Fotis that's an interesting table to read through.

If that's what a 7mm Rem Mag looks like at 65,000 psi I suspect I've never loaded that hot. Anytime I saw over 3100 fps with a 160 gr from the cartridge I'd stop and throttle back a bit.

But it does show how much better some of these modern slow burners can be in the cartridge.Can't help but wonder how they'd hold up in real life. That first load with V N570 grabs my eye.....77 gr for 3253 fps at 65,000 psi, That's a lot of velocity from the cartridge with a 160. Ditto for the RL33 load for 3238....Good to remember this is for a 26" barrel.

Interesting.

Anyone know how does QL arrive at its figures anyway?




The 280 Remington is overbore.

The 7 Rem Mag is over bore.
