It’s on the shelf in both Cabela’s and sportsman’s locally for me. It was one of very few that I always saw during the worst of the shortage. The 284 case isn’t going anywhere

Thanks! I picked some up. The shipping was a little excessive but better than not having brass.

Following along here. I’ve got Lapua 6.5-284 brass and have been looking hard at 25-284.

However, running the numbers, it looks like the 6mm-284 with a 108gr Berger is a lot better fit in a short action AICS mag than the 25-284 with 133gr Bergers at reasonable seating depths. I think I’ll throat to load 108s in a binderless magazine, which should leave 115gr options on the table for something like a 3” Wyatt’s box if a better heavy for caliber bullet comes out down the road (120 ELDM anyone?)

I’ve always had a boomerish fear of 243 caliber deer cartridges from growing up, but reading on here and some of the podcasts on 6CM/6UM has changed my mind. I’m excited to see your results with the -284 case. For the price of Lapua -284 brass (and not having to fireform) and the low cost and high availability of good .243 bullets, this seems like a winning combo.

Now what to do with these .25 bullets? 25-7PRC?

Long story short I'm in love with a gun for the 1st time in my life with my 25-284 build! I've been using it religiously for the last year and it's done everything and more that I've asked of it.

My fellow hunters are starting to see the light and enjoying the benefits of small calibers going fast, and I just spun on another 25-284 barrel for a good buddy.

My father wants to build a lightweight, fast gun with low recoil. The build will be off of a tikka standard bolt face action. I'm leaning heavily on a 6-284 for him. For those that have dabbled with it, is it as simple as the 25, where you just full length size 6.5-284 brass? If so I think this is the ticket.

I'm guessing 3100fps with 108s abd retumbo or n570 would be attainable out of an 18" barrel suppressed?

Side note. He already has the donor gun so no 6UM or other mag bolt face cartridges.

If you've built one or have any experience with the cartridge tell me everything!

I LIKE IT!!! Holy smokes sounds like a fun deer/speed goat cartridge.
As for the .25cal, one of my favorites is a .257WBY with a fast twist barrel for heavies…..Also, fun for deep and antelope.

You’re spot on with the mag limitation of the 25-284.

I’ll not chime in too much with the 25 cal stuff…I’m pretty stuck on my boring 25 creedmoor which does everything I need and more from a 26” barrel.

 

[texag10]

I have a Tikka I've rebarreled to 6.5-284. I've loved the performance on game, but wouldn't mind a 6mm faster than the Creedmoor case to reduce recoil from my 6.5 and still give good velocity in a much shorter (18-20") barrel.

What would I need to reload 6-284? I have a Hornady match 2 die set with a neck/shoulder sizing and decapping die that uses a bushing, and a seater die.

If you have a 6.5-284 bushing die set all you'll need is a different size bushing and you're good to go.

Sorry to bring up an old thread. Does anyone have some MV data on 6-284 with 108 with 20”ish barrel.

No, I'm going a different route due to current brass availability. Should have data in a couple months on 2 different barrel length 6-6.5 prc's. One is 16" and the other is 19".

That’s kinda what I’ve been leaning towards. I have a 6.5-284 with a 22” barrel, I’ve never really got the speed I wanted out of it.

If i remember I'll post up the results

I kicked the 6-284 idea around but have since gotten a mag bolt. I thought a 6-6.5 prc sounded good but if I’m already necking down brass y not go straight to a 6um

I'm torn between the 6prc or the 6um for my tikka haven’t decided yet.

 

[Miflatlander91]

I think if u could get your hands on enough adg brass I’d go um that’s my plan if brass turns out to be impossible to get then I don’t see giving up much with the prc

I’m also curious to see how big the difference is between the 6um 30° vs the 6um 40°.

 

[Brandon.miller.4]

For me, 6 prc was just too easy, no fireforming, endless brass supply.
