6mmBR Fly Rifle

Well I've gone and done it. I've bought a BR rifle, 6PPC for the shorts and 6BR for fly.

After my first 500m fly shoot in Batemans Bay using my .284 barrelled Tikka T3 I realised a "real" target rifle was a better option. I struggled there with a load that was shooting 1/2 MOA in another stock suddenly struggled to stay on paper in its new stock. I guess new bedding a new round of load development is required.

So I purchased an old Hart Rem clone with two barrels, a 6PPC barrel with two rechambers under its belt and a near new 6BR barrel. I've now purchased 6BR lapua brass, Berger 105gr VLD's, Wilson dies and all manner of other gear that goes with a new caliber. I'm ready to start load development on the BR  and I'd like to have it shooting for the Canberra shoot in a month or so.  

what I'd like to ask is

"Am I on the right track?" 6BR 1:8" twist 26" barrel, Lapua brass, Berger 105 VLD'S , CCI BR4 primers and a stout load of 2208,  I also have 2206H, 2209 and BM8208 as an option

I know many of you are probably madly prepping for next weekends shoot in Wagga so I appreciate your responses

Steve

Most common load is 29-30gr 2208 with 105-107gr pills.  Bring it along to Wagga mate and have some fun.  Usual caveat of work up load.

Hi Steve,

Great to hear, and yes you are on the right track.... Around 30 grains of 2208 should be the solution.....

Here is my fast track solution

Start at 29 grains 10 though off the lands and work up in .4 intervals until the groups tighten up (and the load above and below is good)..watch for preassure.., then try the best load jumped v jammed... make a decision and stick with it for those pills

Then, if you have time, try plus and minus in .2 increments of powder until you find the middle of the best charge (gives you flexibility for temperature etc).

I suggest all load development at 300 on a calm day, or 200 if slightly windy.

Cheers & good luck

Hi mate i brought a 6br and using 2208 i found the best projectile weight to be around the 95 to 105 range the copper heads work very well but recently i shot the 95grn VLD bergers at 30.6 - 2208 and the group was fantastic.

The 6BR case is very efficient and produces great loads and accuracy as does alot of other cases the Dasher shoots fantastic with a little more Velocity but in comparison to wind drift there is nothing in it you can actually print on the target.

You should always choose accuracy over velocity...

Hi Steve,

Great to see you working at it and making progress..... you will learn lots as you go along.

A couple of things that I would suggest...

1) 0.1 of a grain either side of a true good load should not make that much difference...  The object of load development for powder charge is to find a "node" where you have good accuracy either side of it.... .this allows for temperature differences and other things that effect pressure slightly.... When you do your testing you are looking for a the middle of an accurate range.... preferably where they all print about the same vertical on the paper....

2) With your seating depth, as you changed 2 things at the same time, you will never know if the seating depth improved things or if it as the powder charge increase that made the difference..... I would go back to 0.010" jumped and sort out the best powder charge... then try 0.020" jumped and 0.10" and 0.15" jammed to see what the barrel and projectile like the most.....

In an ideal world a 300m range would be good for your development..... but by all means do it at your 170m.... but really look for consistent 5 shot groups without the flier.

Have you checked your rest for movement, rear bag for stability and does the rifle track back and forward smoothly and return to point of aim every time ?  A rocking front or rear rest, or gripping on the bags will cause a flier also.

Good luck & enjoy it..... it is all part of what makes it rewarding !!

Cheers

You're a step ahead of me Steve.

I've spoken to both Anthony and Les at Batemans Bay, and Les again at Silverdale.  Was maybe going to try my T3 Super
Varmint in 6.55x55, but just hadn't made the jump.

Have been shooting benchrest at Silverdale for only a short while, and have already upgraded my benchrest rifle.
Bought Dennis Tobler's outfit with HV, LV and Sporter barrels, and it also comes with a 6mm BR barrel.

So I'm ready to follow exactly the steps you're going through, so this  is a great thread for me as well.

Will try and post my development progress over the next 4 to 6 weeks.

Hey tony

If be keen to get out to silverdale for a shoot some time. I'm yet to play with the 6PPC as I'm keen to get theBR ready for the canberra fly shoot but I need to complete fireforming and load testing

I'm going to try for Sunday. This will be my first time loading at the range so I will probably forget something :fp:
