6.5x47 Loads

[MartyK2500]

There are a few threads with the 6.5x47 included, but none dedicated to it from what I have seen.
I just love this caliber and will set up a second one soon.
I am curious, what are you running for loads with your 6.5x47 L?

Here is mine to start this off...


26'' IBI M40 profile
1:8
139 OTM Scenar
38.6gn H4350
CCI 450
20 thou off JAM
2750FPS

On avg will net me 1/2 MOA, sometimes it will go sub 1/4 MOA and rarely get into 5/8 MOA.
For some reason the load can shoot but something isn't as consistent as should be.
Only 5 shot groups at 200M are counted, I don't bother with anything with less rounds shots or closer.

I'll play;

26" Shilen Select Match
1:8"
139 gr Scenar
39.8gr H4350
CCI 450
20 thou off
2820 fps
SD 7.5
Avg group size high .5 or low .6 MOA
Regularly 3 together and 2 just above which is most likely me but 3 out of every 4 groups look identical.

Your load is very close to the 6.5 guys load shown in this table.
As I go higher and close to 39.6gn load, in the past, I had pressure signs, while still having a smooth bolt lift.
Yourself, are you into pressure signs and ''bypassing them'' or there are no signs at all?

Just for conversation, I have seen a lot of guys run into pressure with the 6.5x47L and ignore it, as the cartridge is capable of taking it, or so many guys say.
Myself have ran a few high pressure loads but am then scared of running them in the rain and have no buffer zone whatsoever anymore...

I was loading it higher without pressure signs until I shot a match in sideways rains and experienced some heavy bolt lift.

It is common it seems to hit nice velocities without pressure in this cartridge,
Which has me thinking, what’s the component related to pressure signs?
Barrel?Action?Brass lot?

I saw pressure at 37.4 (ejector marks) with the ELD-Xs, then backed off 0.2 and they went away. I'm working on an alternate load with 140gr Berger hybrid, ran it up to 37.6 without pressure. However, in the interest of better groups and barrel life I will stick with 37.0. To your question, I think it's a combination on all of the above (also temperature/environmental, primer type, headspace etc.). Any of these variables can cause an increase in pressure, manifest themselves differently depending on the rifle.
