7mmX300 Winchester Magnum Vs 338 Lapua

[375rifleman]

I was just wondering how a 7mmX300 Winchester Magnum compares to a 338 Lapua at long range? Since a 300 Winchester Magnum is at or near the top of the TC Encore capabilities I was wondering how a 7mmX300 Winchester Magnum compares to a 338 Lapua? Are there other more suitable long range cartridges for the Encore?

264 win mag

I actually hadn't thought about the 264 Winchester Magnum. As I wanted to maximize the amount of remaining energy at extended ranges. Considering that 7mm is capable of increased bullet weights over 6.5mm bullets. Although you do make a good point. .284 VS. 264 just thinking about many purpose built 7mmX300 Winchester Magnum rifles built for long range target shooting.

Not that a 264 Winchester couldn't be built in the same way.

Yeah tc used to chamber the 264 win in factory barrels. I know mgm still chambers them . And are fairly reasonable. They actually have a pile of chambering they can do with a few weatherby chamberings

Looking at cutting edge bullets I noticed their 140gr single feed Lazer with a bc of around .670 paired with a 264 Winchester could show some promise. But I don't know how it would ballistically compare to other magnum 7mm, 30 caliber, or 338 chamberings.
