Hey there, I've been looking for data concerning above combo. Found some stuff on the internet,but thought I'd ask here.
So can anyone give me a min /max load for this?

6.5x47 Lapua
123 g scenars
Varget
CCI SRP

20 inch barrel

Thanks

Starting load for Varget 32.6 to 36.2 max. You might get better results with H4350, starting 37.8 to max 42. Also VV N150 is worth a try.

Hodgdon Data

Yes , I've seen that,and I do have a box of 123 amax bullits.
But I was looking for the scenar data. Just in case it was a bit different.

I only use load data as a safe starting point, and I only consider the bullet weight. After the starting load, I use my own testing to determine the best load for my gun. I find those load recipes that identify some specific bullet and load to be an "accuracy load" to be essentially worthless, unless their gun and my gun are identical...

Lapua publishes loads for their bullets, but they also make Vihtavuori powder, and only list their powder with their bullets. Here are their recommendations for the 6.5x47. But no Varget of course...

The Accurate Shooter Load Map does show one load for the 123 Scenar and Varget of 37.7 grains. That is beyond Hodgdon's recommendation, and is obviously a load you would want to work up to very carefully. Once target shooters identify a velocity they feel is a sweet spot, they will push the limits to get there.

Yes that's the article read, it says 6.5x47 is good for 63090.
Hodgdon is saying their max load is 51400. It appears that is a bit low.
Hodgdon is using CUP, I wonder if Lapua is using the same measurement???? Or does that even matter?

I think it is a little bit of a game that is played when a cartridge is certified by SAAMI or in this case by CIP. The maximum pressure is more determined by the barrel/action than the actual cartridge. So you get certain cartridges that have a higher pressure rating, but the gun manufacturers put them in the same barrel and action as a lower pressure cartridge. At the end of the day, you have to watch for signs of excessive pressure, and make your own decision as to how much is too much. Some will play games to disguise pressure signs, like looking for a harder/tougher primer, or by bushing the firing pin to reduce clearance and visible cratering of the primer. But it doesn't change the actual pressure in the gun. I load my 6BR to just over the max recommended by Hodgdon, but I get my desired velocity, and don't see any signs of pressure.

I think all of this just tells you that recommended loads are just starting points. You have to determine the end point.
