I am far from an expert source of info on the use of the 7mm for long range. But from what I read, the current quality of bullets available is no longer a hindrance. Then if you consider the inherent ballistic coefficient advantage of the 7mm over anything else, there should be more use of this caliber in the future.
As an example, my 7/338 Lapua should be done soon. I expect close to 3,500 fps with my 32 inch barrel and the 176 grain Cauterucio (.750 BC) match bullet. The ballistics with this combo, IMHO, beat anything else out there for an accurate, practical killing machine out well past my comfortable hunting range.
It beats all the biggest 30 cal cartridges in stats for retained energy, wind bucking and flat shooting. Clicks to 1,000 yards will be 15 MOA vs 18 for the big 30/338 Lapua with the JLK 210 (.670 BC) bullet. Wind drift (10 mph)is 37 inches vs 46. Energy is 2,000 ft-lbs vs 1,850.
Another important factor is recoil as it affects the ability to shoot well and to see the bullet's impact on game. 22 ft-lbs vs 27 (assuming an 18.5 pound rifle combo.
Len - would you give me the details of your 7/338 Lapua build ,I have owned a couple of 7 mags , have always been interested in a 7 STW , and still considering it , but like my 300 win mag - the seating depth has always bothered me , Magazine length ,I realize they say it doesn't mater but....thanks
With you trying to hit 3500 with the 7/338 LI and the 176gr, and Dave trying with his 338 SnipeTac and the 300gr, my 30/338 LI with the 210gr seems it's going the way of the 300 Savage real quick like! [img]images/icons/grin.gif[/img]
I'm looking forward to the results.
I'm still building another 30/338 LI next. [img]images/icons/tongue.gif[/img]
How's your 30/338 LI shooting? You've been too quiet about that thing, now come on, out with it. [img]images/icons/grin.gif[/img]
