load data for 6ppc

[grovey]

Since I don't know, and I don't see the answer above I have to ask... What is the problem with hot loads in the Sako? Is it the extractor,or?

Sako has 3 action sizes dependent on the cartridge they were offered in. Not sure if the PPC was offered in the A1(smallest) or A2 but it is rather petite as compared to a Remington 700 style....less metal surrounding the case therefore can not handle the same pressures as well as looser tolerances as compared to custom 700 clones.

I see. I have a ppc repeater built on a 700 with a Sako extractor and was told or read where I shouldn't push it hard because of the extractor.

thats a whole nother issue. the sako has miniature lugs compared to a remington on top of the extractor. at least on a remington you have the bolt nose recess.

There are two primary reasons why most, if not all, benchrest shooters build rifles using custom receivers with matching bolts. For accuracy, and to be able to withstand the higher pressures associated with higher pressure loads.

Now I have not been witness to any accidents related to pressure related accidents in firearms and I have no desire to. With this said I stick with what has been documented by the powder companies and bullet companies in their available load data books, manuals and their online websites.

Now sometimes, for example the powder bullet combination I opened this thread with, are not or never have been tested by companies and officially documented. So This is where I try to ask around on reputable forums such as this one and read what the members recommend and make sense from a safety point of view.

BUT some shooters have maybe never gone by load data, or maybe they only have had custom benchrest rifles and loaded by the seat of their pants, or maybe some just like watching the number on the chronograph and watch primers for danger signs, whatever the reason, they have like myself never witnessed an accident. Yes back to the accident. To cut through the chase, I want to go home and see with both my eyes my four beautiful daughters and wife, and feel them with my hands and fingers. I am glad I have not witnessed an accident. I want to keep it that way too. this is my reason why I do not venture outside commercially recommended loads for any of my rifles. That is also why just finding that first node is totally fine by me.

Just a update for all those who had input.
I found my powder! LT-32 is the one.
I gave the LT-32 a try using Berger's 6mm BR column bullets. This particular batch I received is 64.0 grains, where as I guess usually the batches for some reason are 64.2 grains. Now I am shooting groups that I was expecting to shoot all along. Biggest group I shot was 3/8" center line to center line of furthest apart holes. Smallest group was .250"
center line to center line of furthest apart holes. I was quite surprised to find the lightest load of LT-32 was the tightest group. The higher the load I went up, the groups went vertical or horizontal or just plain and simply opened up in a even pattern. I shot six different five round loads/groups. I know that there is some meaning with what is going on when there are verticals/horizontals, but I need to research this a bit to figure out that detail. I shot free recoil. Very pleased with the powder.

Interesting.

My Sako 6ppc likes the Berger Web BR 65s a bit better than the 64ish Columns. Both can shoot 1/4” at 100y and my brass consistency is still not where it could be.

I have tried H322, H335, and Viht N133. My limit load with the N133 was around 27 grains and it was only 60f. I actually prefer the 322 and 133 as the stick powders are much less messy.

I have another Sako 6ppc on the way. They are great rifles considering they are non-BR designs.

By the way, accurate powder list loads for LT-32

^ those are a good start for sure

Western Powders has released a Version 5 downloadable manual that shows LT-32 loads for 1 55-grain, 2 68 grain, and 2 70 grain 6mm bullets. They also have Version 7 manual that I just ordered but have not received for $2.99.
