6mm-06 build

New to the long range game. I want to build a 6mm-06. I have a few questions regarding the caliber. First should i use a long or short action? What twist should i get? (Will be reloading VLD 105 and 105 amax) Where can i get reloading data? what barrel length should i get?

I leaning towards a sporter barrel due to i will be using it for hunting deer/coyote/varmints. So weight will be on the lighter side. I'm also leaning toward a HART barrel due to the fact that they are located 30 min from where i live.

Any and all information is welcome. I open to suggestions/ideas.

Thanks

I don't own one. It's a good bit overbore for my liking although I did own a 240Wby which was a barrel burner. So, I may not be the best to comment.

You'll want a long action unless you want to run it as a single shot.

You need an 8 twist for the 105's and possibly a 7.5 twist if you wanted to try the 115 DTACs.

The large case capacity will benefit from longer barrels 28-30". But, you could probably do fine with as little as 25" for a hunting rig.

Search the reloading forum here on LRH and/or post a request for load data. Always be wary of data from unknown sources. The powder and bullet Mfgs have are insured and will provide reliable starting loads.

Sporter weight will be fine for a hunting rifle. But, it'll heat up fast and stay hot. It may also be a little my phinicky to tune. You might want to consider going up a size or two and get it fluted by the mfg. Hart has a great reputation. They should be able to help you calculate the finished weight of the barrel.

Good luck!

Re: 6mm-06 build

lol....just did some reading on a 6MM AI...i'm liking this a little better i think.....let me re title this thread:

6MM...

If you had one 6MM caliber you could choose and barrel life and all that crap wasn't a concern what 6MM based caliber would you choose. I don't want to hear the same old same old i have read in every forum when it comes to HOT 6MM rigs "Well why don't you get a 260 it's cheaper, don't have to fire form, won't burn out the barrel..." i hope we get the point. I want those people that love the 6MM to give me 6MM facts to build a real speed demon even if it does burn up the barrel in 500 rounds or a weekend of shooting.

have fun!

Re: 6mm-06 build

I have used several of the 6mm rounds from the 6mm Mach4 on down. The 6/06 and 6MM AI along with the 6mm-.284 and the .240 Weatherby are all in the same ballpark. I was able to better the Weatherby ballistics with the 6mm/06 by about 100 fps. with 100 grain bullets. To be fair my current hot 6 project (6mm-.284) only has a 17" barrel so the velocities are not what they could be with a longer tube. All of the ones I have used were very accurate and most were easy to load for.

If I had to choose one it would be the 6mm/06 in a long action or the 6mm-.284 in a short action.

Got to love the 6mm crowd! I have or have had the .243, .243 AI, 6mmAI & the 6-284. My baby is a long action 6-284 running the 107smk, I love this combo, very flat shooting, no recoil (albeit the rifle is 14.lbs) & as stated in Sierra's 5th edition manual, has set a world 1000yd benchrest record (which no longer stands). The 6mmAI is my varmint rig, 3 shot goups usually hover in the .3-.5 range @ 100, slightly heavier than sporter contour which I would recommend to you. The 6mmAI is a 1-12 twist so I cannot tell you if it can keep up with the 6.-284 or not.

The one thing you should consider is this: with the 243AI & 6-284 you can use Lapua brass, which doesn't mean much to some & means everything to others.

For me, I'd build another 6-284 before any of the other 6mm's i've had/ do have.

With the '06 case or the 6mmAI case you will have to use the long action if you want a repeater. I have 243AI 1-9 twist and crank out the 105 A-max thru a 27" varmint sporter contour. It shot the 95VLD's into one hole but I had to slow them down to get there so I went to the 105's and never looked back. Better than 95vld velocity and groups are only .080 bigger. I'm using N-165 powder. Longest kill antelope buck 434 yards was trying for 800 yards but they were already shot at for 2 weeks and were just too closely grouped for 20+ Wy wind for that distance. Did the stalk thru a drainage ditch and 400+ was close enough. Took him with one shot DRT. As stated previously Lapua brass is nice and can take a beating. Watch your brass necks on these hot 6mm's. Annealing is a good thing. Lapua not as much 'maintenance'.

Re: 6mm-06 build

Does 6-06 brass need to be fire formed? or do you just rung 25-06 brass through a FL 6-06 die
