6.5x284 norma

I'm in the process of starting a new 6.5x284 norma build, and I can't decide between the 130 Berger or the 140 Berger. This rifle is going to be my go to long range deer and antelope gun. For those of you that have experience with long range shots on deer with the 6.5x284,using either of these bullets,your advise would be greatly appreciated!

Well, before moving forward even with bullet choice, what barrel length and contour are you considering? I ask because I now realize that I should have gone with a longer barrel. Don't get me wrong because I love my little light-weight 6.5-284. It has a 24" Bartlein barrel on it with a gain twist ending at 8T at the muzzle. But when trying the various popular powders among the experienced guys, such as Retumbo and H1000, I will tell you my velocities at max loads were very disappointing. I was only rocking in the high 2600s to very low 2700s and that included H4831SC also. Those are all with the 140 Berger VLD, Lapua brass, 210M primers.

I will use this rifle for shorter range hunts here on the east end of the country but if I had to do it all over again, I'd go with a 26-27" bbl, a little heavier, like a 4.5 contour with the OD being around .650-.675 from a straight-line taper starting at .850, 4-6" from the recoil lug and I'd flute it.

Re: 6.5x284 norma

For what you are wanting to do I recommend the 140 VLD, either Berger, JLK, or Hornady. I'm going to be in South Carolina the first week of November and my primary test loads for that week are using a 130 Nosler Accubond. I'm hoping to get satisfactory accuracy/precision with Re19 as many references show it provides top velocities, and it is more temp stable than Re22.

My brother said a very long shot on his club is 300 yards so I'm hoping for 3" groups at that distance or less and I will call it a day, stuff about 30-40 brass that way and go hunting.

I'm still working on the 140 VLD too though but may stop unless I get around 2900fps with my current barrel along with acceptable accuracy. I'm seriously considering sending the barreled action to Bartlein and having them rebarrel with the contour I described earlier. I'd like to go back and revisit H1000 and Retumbo as well as Magnum powders but I now know that is a waste of time with my 24" tube.

Derek, thanks for the reply buddy! I'm putting a #4 brux finished at 26in with a 8 twist. This is going to be a carry gun to pound the mountains in the 9-10 pound range.

If your barrel has not been started, consider a #4.5 but flute it. Prolly won't make much difference but who knows.

Re: 6.5x284 norma

I guess I think the heaviest bullet with highest BC is the best route. I have shot 160 Matrix bullets at LR they hit harder the 140 which is getting there flatter and faster. I personally don't even consider a 130.

I have 24" barrel and would go 26 personally. I am the opposite of Derek. With retumbo I get 2900 to 3000 easily. What I discovered today has me baffled and will be starting a new thread for some education on the subject. But I shot a some rounds at 3000 fps after dropping the powder level to 56 grains. My go to load used to be 57.5 and I was shooting 2970. Go figure.

I started out in the mid 50s grain if I recall and I never saw those kinds of speeds. This was the same day I was cranking 3050+ in my 270, 24" Krieger with 150 VLDs and H4831SC and my 7RM with 168 VLDs with 73.0 gr Retumbo going over 3000fps.

I don't think I saw over 2720 with Retumbo or H1000 and the berger 140. So, I'm guessing I just have a slow Bartlein barrel? Makes me very curious what would happen with a barrel change out to a Krieger or Hart, same contour, also 24" and same reamer used by same smith.
