6mm-284vs 6mmAI

Anyone have any pros and cons on either of these two rounds? I wanted to do one of these two for deer fun gun.

The 6mm AI doesn't gain much over the 6mm. There is a list of the % improvement over the parent cartridge for all cartridges that Ackley improved. Check it out. I have a list but don't know how to attach it here. I'll bet it is on the net. Therefore I would go with the 6x284.

Re: 6mm-284vs 6mmAI

I would think the 6mmAI will have a longer barrel life for two reasons: less powder longer neck.

While you have to neck down either 284 win or 6.5-284 (my choice) to get a 6mm-284 you have to fireform the 6mmAI.

A more pertinent question might be which brass is readily available? Same for dies.

To my knowledge only Rem and Win make 6mm Rem brass. You could buy RWS or Norma 7 x 57 brass.

The 6mm-284 can use win, norma or Lapua brass.

I shoot a 6mm-284, 12 twist. All I can say is Wow is that thing flat shooting with very minimal recoil! I zero at 100 yards and it prints +2.5" at 200 yards then zeros again at 300 yards. I reshot this at the ranges just because I was amazed at the results.

I would build a 6mm-284, easy cases to obtain, no fire forming, simple necking down and accurate.

Re: 6mm-284vs 6mmAI

I might as well admit I have THREE 6mm-284s. I began with a monster 20 lb heavy barreled rig twisted to shoot 115s. Ended up with 105 hybrids at 3445 fps.

I owned the reamer and an old lathe. Decided to chamber and fit a 20" 243 rem takeoff to a Ruger M77, my first barrel job. That rifle shoots the 87 hornady at 3375 fps

Then rechambered a 24" 243 on a SA Rem 700. It shoots the 95 gr Berger classic at 3350 fps.

Those sporters are flat shooting: Ruger with 87 gr 1" at 100 4.6 low at 300
Win with 95 .9 at 100 4.7 low at 300

Must admit I love this chambering....

Re: 6mm-284vs 6mmAI

I went to my smith with the same question, He talked me into a 6 AI even though the 6.5 284 brass is better, I am glad he changed my mind! I run 52 gr. rel 19 with the 87gr. hor. honest 3660 no preasure at all. Even though I turn the necks to make them the same I can shoot factory ammo to get cases neck is .270 I use win. brass I do have a 28 inch barrel, also a brake so I can see my own hits

Forgot to mention, Richard Franklin, had a good write up about them on the 6BR fourm that is where I got my starting loads from. He was on the guns of the week!
