Re: Lazzeroni velocity?

Quite possibly when the case size quadrupels there may be a differance.????

Reload your own. I shot a 165 grain Hornady Interbond at 3500 fps this past hunting season out of my 300 RUM. 3600 - 3700 fps is probably attainable with a 160 grain bullet. Your barrel may not last that long, but you'd be right up there with the Lazz...

I doubt it as the highest velocity loads I have seen put it about 3300 with a 160. This is with a 26" barrel.

Triple BB,

Dont forget that you were reloading for the 300 Ultra and the 7mm Ultra having a smaller bore, 26" for 26" he will not get velocities to equal the 300 even if the bullets weigh the same. If he increases the barrel in length he will then get blistering speeds, even w/160 grain bullet.

I didn't think he mentioned which caliber Ultra Mag he was talking about.

Re: Lazzeroni velocity?

Just a guess on my part but I do not think a 1" twist change would have as much influence on pressure/velocity as the myriad other variables between different barrels/bores/chambers/brass etc. ad nauseum.

I'm sure it has an influence but don't have any idea at what point it would become quantifiable. The amount of energy expended to "spin" a bullet is very small.
