6.5 x 284 build

[TackDriv3r]

I decided to rebuild my existing BR 6.5 x 284 Remington 700 and its a short action with a tight .286 neck with a single feed to a new build as a repeater. After a brief discussion with 2 gunsmiths that the short action may or may not give clearance issues if used as a repeater rifle while ejecting a loaded round and magazine feed issues. I decided to scrap this rifle build and start a new build from scratch. Rifle will be used for bench shooting and hunting.

What do you guys think?
I have a 6.5. Creedmoor capable of 2800 fps with 140 grain bullets ( haven't gone that fast though )
I just need a little faster 6.5 and already have all the existing dies / components for a 6.5 x 284 since I have an existing single feed 6.5 x 284

One question bugs me, is the 7.5 twist too fast and should I use the 8 twist? I just can't pick which one to use and I hear the higher RPM tear bullets apart like the 7 twist. Is that true? I just don't want to make the wrong choices on the twist on this build.

Berger website says the 153 and 156 grain offerings can be used in 1:8 twist and faster, will 7.5 twist help a little better to aid stabilization?

GAP says the 7.5 twist is their standard twist for the 6.5

You made the ideal choice in the 7.5T. With today's longer/ heavier low drag 6.5 bullets, the 7.5 will stabilize them perfectly. My 8 twist works fine but with the heaviest 6.5 bullets, the 7.5 is a better option. While the SA would have worked, you'd have been limited to lighter bullets or less case capacity making the 6.5 CM probably a better option. Also with the RL26 option, you'll get better velocities without sacrificing barrel life. H4831 and H4350 were my go too powders but now the RL23/RL26 are two more great options. Many other powder options available but those 4 are my favs. Good luck with the build.

I think your going to love it. I have those same marble colors on a HTG and it’s my favorite, it may have been 60/30/10. What’s the barrel contour?

I put a 7.5 twist on my 6.5x284 recently and it really stabilized the 142 SMK at 600yds. Used that twist this time with the idea of the 153.5 Bergers...

Barrel contour is #7

Question if i may, will 7.5 twist be fine to use 130 grain bullets as well?

"Color for stock : Marble : 70% olive, 20% black and 10% light grey"

That's pretty close to what the colors on the MCM A5 to my 338 Lap Imp are.

I have a fluted #7 on my 6-284 finished at 26 with a NF NXS and it shoots better than I can but she's definitely got some heft to her so I'll bet your's will weigh in at around 13-13+lbs when it's all done.

Having a 6 and 6.5-284 I'm kind of partial to all things 284 but I'm sure you'll be very happy with yours and it sounds like you've got an extremely nice build going together.

Yes. It'll shoot pretty much all the 6.5 bullet weights.

That is a beauty. Yes, my other 2 GAP rifles weigh around that much. Thank you buddy.

Thanks for the heads up. Thanks all fellas for the advise.
