6.5x47 Berger Bullets

[MahtewsSB]

That was indeed helpful. And as of this weekend i will have a reloading press and brass and bullets will be on the way shortly there after. I will be using the new magpul 700 hunter stock for this rifle and their detachable mag system for it which runs AI mags

I had mine throated for the 140 Hybird to be seated at 2.850 to fit AI mags and it works very well with all bullets down to the 100 NBT,,

I shoot the 123 Scenar and 42.7 H4350 at 3,000 fps and the 130 VLD and 39 grs RL15 at 2950 and with the 140s 2800 is as fast as I can go with good accuracy

mine is a 28 inch 8 twist 5R Bartlien

Sounds like a belated Christmas is near this weekend lol .

If you've not watched any of Erik Cortina's YouTube videos check out the one on making a proper dummy round.

If you have the magazine you'd like to use along with the components of the cartridge that you plan on using then you will be able to make a dummy round and send it to whoever is doing your smith work to see if they have a reamer to accommodate your needs.

Good luck and have fun.

Haha yes, this whole project has been a culmination of christmas money, what is left of my student loan refund, and now my tax refund has been acquired as well. needless to say my gun budget will be 0 for a year or two after i finish this

I didn't realize Erik had videos on youtube. I will definitely check them out. I have been reading extensively through his thread about long range load development at 100 yards and I have picked up a lot of info and look forward to applying it

My barrel is a Krieger 8.5 twist that 28 long with a .292 neck loaded round is .289-.2895 I'm turning my brass just enough to clean them up. If you plan on shooting 140 all the time a 8 twist would probably be better although there are many running a 8.5. My next barrel is going to be a 32 inch straight tube. I'm just curious if there is more speed to be gained without the pressure. I think Eric shoos a long tube maybe he could chime in here

ok guys i'll be ordering my barrel from krieger monday and this is what i have planned. let me know if i am missing anything or if there is anything else i should be considering in the process

28" stainless 6.5mm barrel
#17 heavy varmint contour
4 groove
1:8" twist

i'll also be having them go ahead and chamber it in 6.5x47 for me and i will be sending them my action to fit it to the barrel. from what i now understand, when i order it i should inform them that i plan to use the 140 vlds and that the rifle will be mag fed from an accurate mag which has a 2.950" max coal, that way the optimum throat depth can be determined? is this correct? am i missing anything?

I shoot a 32" barrel. That allows me to run same speed at lower pressures, and when I set it back, I can cut off 4" and end up with a 28" barrel, which is still great for the "47".
I have always shot 139 gr. bullet around 2,880 - 2,930 fps. I use Brux 1:8" barrels.

MathewsSB, who is going to do your barrel work? It appears you will get the barrel maker to do the entire thing, who will that be?

 

[MahtewsSB]

Erik I will be getting the barrel from Krieger and yes I plan to have them do all the work as well

You will be fine, you don't need accurate mags, the standard AI mags have enough room even with a .198" free bore and a 140 Hybrid. That's the beauty its a true short action cartridge even set up with max FB. If you like the Accurate Mag they are fine and will give you an extra 100 thou.

If you're not interested on turning necks my pick would be a .2945 neck with .180 free bore.
This would still allow you to stay off the lands (being a hunting rifle) and still leave room in the case for powder and also keep the heel of the bullet out of the neck shoulder junction.

I was unaware that the barrel maker you chose still did chambering , in any event good luck should be a nice shooter when completed.

when you guys mention freebore, is that the distance from the beginning of the throat to the beginning of the rifling?

i don't remember if i've mentioned it yet but i am new to reloading as well so im not 100% sure on all the terms yet but that is what i think you are referring to. please correct me if im wrong

The throat is the free bore if you will...

Here is a reamer print that you can check out and get an idea of what some of the numbers mean.

This particular reamer print is a .170" throat and a .2930" neck.

ok thanks for clearing that up for me.
