out to buy anything PRC. Reckon I can get my killing done with what I have. mtmuley
 
Just like years ago with WSM now the fad is PRC
FACTORY ammo speeds are always embellished by 100 to 200 fps sometimes even more
 
My 300 wsm shoots 165 gr speer spbt at 3250, no jacking the speed there. 180 gr at 3000. I've never owned a seven mil, but have shot the O'Connor for a few yrs.
 
Just to clarify, I was saying you can get 2800 out of a 280AI, at least according to Nosler reloading data.
My experience supports this. I’m getting 2950fps with a 180gr VLD from my 280AI. It has a 27” barrel, so I would say 2800-2875fps should be very doable from a 24” barrel.

It’s doable. 175 partition at 2850 from my 24” 280 AI. Long bearing surface on those partitions.
 
The velocities posted by hornady are based on the SAAMI specs. I know for the 7PRC the barrel length is 24 inches.

Ron Spomer did an interview with Seth from Hornady explaining what is going on with the lower velocity some are experiencing. Mostly is the availability of the preferred powders are not available, mostly going to the war effort in Ukraine. Hornady is having to use other powders that just arent getting the velocity. Very good interview you can find on rons podcast on youtube.
 
I’ve seen this “they lied to me about velocity” argument before. I have a 7mm SAUM.
