You are shooting a 7mm-08... 139 gr or 140 gr

What range will you extend to...

I have had this discussion with others, and I would think 300 yrds is reasonable. Some however have spoke of the 400 yrds range and even further...

Thoughts?

The game is deer...

I know of at least one guy around here who took his moose well beyond 300 with a 7mm -08
 
The 7mm-08 with 140gr TTSX at around 2800 fps would still be travelling close to 1800 fps at 500 yds with about a 1000 lbs of energy and 44 - 45" of drop sighted in for a 6" MPBR.

If you had the equipment and the shooter was competent I would say 500 yds would be the max after that I would say expansion would be questionable and I believe 1000 ftlbs to be about the minimum energy for deer.

Just my personal beliefs.

To each their own.


Personally I would use the 120 gr TTSX. Close to the same energy at 500 yds but over 100fps faster and only 35 - 36" of drop with a 6" MPBR.
 
Coincidentally, I am shooting a 7mm-08 with a 140 grain bullet. My max comfortable range is 300. Longer is certainly possible but I don't have a range finder and haven't practiced past 300. Both are critical to success at more than 300 yards IMO.

Do YOU have a rangfinder. Have YOU shot past 250 yds with it?

In capable hands 500 yds would be far from unreasonable.
 
I'm not very comfortable taking a shot at a game animal from more than about 300, but the round has enough energy to do the job if you and your rifle can.
 
I shot a whitetail at 310 yds with my 7mm-08 shooting 140 TSX. I'm sighted 2" high at 100, held on the shoulder and hit the heart. Works for me.
 
Just out of curiousity, why is everyone using the 140 grain TSX in the 7mm-08? Seems like overkill for a cartridge with modest velocity. Wouldn't the 140gr be more suited to the 7mm magnums, and the 120gr to the 7mm-08? If not something like the accubond etc?
 
My question is not about the cartridge's ability to put a bullet out there, but at what minimum velocity will the TSX reliably open up at, if it only hits hide and meat??

That would be the maximum range for that combination. I am not a big fan of Nosler BT's for big game hunting, but I would think they would open up more reliably at the kind of distances suggested. Even better, a partition would open at even the slowest expected velocities, yet be more reliable during point blank encounters (then a BT).

Couldn't get 120's in factory ammo. I would like to use 120's if Federal will put 'em into some cases for me. The accubonds that I tried grouped about 3.5" at 100 yds. No thanks. Maybe when I start loading, I'll give em another go. I'm using the 140 TSX cuz they grouped the best.
 
The 120gr BT is a very tough little bullet that will work great at 7mm-08 velocities.

The 140gr TSX, assuming 2820fps, like Federal advertises, will retain enough velocity for expansion (2000fps) out to about 375 yards.

For me in my 7x57 accuracy with the Barnes 140gr bullet was excellent, less than MOA at 200 yards. And damage inflicted by this bullet that is supposed to retain 95% of its weight. I have shot 2 deer with mine, a whitey buck laser'd at 280 yards DRT, and a Mule buck 1/4ing towards me the next day at less than 50 yards, went for a short trot and rolled over on his back.

Now why would I want to try another bullet? FS

I'm shooting 120 BT's in mine and my dad and brother shoot the 120 TSX in theirs. So far so good.
 
I'm not a long distance shooter... born and raised with a 30/30's..45/70's etc..

The new 7mm-08 is a shorter barrel with open sights,..even with a scope on it, I'd suspect 300 yrds , but won't know even that until I get it out and shooting...

Had rangefinder and sold it last year when I sold the CZ...
In the Market for a new one..
 
I watched a skilled hunter with a 7-08 shoot a cow elk 2 years ago with the 140 Accubond. The range was ranged at 512 yards. Two shots, two hits right through the lungs. Elk went maybe 4 steps and tipped right over. Plenty of oomph left in that little 7-08. Skills needed by the shooter much more important. FWIW, I was backing him up with my 308 Norma Mag, which, as I sight it in, is exactly 24" low at 500. He told me he was a bit lower at 500 with his 7-08, IIRC 30" Regards, Eagleye
