The 140 is heavier for caliber in the 6.5 than the 140 is for the 7mm. Not a fair comparison. Better BC on the 6.5 will keep it flatter beyond 500 yards. Do the same test with a 168 vld in the 7mm and 140 vld in the 6.5. The 168 will always be superior to the 140. The 7mm will always be the better choice in performance for both drop and wind. Hard to beat a 6.5 for hunting in any cartridge. The 7mm is a bit better choice in certain situations but not a great many. The heavy 7s will be where the gain will occur for larger heavier game animals and where wind is a big factor. Hard to go wrong with a 6.5 or 7 in a short mag or non mag cartridge. I prefer the 7 wsm of all short mags.
284 vs SAUM

If you run a 168 Berger @3150 you're still below and outside a 130 JLK @3250 at the 1000yd line. The 147 ELD-M @3150 shows up 150fps faster than the 3150 168 @1k in addition to less drop and drift. The 180 hybrid would have to start 3200+ to catch the 6.5 SAUM with 147s or 130s. The 7mms are great, but to say the 7mms will always be superior, that's not accurate. Keep in mind these are low pressure, mag length loads, run double base at 65k psi and see how much the 6.5 SAUM pulls ahead. Not trying to argue here, but the 6.5 SAUM packs as much punch into 2.930 as you're going to get.
I have to agree. I am a big fan of the 6.5s and today especially with the newest highest BC bullets, this is true. Guess I'm only stating as a hunting outfit, the 7 mm is probably going to be a better pick for game that requires the larger bullet. The post was 284 vs 7saum that he uses for hunting and also accuracy at the range. I've said since waiting for the 147 eld to arrive that it's going to be a bullet for the largest 30s and 7mms to reckon with when used on the 1000 yard line. That said, all bullets have limitations. I have a 6.5-284, 284 and 7mag. The 284 and 7mag will always be the best choice for a larger game hunt with 180s than any 6.5 in the bullets offered for that caliber. For long range accuracy however, I think many of the larger case capacity 6.5s can equal and exceed the 7mms in that area. I guess it was more of a general statement for a cartridge for both hunting and long range target work. I think I choose my 6.5-284 or 260 more often than I do my 7mm guns for most hunting I do on deer. These facts change regularly due to so many fantastic bullets being introduced recently. When I built my first 284, it was a slam dunk to go to the 7mm for 1000 yard shooting over the 6.5. It became necessary for more hits on paper or game in high winds to have a heavier bullet. Today with the higher BC bullets in the 6.5, it's making it easy to stay with that caliber for all uses.
I have a 284 SA and I used it and 162 Amax to take my elk here in Wyoming this year. I just bought a LA for another 284 to run the 175 or 180 bullets as I think this will give me a little more performance for elk, but I wouldn't shy away from the 162 or even the 160 accubond on elk.
I built the short action because I wanted to run strictly the 160-168s. At 3000 fps and mag length (2.950 ) they will be more than sufficient for most big game. My long action 284 does shoot the 180-195s and if you think your under gunned with the 162/168 bullets for elk, then the 180s will work. I think the 162s will get it done easily out to whatever range you need to use the gun at. Attached is a chart showing what you can expect with the 162 Amax in a short action. That's at 1000' elevation. Elk hunt usually happen at around 4500 and up, increasing those speeds and decreasing drop.

Oh I don't think I am undergunned by any means with the 162's. This is the first elk I've shot with a rifle. All my others are with a bow. I shot mine at 9500'. My range here in Cheyenne is 6000' so its been nice.
How did you like the Amax performance and what range was the shot made at ?
224 yards. Bull went 50 yards. Entry but no exit. I didn't hit shoulder bone either. So I may have been a little to close for the Amax. The eldx may have behaved better
Yep more than likely
How do you like your 260 and 6.5x284? With all of this talk it makes me want to go with a 284 on my rebarrel project instead of a 6.5 cal.
Love them both. Recoil is light and they shoot fantastic. Just not quite as good in wind as the 284 heavies. Every bit as accurate and better at times. They can do anything the 284 can do except on windy days, there just a bit more squirrely. I built them some years ago however and now I see some pretty wicked 6.5 bullets out with outstanding coefficient numbers. Thinking my 6.5-284 will now possibly rival the 284. Looking forward to putting them to the test.
284winner, what do you think contributes sometimes to better accuracy in your 260's & 6.5x284's over the str 284, are they inherently more accurate or does less recoil put it our minds that it's more pleasent to shoot!
Can't say. Mine shoot for sure. Not saying my other guns don't. Not sure that it's inherent or not. I have 308s and 243s that shoot as well but out to 600. My LR 284 shoots as well most of the time as well. Recoil, inherent accuracy, stock design or shooter preference and overall comfort ? Not really sure I can answer that. We all set out for the ultimate accuracy of our rifles. I'm just glad that the accuracy I acheive, makes me happy overall. I'm sure it's not even close to what many guys would call accurate. Works for me and for what I do.
