Like Harperc said it tends to get a tad drafty this way. Especially when I head to the western part of the state. I would think that the heaver 338 would buck the wind better. On the other hand. The 338 uses 250,and 300gr pills that's a lot of bullet hitting good meat if I make a bad wind call, cause im not perfect. I don't know if the 168 I planned on putting thru the 7 would make such a mess.
Mudrunner. What ammo did you run thru your 338, factory or hand loads, did you try diffrent bullets all the usuall stuff to develop a load
I would imagine the .338 would make a substantial mess, then again, so will anything if the shot hits the wrong place.
There's people who drop moose inside of 500 yards with .25-06's with 1 shot. Shot placement is EVERYTHING. Brute power is important with large game, but it is not all there is to a successful hunt. Ask the member on here (can't ever remember his name) who dropped a monster moose with 1 shot @ 9xx yards with a plain ole' 7mm RemMag.
As for my .338 failure...
One box was handloads using 210gr Swift Scirocco's, and the other was a box of Barnes Vortex 210 TTSX's. It didn't like either of those, so I snatched the barrel and sold it to someone else. Then I turned that rifle into a 7mm RM for deer season this past year. Which is now a heavy barreled .300 Ackley Mag in a HS Precision Sendero stock.
If you want a 1500 yard monster shoot a .300 Ackley Mag with a Berger 210 VLD, or even a 215 Hybrid.
It's basically an improved, fattened, 40* shouldered .300 Weatherby. It hits hard.
Also, my gunsmith has been smithing for 25+ years (machining for much longer than that), and he builds benchrest rifles that will put 5 in the SAME hole @ 200 yards. I've seen his trophies and his targets. I've also seen how he makes my rifles shoot with a worked factory barrel on them.
He won't own a .338 Lapua. He built simself and a couple clients one, using custom actions, Krieger barrls, and McMillan stocks. All 3 of them couldn't get any of the rifles to group better than 5/8" @ 100 yards. He said average was barely under 1" groups on a no-wind day with perfect conditions using Lapua brass, Lapua bullets, and whatever model Vihtavuori powder.
He'll build you one...But he won't guarantee accuracy.
That's not why I don't like them, I disliked them long before I used the gunsmith. But seeing how he can make my factory barreled guns shoot 1/8 and 1/4 MOA groups @ 100 yards, I take his word for it.
