I killed my 800 lb cow moose with a new Browning X-Bolt in .270 Winchester with 150 grain Winchester Power Point bullets.

Ed’s Moose taken Sept. 19, 2023

The rifle was zeroed at 100 yards. The .270 is great on deer, good on elk and can easily kill moose broadside but has some distance and energy limitations. On the flip-side, the advantage of the .270 is lighter recoil and improved accuracy.

Distances are somewhat restrictive. Muzzle velocity form this bullet is 2850 fps, thus I calculated drop and energy on-line with JBM Ballistic Trajectory for this bullet before the hunt to determine my limits.

The JBM Ballistic calculation below provides data for the hunter to use in determining max range, energy and bullet drop.

Accordingly, I followed my own rules for energy.limits. I would not pull the trigger when terminal energy is under 1500 ft-lbs. In my case, under 1500 ft-lbs is at 300 yards. Luck would be in my favor with my guides laser distance at 240 yards. Energy was over 1600 ft-lbs and a broadside shot. I held 6 to 8 high from my BOG tripod rest and fired from a sitting position. A second later you could hear the bullet hit with a hollow drum-like thunk.

The moose never moved but you could see she was hit.

My guide says, “fire another shot.”  I aimed a bit higher near the spine and fired. She fell like she was pole axed. 

Examination of the wound sites showed 2 hits, one high and one low on the chest. The high hit was a few inches below the spine, my second shot. My first shot hit low in the chest. The lungs were a wreck, blood had filled the chest cavity. My guide Matt pulled heart and lungs from the chest along with the lower gut. I wanted to examine the heart. As you can see below the first bullet gashed the gallon-sized heart. This was not luck, it was understanding bullet drop and a good tripod rest. Well, maybe a little luck! We did not see any exit wounds but did not look for the bullets as we had work to do. 

For those readers interested in the Ballistics data below is the JBM Data for Drop and Energy. You can see velocity at 250 yards is 2196 thus the bullet will mushroom. Drop is 8 inches and delivered energy is 1606 ft-lbs and did great damage without an exit wound. 

Good Hunting!
