max range 6.5 284

Need a little info on terminal ballistics of the 6.5x284. What is its max killing range of this round. I seen a guy on youtube drop an elk at 900plus yds. Is this normal for this round. thanks

Well over 900 with the proper bullet and rifle pilot is a good number....

That was Jeremy from BOTW. I was surprised at the kill myself because I really didn't know much about the round. Sure killed that elk fine.

I built mine with the 140 VLD in mind and will see what it can do in 2013 hopefully. The question now is what powder will I use and whether or not I'll use a magnum primer.

Those guys started with Retumbo, 59.0 grains I think. Then they moved to H1000. If you read this site: http://www.6mmbr.com/SixFive284.html you will see that the top 2 powders are H4831SC and H4350, both of which are Extreme powders like Retumbo and H1000. So I don't know of the hunters were using the slower powders for a velocity reason or not. I personally choose accuracy and precision over velocity unless there is a ridiculous difference in velocity and not much difference in accuracy among the various powders.

A reliable source who is a bench shooter and long range hunter was testing the Ramshot powders and stated to me that Magnum was just as temp stable as the Extreme powders. I have some of that on the shelf too but do not know the velocity potential. My 6.5x284 bbl is 24".

Re: max range 6.5 284

I have not shot an elk but have taken several deer and antelope out to 1000 yards with my 6.5x284. The terminal performance on all my game shot was quite good, most dropping in their tracks. If the 6.5x284 was my only rifle, I would have no problem using it on elk. While I have no doubt it would kill an elk at 900 yards with good shot placement, I would prefer shots to be closer.

Re: max range 6.5 284

Derek,

You are right about using 59 grs of Retumbo for our 6.5x284 set ups with the 140 VLD. There were several reasons we did this. The first being the velocity. We were trying to get 3050 fps with a 26 in barrel and Retumbo was consistantly doing that for us. The second and probably the most important was the temperature stability. We tested hundreds of rounds through several different rifles and found Retumbo to be the most stable powder for minumum of 50 deg changes. Magnum tested well also but just not quite as good. As you know we run the bdc turrets so a stable velocity is what we were looking for. They switched to H1000 because the 59 grs of Retumbo was a compressed load even with a chamber throated for the vlds just into the neck of the cartridge. H1000 gave us velocities in the 3000 to 3025 fps range. I personally like the 4831SC especially in the WSM cartridges. The 6.5x284 with the 140 VLD is a great cartridge for large mule deer on down. It is a good elk cartridge out to 1000 yards just remember not to shoot them in the shoulder. Put it right behind the leg and through the vitals it will do the job every time.

I use 59 gr of Retumbo, Federal 215 Magnum Primers, Lapua brass, and 140 gr Berger Hunting VLD's. Seating depths are .075" out of the lands for both my rifles, a Savage and a Cooper. I have tried H4831sc. It produces the good accuracy, but will give velocities 80FPS lower than Retumbo. Using Retumbo, my Cooper produces 2965FPS, my Savage LRH, 3015 FPS. Both rifles consistently produce .25MOA. 3 shot groups at 200 yards.
