Leverevolution tragectory
« on: September 08, 2009, 05:03:16 AM »
Does anyone have a trajectory chart for the Hornady leverevolution 30/30 ammo? I see what it can do at 100,200, and 300 yards off the hornady website. I am wondering what it looks like in-between those ranges. Especially at 50 and 150 yards. Its twice the price here than what i usually buy for my 336, so I want to make sure i know what I am buying befroe making the plunge. Thanks!

Thanks. So If I wanted it a inch high at 100yds, it would be -.49 at 50yds? Thanks again!

My range time comes up with a little different results. Could it be the short(18") barrel?

Have you checked your gun across the chronograph to see if your velocities match the ones is the charts above?

Every gun is different...that's why we love them so much  :D

When they come for your guns, give them the ammo first.

The Hornady velocity is from the 24" barreled XLR, I think all of their LE data is from a 24" barrel.
