6=284 Loads

[Hollister DeLong]

I just picked up an FN Mauser made for Mexico. It is in 6-284. I calibrated the twist at 1:11 and the barrel length is 23" (UNKNOWN MANUFACTURER). What is the heaviest bullet that this barrel will shoot accurately? What is a good load to start with? Of course I want the fastest, most accurate and safest load I can possibly get with the least amount of effort on my part...I want a winning lottery ticket, as well

Bullet stability will depend on weight and length of bullet, velocity and altitude. Berger has a twist rate stability calculator. With an 11 twist, you wont be able to use some of the higher BC bullets due to their weight and length.

For load info, google 6x284 load data and you should get a bunch of results. Nosler, Hodgdon, Alliant and some other sites also have online data. RL17 should be a good performer in the 6x284.

Hope that helps

The 6-284 is among my favorite cartridges. I do have to offer you some consolation on very short bbl & slow twist.

^^ here is a link to a stability calculator, this will be your friend


Depending on altitude & velocity, I would imagine the 87grn V-Max would be your best. It should stabilize (I hope) & offers a decent BC to boot.

I run a 28" 1-8" twist Kreiger with bullets over 100grains only, I can't really help with the load data part.

RL17 should be a good performer in the 6x284.

I was thinking of the 6.5x284 when I recommended RL17. It might be a little on the fast side for the 6mm version, but with lighter bullets, it might work OK. Slower powders like Retumbo and H1000 might be good candidates.

Here's a good thread to get you started. RL17 has about the same burn rate as H4350.
