6BR + 2206H (H4895)

G'day All

Just starting out doing some load development with 105/107 projectile. I have 4kgs  of 2206H in the cupboard and was going to use this. I've read that most use 2208 and the 2206H is more suited to the lighter 80/90 grain projectile. I have also read that 29 or so grains of 2206H can give  accurate results with the 105/107s (though I do note ADI states the max charge for the 6br remington is only 27.5)

Is anyone using 2206H or should I just leave it and purchase some 2208.


Thanks

Peter

Hi Peter,
By all means give it a go....I've never really understood why 6 br shooters don't use it more.

Many Dasher shooters in the US run H4895 (2206H) with record breaking results: so too do some accomplished f-Class shooters here in Oz.  Some time back I used to run 2206H in my BRX & it was great..I only moved to the slower 2208 when I began mollying projectiles.
With the slightly smaller capacity of the Br compared to the Dasher you could argue it's a perfect fit.

2206H is a great powder in my view!

Belly

Thanks Michael

I found a few forums post last night, seems people have had very good success with 2206H. Some state they are loading 29.5 grains behind 107 SMK's. I'll start at 27.5 ,with 105's jammed 5 thou, and work up in .4 increments to 29.1 and see what the that yields.


Thanks again

I'm happy to report that 2206H is showing some potential. Took the opportunity to  fire form some brass at our local fox shoot. Through together some 107 gr Nosler CC and 26.6 grains of 2206H sitting .005 off the lands and shot my best 10 shot group at 200 meters.  Then  jammed the same load .005 and shot a pretty nice 5 shot group at 300. (pity about the first that flew high) My daughter had the honour of  shooting the new Maddco  barrel out to 500 with the same load and shot her best ever group without evening trying.







My daughter and I  would like to thank Russell Le Maitre from Group solutions for his work sourcing and fitting the new barrel. He was great to deal with and as we really didn't know what we wanted we just left it in his capable hands. The 6 Br is a lot more pleasant to shoot than the old 308 that's for certain

Great stuff Peter getting a 6 BR to work is very very rewarding, you might even try the 103 Copper heads as your velocity is up a bit and you can put about 1 grn more in most. Do you know how to see pressure in your case, flat primers, slightly sticky bolt to lift after you have fired it. Another good thing to play around with is neck tension which is really handy when reloading multiple times.

cheers and good shooting
Les

G'day Les

Thanks for the tips. I have been reloading for a while, so I'm aware of the signs to look for when working up loads. Most of my life though its been hunting rounds, this precision reloading is a whole other kettle of fish. I only acquired one neck bushing so Ill have to grab a couple of others later so I can play with neck tension. I have some copper heads for the 308 I never got to try so Ill have to grab some for this and make certain I give them ago.  Yeah it is rewarding, I think I enjoy the reloading as much as the shooting sometimes and its even better when I can get my daughter out in the shed to help. Pity she is not as enthusiastic when it comes to that aspect of our sport as she is when it comes time to shooting the things.

Thanks again

Hi,

Where are you based mate, I have some copperheads I'd be happy to give you to try. If you send me an email with your address I'll post them, or I will be at the pro cal this weekend if your going.

Regards,

Deane

Dean


 he is from the bay. If he wants I am happy to bring then back from the shoot on the weekend to save postage.


Cam

Cameron,

No worries mate ill bring them and give them to you

G'day Deane

You're too kind, can't thank you enough.
Hopefully I'll get the chance to repay the favour one day.

Thank you Cameron also.

I can bring a handful of Sierra 107 match kings if you would like to try those as well m

Hi chappo

As much as I appreciate the offer,  I just bought what appears to be the last box of 1000 107 smk's in the country for a vary decent price. A friend and I went halves, I should have them in about 4 weeks. We figure they should shoot good in at least one of our rifles, otherwise we might have a stack to give away :)

Thanks anyway

Peter,

No worries mate, since your from the bay, Anthony should be able to lead in the right direction with the copperheads for the 6BR, he sure has his humming 👍

No dramas. Just remember to batch them by ogive to base. My last two 1,000 boxes varied by up to 0.014.

Well done guys, this is what fly shooting is about helping each other out.

Tip when you fire a round out of your 6BR what is the actually measurement of the fired case.

Example: fired case is 269 so you will have a 270 neck as general rule of thumb is about a thou difference

then you measure your bullets so your bullet measures 243.5

Now measure your case wall thickness if you have prepped your cases they should have a uniform thickness

So your case wall thickness is 14 thou so .243.5 +28 thou is 271.5 and you know your chamber is actually 270 so you will need to trim your neck wall thickness to 13 thou to give you good clearance and then a button to start using would be a 266 when you push a projectile in that will often grow your neck thickness loaded by 2 thou so your finished loaded neck is 268 which is a good clearance without to much brass movement.

hope this helps

Thanks Les that's good information to know.

I asked Russel for a 270 neck. After talking to several blokes at the range I turned my lapua brass very slightly,  just enough to take the high spots off. A loaded round is approx .2685  I ordered a .266 bush to start off with as I understand the neck springs back approx .001.

One thing I'm not exactly certain about is how far you should run the necking bush down the neck. I have been going half way on the assumption that if I wanted to try a little more neck tension I could run it 2/3 to 3/4 of the way down or a  little less then half way if I wanted a little less tension.

Is this typical practice or should I be running the bushing all the way down the neck and have different bushing if I wanted to reduce or increase tension ?  Is there any benefit to doing the whole neck or is it a try and see what works best in your gun sorta thing ?

To start with size the whole neck…it's easier & it won't hurt accuracy.

Afterwards, if you feel the need, take note of how far into the neck your projectile sits after seating ( just hold a projectile next to a loaded round for a rough measure )  & then neck a good 400 thou past that to ensure the WHOLE  projectile is grabbed by the case neck.

Better to much than to little.

Belly

errr….that should read 40 thou….

Belly

Thanks Michael, Ill give that a shot.

Deane

I thought you were too kind when you said you would send me what I thought was going to be a dozen or so projectiles to try.  Imagine my surprise when Cameron gave me a box with a hell of a lot more than that in it. I sincerely thank you (as does my daughter), you have been way way too kind and like I said before, I hope I get the chance to repay you, and  buy you a beer (or several) one day soon. Ill let you know how we go with them.

Congratulations on your win in Canberra also. I take it you were using copperheads :D


Thanks again

Peter
