6 dasher sons starter target/ hunting rifle

[1611]

I got my hands on a rem 700 SA SS with a .473 bolt face repeater action. Looking to build my son his first target/hunting rifle with it. I have been looking into different cartridges for my son and keep coming back to the 6 dasher.

I haven’t left the warm waters of traditional.308 cals yet (sammi 308 win, 300 win mag and 300 PRC chambers) it would be a fun project for us to embark on. He will he shooting prone and off a bench with me out to 1k, then some groundhog hunting prone 0-500 yards. For the most part I’ll be transporting the rifle in a case for him. Just put him behind the rifle until he is older.

Looking to run it out of DMB with 105 Berger VLDs, Lapua brass. Could you guys recommend the neck and freebore I should spec to maximize the potential of this cartridge for this configuration? Also the ideal barrel length? I don’t mind turning necks if required. I will have him involved with the handloading and development.

Thanks
Dip

Just like George Washington Carver going insane trying to play a phonograph with a peanut so have many a man done so the get a Dasher to feed repeatedly and reliably 100% of the time.

Not to worry the Almighty provided me with patience. I am reading up on some of the issues with running the dasher on a factory rem 700 action. Might have to make a few minor modifications. The way I figure if I wanted something easy I’d buy a 243 and be done with it.

For the stated use, why does it have to be a repeater?

It’s a repeater action I got my hands on. I want him cycling the bolt after firing and re-acquiring the target.

The BRX, might work with less aggravation being a 30° shoulder.

A 6x47 would be a good feeding round with a little more HP. .... jim

True I have looked at this round also.

6x 47 Lapua, feeds great and shoots great.

.272" neck for a no turn with .140"-.150" freebore will work great with all the 105-110 class bullets. Personally I have gone to 7.5" or faster twist for more bullet versitility.

I put together a coyote hunting rifle with a 22” 7.75 twist barrel and run it suppressed. I didn’t want to have a goofy looking extra long looking barrel with suppressor attached and didn’t want to not be able to achieve the lower accuracy node of the Dasher. After the barrel broke in 200 rounds later I have discovered I am achieving 2950 FPS with 105 gr amaxes, 32.5 gr Varget and Fed 205 M with really good accuracy. I am tickled to death. I am achieving the same velocity as most guys that are shooting 28” barrels. Also I am using factory Remington BDL bottom metal that was originally a 22-250 with flawless cycling. Didn’t think that was possible, maybe I got lucky. Factory Remington extractor (No sako /M 16 extractor) also. Shooting 1/2 moa or better at 1000 yards.

@Yote Hunter thanks. I’m checking out the various rem 700 6 dasher builds online. Two issues I’m seeing is feeding from a mag, which it appears that there are mag inserts and upgrades available. Also ejection issues. Seems to be reporting that they run better than not. Im up for the challenge.

Another thing to think about... what about the 6XC? It's actually designed to feed from a magazine, while a Dasher comes from a single-feed cartridge with its shoulders blown forward a little.

My concern would be the additional powder capacity with less barrel life with the larger capacity 6mm creedmoor, XC, x47. The additional velocity is nice but in this case I would sacrifice velocity for the accuracy of a Dasher, BRX, BRA. Feeding issues I can deal with. Ejection issues with a factory rem 700 action appear to be the bigger “potential” issue.

I put together a 6 Dasher hunting gun this fall. 22” Benchmark 7 twist. Shooting 103 ELD-X at 2910 according to my drops out to 500 yds. 32 gr of Varget with CCI 450. I went with the Norma brass as I didn’t want to fire form. Seems to shoot ok. I’d say build it; you’ll enjoy it. Very fun gun to shoot with very little recoil. It does have a MBM three port brake as well.

I'd do a 6 Creed, 6XC or 6X47L. Brass is now plentiful for either and it'll feed just great as is.

Just run the 6XC with a slower powder and/or run it at a slower accuracy node, and you shouldn't have barrel life issues. That's my thinking anyways.

I have a friend who shoots a dasher prone (sling) at 1000, and he is very satisfied with it, single loading.

I’m still on the 6mm dasher bandwagon. To me building rifle knowing that I’m going to run it nutted to save barrel life doesn’t bring the cool factor. Kind of like buying an old Chevy and putting a 383 in it, only to run it up to 3500 rpms so it lasts. I’m running that joker wide open, if she brakes I’ll fix it.

I’m up for a challenge of building a dasher on a rem 700 action. Emailed Dave Tooley last night to see what dasher reamers he has.

They will run when you get everything just right.

I'd sell the Remington action and put the money towards a good custom action that is known to feed/eject BR-based cases without modification. My Kelbly Atlas Tactical will do it. So will many others (I'm told).
