My post on another thread:

Whether a 7/08 is 'equal' of a larger capacity 270...well, as I have mentioned in posts before, I have clocked 21" bbls, TWO different rifles, factory unaltered chambers, at 2900-2960 with 140s. 120s shot 3050-3100 in the same guns...imagine those 10 grains less wt. from a 130/270 bullet is not a huge difference in how a bullet flys...or kills, many love the ballistic tips or the Barnes in 120s out of the 7/08. In a short tube i.e. 18.5" model 7, it's a loud gun that loses a good bit of potential speed no doubt as many rounds will in those short tubes.

It may not be equal, but I am not sure how much faster 140s go in a 270, esp. in a 21" bbl. I am sure my handloaded 7/08s were faster or equal some 270 factory loads, so for ME, the 708 is so close to the 270, for me to pick it over the 270. Owned a few 270s in the past, all shot well, killed well, and yes Cypress I agree, animals never know the fps, not mv or impact. If placed correctly and bullet penetrates vitals with some expansion properties, death usually results.

BTW, I just ran some numbers: http://www.biggameinfo.com/index.aspx?page=%2fbalcalc.ascx

Here is what I found:

270/130 accubonds, .435 BC/3100 mv, 200 yd zero, 500 yd drop 36.9", wind 18.6" at 10mph. Energy @500yds 1267 lbs. SD .242

7mm/140 accubond .485 BC/2950 mv, 200 yd zero, 500 yd drop 39.5", wind 17.6"/10mph, energy 1329 lbs. SD .248

SO, there you have it, a 7/08 drops 2.6" more at 500 yds vs. the 270 load, but has 1" advantage in a 10mph, also better by 62lbs energy....

At 500 yds, I can't hold that good, much less judge range, but if one had an LRF, and a scope to click, one could shoot deer with either about as far as you might expect to need/want, and kill with either, if the bullet lands well. ON larger game, I am confident a stouter bullet will get the job done, many stopping at 140 partition or barnes, but 150-160s are there, inc. the partitions, etc.

I don't know what 'practical' advantages a 270 has...ballistically than a 7/08. Not knocking the fine 270 and what is has and will continue to do, but the 7/08 is no slouch in my opinion and experience with both rounds. I doubt a few fps and .007 of an inch will ever be distinguished by most shooters or animals taken with either....marksmanship and bullet construction are much more important.
