In my PPC with the 60 gr Sierra I started at 27.5 gr of N-133 an worked to 29gr. I got my the best accuracy with this bullet at 28-28.5 grs.

My question would be is your friend going to be shooting in the civilian world or the world of Short Range Benchrest.

There is a world of difference in how the 6PPC is utilized depending on it’s intended use.

30.1 of 133 works well for me in br.

well the main competition he will be concerned with is against me at the Ground hog field. So giving you that info he probably wants the best advice you can give, so he want have to here me talk smack all the way home!!

It would be helpful to know if it's a custom action as used in a bench gun or one of the civilian types like a Sako or Ruger. Use the Search function on this forum, you can read for days. I use a 6PPC I shoot matches with on occasion to hunt groundhogs with kills over 500 yards using the same loads, usually left overs from matches.

His rifle is a factory Ruger. I do not know what model. I think he purchased it new in the mid to late 90’s

 

[R.Morehouse]

With what he's got and what he is looking to do with it, I would have him look at 27.5. Tell him to put out a Groundhog silhouette at 300yds and see if that will work for him. Using a light charge his barrel should last for quite a while. Minute of Torso accuracy should be easy to achieve with that gun....

Is this rifle one of the Ruger 77 VT's in 6ppc? WD

 

[jackieschmidt]

While I haven’t seen one in quite some time. A couple of friends had several of the Rugers in 6PPC.

You definetly want to go by the loading manual protocol with these, not what Benchrest Shooters use in Competition.

With a 60 grain bullet, around 3150 fps to 3200 gps will be about right.

Also, Norma 6PPC brass will be a good choice for cases.

Buddy of mine shoots 6PPC alongside my 6BR. When we both shoot Column bullets (64 gr), he runs a grain less than me, and my normal load is around 29gr N133. So on the surface, 28 to 28.5 sounds about right given the slightly lighter bullet.

One of the most important things to consider is chamber dimensions. With a SAMMI chamber it can be all over the place. Fireform a few rounds and consider the final dimensions after fireforming. If you can start out with new brass that's best. Make sure you make notes of brass dimensions before you fireform. One very important dimension is chamber length. Measure with a Sinclair chamber length gauge and make a note of this dimension before fireforming. Other dimensions that you should make note of before fireforming are head diameter, headspace, neck thickness, loaded neck diameter, and lands contact CBTO with the bullet you will be using. Start CBTO (cartridge base to bullet ogive) about .010" off "lands contact". After you have fireformed a few rounds find the maximum load for your powder bullet combo by monitoring head expansion. You should not have more than 5 ten thousands expansion. Most loads for the 6PPC shoot best with the case loaded close to maximum. Do not use things like flattened primers and case head swipes to monitor pressure.

Absolutely correct! ^^^^

IF in fact it is a Ruger 77 VT chambered in 6 PPC, I own one, and have owned several. No need to hot rod it. It'll shoot fine with out going into hot benchrest type loads. It should be wearing a Wilson or Douglas 12tw barrel straight from the factory unless it has been changed and be wearing a laminated stock. I've never shot anything but 68-70gr bullets with mine and it'll shoot H322, Benchmark, and N133 quite well with them. JME.WD

I totally agree with this statement, pressure should be measured at the head with a mic

Yes it is. It has less than 500 rounds on it. Bore scoped the barrel and it looks like it is brand new.

We have tried a 55 grain Nosler and we can get it to under 1/2 groups pretty easy.

I've never heard that Wilson or Douglas made barrels for Ruger?

 

[WyleWD]

I doubt that they do now, but back in the early to mid ninety's some of the Ruger models sported barrels from them. Specifically the VT and #1 as I recall. Back when I bought my first one I called Ruger and verified it with them. And in a conversation with Stan at Douglas some years later he also verified that they shipped LOTS of barrels to them and several other rifle manufacturers. WD

I shoot n135 in mine.
A old friend that built guns suggested 135 over 133 because of the 26" bbl.
Shot the same load for about 20 or so years...27.5 grs n135. I tried 28 and the groups looked the same. Figured why use a half gr more ...
