We shot quite a bit this evening getting ready for caribou and again was very impressed with the little 300 WSM. I have been working with this one in a 25.5" barrel for about a year now and it just never fails to amaze me as I learn more about it and the powders that turn it on. I hit on a load this evening that was hitting one hole groups at 100 yards which I have come to expect with this rifle and is common. What amazes me is the 150 grain bullets were clocking 3455 fps with 5 fps extreme spread. Now I have this little gun clearly into 300 win mag performance with less powder, kick and noise. The E-Tips have a .469 BC which makes this little round a great mountain backpack deer rifle. The ballistics look very good on it. It weighs 7.2 pounds scoped out and ready to hunt. I like It for backpacking! Also amazed with the 300 ultramag with factory ammo. I always wondered what the factory stuff would do. Remington 180 grain nosler partitions clocked 3346 fps with 12 fps extreme spread. At 400 yards they hit a 1.8" group. Why am I reloading this thing? 257 wby performed as usual, outstanding. .92" group at 400 yards with 100 grain TSX at 3780 fps. Caribou be aware. 338-378 with 200 grain nosler clocking 3615 fps with awesome groups at 400 yards. Amazing what it does to gallon jugs full of water even at 400 yards. My son had a blast with it and the 257 wby popping jugs. Now time to pop some Bou!
