The 120 BT you’ve been using is a do it all bullet in the 7-08. It’s a whitetail killing machine. And hogs and black bear.

140 AB bc is .485. Partition is .434. The same load (47.5 gr Big Game) generates slightly (30 fps or so) less velocity in the AB compared to the PT. So here’s the math, velocity only:
140 PT, .434, 2890 fps 300 yards 2280 400 yards. 2095 500 yards. 1919 600 yards. 1752
140 AB, .485, 2860 fps 300 yards. 2314 400 yards. 2147 500 yards. 1986 600 yards. 1833
81 fps at 600 yards isn’t impressive.
P Good stuff. What's the wind drift numbers for those?

No I have not shot anything with that rifle. Got it just before COVID-19 started. I did see a video on you-tube
where the 130gr speer penetrated the ballistic gel very well. It was the best round in the test. I might add
I would also look at the 120gr Barnes TTSX.

If your rifle shoots the 120’s well and you want a stouter bullet than the 120 BT, I would consider a 120 TTSX. I shoot a 7mm SAUM and have had so much success with the 120 bullets I have felt no need to go heavier. I have witnessed a 120 BT take down a bull elk with one shot. The TTSX at SAUM speeds is a death ray and will out penetrate a partition. Not knocking partitions I still use them and Barnes almost exclusively for hunting. Nothing wrong with trying heavier bullets... I have some 139 LRX I plan to experiment with just to see not because I feel I need a better bullet than the 120’s.....Good luck
YMMV
PASS IT ON!

Thanks for all the suggestions. I think I’ll stick with the 120 Ballistic Tips for deer and when I shootout my supply switch over to the partition. I’ve only shot one deer with the 120BT but was surprised to not get a pass thru on a broadside shot at roughly 200 yds. Sample size of one so I guess can’t put too much weight on it. Plus, the deer did go down quickly.

I haven't shot any 7mm bt" but I've killed a lot of deer with with the 6.5 bt 120gr. , no pass through, and no tracking all dead in sight. I have come to believe that a 120 grain bullet at 2800 or 2900 fps is all you need for deer.

Pharmseller, which was more accurate, AB's or NP's? I have a supply of both and will be trying Big Game as well.
Start young, hunt hard, and enjoy God's bounty.

P Good stuff. What's the wind drift numbers for those? No clue. That's fairly important when you're shooting over 400-600 yards.

I just hold into the wind about that much. Sure, sometimes I hit them in the ass, but sometimes I hit just where I want.

Honestly nothing I’ve ever seen kills better than a 140grNP at 7mm-08, .260rem , 6.5 CM velocities. Elk and deer. FWIW the Accubond at those velocities is extremely partition like.
