switch barrel gun

[Big Man]

Sorry for the stupid question, but am I correct in assuming that I can use one rifle and switch between a 6ppc and 30ppc barrel (for group and score)??

And does anyone know whether the Jackie Schmidt 30PPC reamer can be ordered from PTG??

Thanks

Big Man,
Yes you can change,but you must be sure that you have a standard bolt face and not a PPC bolt.Also you need to be aware of the weight restrictions.
And if you decide to go this route,I have the reamer you need,it is a PTG reamer that Jackie uses and has cut only one chamber.I will let it go for $125.

A 6PPPC and a 30PPC both use a PPC bolt face. You will be able the switch back and forth easily.

Plan ahead for making weight. A 6mm barrel will weigh about 3 ounces more than a 30 barrel of the same exterior dimensions. I was surprised by this the first time I saw it on my scale, so I figured the volume of both bores in cu/in, subtracted the small one from the large one, and multiplied by the weight per cu/in of SS.............sure enough, it came out to nearly 3 ounces.

Thanks guys, my logic told me this will work, now confirmed. Has anyone tried the 30PPC in score competition yet??

Hi Nick, why would the PPc boltface not work? Both use same case, so should work?? Are you shooting a 30PPC?? Any good??

I shot a 30 Junior, which is quite close to a 30PPC, at the IBS Score Nationals this year and took 3rd at 100 yards with it. They do work, there is no doubt about it.

I assume the custom route would be the only way to go for reloading die's, etc for the 30PPC, who can one contact for these?

Many thanks for all the responses.

Get a Wilson 30 cal Blank die and make a custom seater using your chambering reamer, and talk to Harrels I am sure they can supply you a PPC sizing die opened to .308 this would make a reasonably inexpensive set of dies.

Yes indeed the 30ppc will shoot. I dare say it will shoot group right along with a 6ppc, given equal guns. The recoil is a tad more than a 6ppc since most use 112-125 grain bullets. The recoil in foot/pounds is roughly twice that of a 6ppc. Rough calculation, 6ppc, 10.5# rifle, 68 grain bullet, about 4 foot/pounds. The 30ppc, 10.5# rifle, 118 grain bullet, about 7-8 foot/pounds. For comparison a 30-06, 9.5# rifle shooting a 165 grain bullet results in about 16-17 foot/pounds recoil. Never noticed shooting at game but a bit tiresome shooting a match from a bench.

Dave Kiff at Pacific Precision has my reamer on file, it has a zero freebore, .332 neck,and a trim to length at 1.495.

Yes, all you have to do is change barrels. I head space the 6 and the 30 the same.

Mike Southard up in Oklohoma had a set of dies made by Harrels,and they work great. I made my own, using a Redding 6PPC fulllength die with the neck portion reamed, (with a carbide reamer), to the correct size to neck size the cases. The die also sizes the body, bumps the shoulder, and decaps.

I made my seater out of a Wilson Competition 30-30 seater. Just cut it to length, and ream with the chamber reamer. Makes dead straight ammo.

It was mentioned about weight. I had sort of a funny occurance when I did a barrel for Mike. He sent me a barrel off of his Farley LV to use as a pattern for the 30PPC barrel. I did all of the carefull measuring to insure that the barrel came out the exact same weight, but when I finished, the 30 barrel weighted a few ounces less. That is when it finally dawned on me that it had a much larger hole in the middle.........jackie

Jackie , how does the 30 PPC perform vs. 30 BR, accuracy & velocity. Just curious. I have PPC & BR , both 6MM. I use same action (40X) w/different bolt. For BR I use bolt from .308 700 deer rifle. (works nice)
Thanks

Switch Barrel,

Big Man,
I must have been half asleep,I thought that you might be going from PPC to BR cases and wanted to make sure you had the correct boltface,but no I have not shot the 30PPC in any matches,I started the project and ran out of time and gave up and just built another 30BR.Another preson who frequents this web site has some experience,try asking Jim Wooten about his work with the 30PPC.

Here was my idea when I developed my 30PPC.

There are multitudes of shooters who have Rifles with PPC bolt faces. As far as the Rifle is concerned, to build a accurate score Rifle, just screw a 30 PPC barrel onto the Rifle.

Another factor was the idea that IBS was going to institute a true LV class. There is enough difference in the recoil to warrant a 30PPC in a 10.5 pound Rifle.

There are also a lot of clubs, such as Tomball, that just shoot 100 yard club matches. The 30PPC is deadly at 100.

Which is the better??. For all around score shooting out to 300 yards, the 30BR is the logical choice, especially in a 13.5 pound Rifle. It holds more powder, you can make better use of 118 to 125 grn bullets. Since I cannot tell the difference in the accuracy potential of the two, the nod goes to the 30BR.

That is, unless you are primarilly shooting at 100 yards, and your Rifle is basically a LV weight Rifle with a PPC bolt face.......jackie

This is my scenario exactly. Many thanks for everyones input, highly appreciated!
