Home Forums Hunting & Shooting Custom Rifles & Wildcats what 6mm wildcat?

If your not looking for speed a 6MM BRX is a very good round and wins lots of F class shoots.

22 Creed, great brass, no fire forming

I have been shooting the 22/250 AI for many years, love the case, super accuracy.

If you are a light bullet man for shortish range coyote hunting, then a 6 Creed, very short freebore, 55g Nosler would be way over 4000 fps with bug hole accuracy.

If you want to do it all with one bullet, the 105g Berger Hunting vld, the 6 XC, 6x47 lapua, are idiot proof in tuning a super accurate, fast load, tiny, tiny groups that carry the freight way out there. It is a real shame they quit making the 105g A max.

In 6mm I have to say I am really happy with my chunk, Criterion Remage, 75 dollar B&C plywood varmint stock, Timney trigger, SWFA 10X SS..........6x47L

The photo was after I screwed it together with ~28" barrel, it's now 20" and threaded.

I was planning to get completely out of the Lapua after selling the evil twins but no way am I jacking with this one, it's accurate, consistent and fun to shoot!

Single pass with 6.5x47 through Forstner 6x47L dies.

Load is 105 Amax over H4350 and CCI BR primers, 10-shot groups at 100 below.

RDW nice choice and I really like the bench box. Did you make it?

I am still wringing out a 6AI but it is primarily for hunting and 95-115 grain bullets. For targets shooting anything in the 6BR-6XC range would be good. A 6 Creedmoor or 6x47L would probably be my picks.

Thanks, aalf steered me away from the Dasher to the Lapua.

My wonderful and always thoughtful sister gave me the shooters chest for Xmas last year, H. Gerstner & Sons

RDW, that is a sweet rifle and a nice shooter. Cool stuff!

Yeah I have a straight-up 6-250 (not an Int’l or XC) I bought here and absolutely love it.

If I’d have built it myself I’d have twisted it faster than the 10” Sako it has.

I’ve killed a bunch of stuff with this rifle, and my young boys and other new shooters have learned to shoot with it.

The muzzle blast is significantly less than the .243, and this is a very easy wildcat... I just run .22-250 cases through a 6mm neck sizer & VIOLA!

+1

I got much the same with a Shilen 14T, zero freebore reamer, 70g Noslers at 4150 and 55's Noslers at 4400.

I had another 10T chambered with the same reamer, 70's accuracy node was at 3980 fps.

both barrels were 26" long.

I used Win 760 in both guns and primers made a big difference in the group size and SD.

This size case is better in a long action or with a Rem short action that has a Wyatt's mag box. You can get longer length out of some detachable mag boxes I recently became aware of.

IN another rifle, 14T Pac Nor, I shot the 60g Sierra at 4400, rock chucks splattered on rocks like paint balls.

These kinds of speeds are hard to imagine in just how fast a bullet gets there, and how humanely it kills so fast.

In the 243 AI, with the same zero freebore configuration, The 70g Noslers in 26" barrels were in the 3800 fps area, and a tad more with WLRM primers with "Win 760.

I shot a Coyote last weekend at 423 yds with my 22-6MM AI shooting 55 gr Sierra Blitz kings. When I rocked back into the scope he was down. I said to myself damn that was fast. I don't know what rifle I like the most. I have a 22-6MM AI with a 27 inch Bartlein barrel with a 1 - 14 twist. And a 6MM AI with a 27 inch Brux barrel with a 1 - 13 1/2 twist.

The 22-6mm AI will shoot .500 groups with 50 to 65 gr all day.

The 6mm AI will shoot .500 groups with 55 to 70 all day.

I also had a 6mm BRX built with a Krieger 1 - 8 twist that will shoot the Sierra 107 gr HPBT matchking in very tiny groups. Its a lauber for sure, but is scary accurate.

6mm Creed..........

That said, a 6mm-06 A.I. with a 1:8 barrel would hurt things...........

6-284 sounds fun

I have a 240 Gibbs if that counts. Shoots 87 gr.Hornadys quite well at around 3800 fps...
I haven't shot it in several years..

The 6mm-06 is a laser but is about as overbore as you'd want in a 6mm. Barrel life being somewhat of a concern depending on how often you will pull the trigger. Your 243 Win is a good one just the way it is but if you are set on changing, you could easily go 243 AI and see some significant improvement. Starting over completely and looking for a fast twist I would opt for the 6mm Creedmoor.

You have a really nice sister too. Even on sale now I think I will have to make my own.

6mm GT (Gay Tiger) should give you everything you need.

If you decide on the 6mm-284 you can expect right around 1000 rounds and it will be finished. I only shot two or three shots at a time and cooled it with CO2. Got some fantastic accuracy with a heavy target platform using a Bartlein 5R 1in 7.5 twist with necked down 6.5-284 lapua brass and 105 Bergers. I switched to a 6 BR in that heavy platform which will give me slightly better accuracy and last a LONG time.

IMO the 6mm-284 works best in a sporter rifle. I figured out how to do it on the cheap. I still have the reamer and now rechamber Rem 243 takeoffs. The twist won't work with the heavy target bullets but a 55 gr Nosler BT will absolutely vaporize a small rodent. When the barrel is cooked no biggie I chuck up another takeoff in my lathe and do it again.

FYI that rem barrel is 23 3/4" long (removed bolt recess for Ruger action) It also shoots a 95 gr Berger classic hunter at 3465 fps very accurately with RL-17 too.

I shoot 'em all and then some.

Pass the 22 Speedmire with 88's at 3250fps.

Hint.................

I’m still sweet on my 6 ai and 80 grain ballistic tip ping pong balls....

The less one "knows" or "does",the "better" everything is. Congratulations?!?

Pardon my shooting it all and then some.

Oooopsie!



Bless your heart for TRYING.
