Re: ballistics of 7mm-08 & 6.5x284

Can you get a 162 to fly 3000 fps out of a 7-08? Also, can this be done in a 24" barrel? Man if so, I might have to consider a selling my 6.5-284 and set up a 7-08 with 168 berger vlds. I thought 3000 fps is 7mm mag levels.

Try doing the math at 2750'sec levels. 162 Amax = higher bc despite less velocity

Compare 162 at 2750 versus the 140 at 2950. You will see how close they are. There
Are exceptions to every rule such as pushing the 6.5 to 3100'sec but you can apply the same to the 708. Running R17 you can reach 2900.

Don't get me wrong, I own a 6.5x284 and love it.

No, a 284 win (ballistic twin of the 280 rem) will only push a 162 grain bullet at around 2850-2900 fps from a 26" barrel. I have a 7mm-08 and a 6.5x284, i am building a 284 win to replace the 7mm-08 if that tells you anything.

If i had to choose between 7mm-08 and 6.5x284, 6.5x284 HANDS DOWN. I feel to take it long range with a 7mm, anything less than a 7mm-08 A.I. is wasting your time. The 6.5x284 will whoop a 7mm-08 in the wind, dont believe me? How many 1k f-class open shooters are shooting the 7mm-08? With the 160 grain 6.5 matrix VLD with its .720 G1 BC...... no comparison.

And that is anything but apples to apples.

I dont think so, he wants to know how the ballistics of the 7mm-08 compare to the ballistics of the 6.5x284. With the 160 grain matrix at 2800 fps vs the 162 grain amax, the 6.5x284 wins hands down. Now lets say 168 grain berger from the 7mm-08 at 2700 fps vs the 160 matrix from the 6.5x284, again, the 6.5x284 wins with very similar recoil. IMO the 6.5x284 is a far better round as long as you dont plan on shooting a dog town.

Re: ballistics of 7mm-08 & 6.5x284

The 160 matrix is as heavy a bullet you can get for a 6.5 versus the 162 Amax which is not the heaviest for that caliber. Where do we draw this line. 160 6.5 versus 190 7mm? The results will always be comparable using apples to
Apples. There are always trade offs however. This one has a few inches more or less windage, that one has better or worse barrel life, recoil, size of hole, energy and so on......neither are superior to each other in every category. Some yes but not all. When it comes to ballistics, 'hands down' is a very over used statement. Neither caliber in this case beats the other 'hands down'. I doubt the original poster in the context of the conversation will be looking to matrix bullets but most likely fir the wife and kid will be using more standard bullets/loads. Amax to amax (very standard) these two
Are closer than most would care to take note of.

I'll throw the 243AI out there. less recoil and equal or better ballistics with the heavies. It will anchor a buck with authority yet is relatively inexpensive to shoot, and can shoot factory ammo if needed. I like that round and will build one for my wife eventually. Get a 1:7 twist tube to shoot the moderate to heavies and fling some lead.
