29+ grains seems to be most popular load for 6ppc. That is 4-5 grains more than Hornady's maxium. Nosler's newest manual does'nt even list 133 as a powder for 6ppc. Any comments? Thanks:)
 
Custom actions.

Custom barrels.

Lots of experience.

Don't try this in yer squirrel gun.

Comment-benchrest shooters can't read, won't be told, and can't be persuaded to change.

Seriously, what we use for loads in our custom actioned benchrest rifles shouldn't even be attempted in a factory action, PPC barrel and commercial brass (PPC can be made from Remington 7.62 x 39, for example).

Benchrest shooters also start at lower loads and work up to where that particular barrel/action shoots best and that sometimes is pretty hot, pressure wise. I'd estimate some loads exceed 70,000 psi where your "factory" loading manuals usually break off at about 52,000 psi.

Your questioning a 29 grain load is novel to some benchrest shooters since they consider that a mild load.

Then, there is the exercise where the reloading manual publishers look at their data from a lawyerly viewpoint.

A very serious caution from me--- don't try any of the above unless you are really sure of what you are doing and why.
 
Exactly what load does Hornady have for the 6 PPC and N133?
Because the Vihtavuori manual has 28.2 as the max with a 68 grain bullet for the 6PPC USA which is pretty close to the 29 that you mentioned.
5 grains less would be 24 grains and that doesn't even meet the Vihtavuori minimum load of 25.2 so if what you say is true it would lead me to suspect that data.

Due to the recent prevalence of "lawyered" reloading manuals, about all they are good for is as a source of a safe starting load to work up from.

If you look at their data, you will find that most of these reloading manuals publish data with Sako brass instead of 220 russian Lapua brass which is what the majority of shooters use. There is a significant difference in case capacities and pressures that these two kinds of brass will tolerate. Why these companies are still stuck in the past and refuse to update their data to what is currently being used is beyond me.

I sometimes see N130 listed in data but until we see Lapua brass being used in their testing, N133 will probably be ignored as well. No matter. We will continue using what works despite what the manuals say.

Tight tolerances, attention to detail, the very best in components, and the Lapua 220 Russian case allows us to shoot at a little bit higher pressure than what most manuals would consider maximum.
But have you noticed the Factory specs for the ultra mag familly of cartridges. I believe they top 60,000 psi. And that is fired in a open magazine Factory Action.........jackie
 
I have used a sako 75 6mmppc for Nearly five years now!!!!

My hunting load is 28.7 grains of vit 133, 65 hornaday ballistic tip, fed 205m primer, lapua case,,,,

Benchrest comp load,, 26.6 grains of vit 130,, 69g Berger, fed 205, lapua case,

This rifle has been pillar bedded, recrownd,, I have fired over 4500 rounds and it is still winning factory class comps,,

As has been said you have to work your loads up safely

All the best, Darrel
 
I see where the latest Lyman catalog lists H-335 as the most accurate powder for the 6 ppc with 70 gr bullets, and Varget as the most accurate for 60 gr bullets. Sako brass of course, because that is the factory brass available for the ppc.

The question is, how much longer the 6ppc will be our accuracy champion. It looks like the 30 BR and/or other small capacity 30 calibers are nipping at its heels. The 6 ppc may go the way of the 222, once the many advantages of shooting a 30 cal bullet are fully realized.

With lawyers and judges running the country, you need to cover your backside six ways from Sunday, or you will be sued out of existance. Particularly with something as un-PC as shooting and/or reloading. The lawyers have the power in our society.

Agreed. But it would not be against their bounds to at least use components updated in the last 15 years. Honestly, has anyone ever shot H335 and Sako brass in any registered match in the last decade? All I'm saying is it wouldn't kill these guys to get out in the world, see what's going on, then get their kiesters off the chair and into the lab and give the shooting community a little taste of what is really possible with the 6ppc instead of just regurgitating the same old data year in and year out.
