re-chamber

i have a varmit rifle chambered in 6 ppc with a .262 neck dia. it has a 14 twist barrel and it is about 20 inches long. i shoot 70gr. ballistic tip bullets pretty much in 1/8 inch 5 shot groups at about 3200fps. if i were to chamber this in 243 ackly imp. with a .265 dia. neck, it no doubt would increase the velocity but my question is would it work ok and could i go up to an 80gr ballistis tip bullet or would this caliber work at all with this 14 twist barrel and if so with what bullet. i want to do this for one reason and that is to eliminate all the fuss to make casings including the cost to buy them. this way i buy them about any gun store,true up the necks , load them, and shoot them.
thanks, double s ( sam )
 
Have you considered having a 6PPC no turn neck reamer made? Seems like it would be easier. Don
 
still would have the problem with casings.... cost,shipping,preparing.... and i still would like to know if this would work if i decieded to do it.
 
could this caliber stabalize a bullet with this twist and speeds ?
 
so what your saying is this caliber would not work reguardless of what bullet weight i used.
 
The 80 grain boat tail may be a little long. Having said that.
I shoot 75 grain V-Max bullets out of my 6BR with a 1 in 14 twist barrel. It is very accurate out to 600 yards. I have not tried the combination past that. You are not going to get all the performance out of the Ackley with the 20" barrel though.

Here is the down & dirty solution. The new Norma 6PPC brass is quite tough. Lou Murdica doesn't make mistakes, and so he's reported. With your chamber, you can have the neck only opened up by a good gunsmith, which will take care of needing to turn necks, the rest of the unwanted "prep" part.

I see you like speed, and if you want a faster 6mm. go for it with a new, longer barrel. My personal preference for speed is a 6 Ackley (aka .244 Remington improved), but the 6mm/06 is a fine round, with correspondingly shorter short barrel life. But you knew that. 30-inch barrels are good here.

Meanwhile, the current rifle is balanced for the barrel length & chambering it has. It is a fine 350+ yard varmint rifle, with a varmint-shooting barrel life of, one would hope, about 3 times the life of the the 6 Ackley or 6/06.

BTW, one of the things I noticed with my 6 Ackley was that as the throat wore, velocity dropped off. It was still accurate -- kept winning wood in 1,000 yard BR -- but after 400-500 rounds, the velocity was off 150 fps. It's expensive to go fast.
 
Geeze, give me that Rifle. 70 grn ballistic tips intp 1/8 five shot groups. You do know that is .125?

That barrel is way too short for a 243mm Ackley, that 1-14 twist might stabilize a short 80 grn as long as the jacket length is under .900.

Its just right for what you have now.......jackie

well this rifle used to be a benchrest rifle, it was built on the XR-100 rem single shot action and the action was all trued and sleved, it has a shilin 6 grove barrel and it has a 1oz jewll trigger, the one piece davidson scope base and kelby rings. all i did was put it back in the original XR-100 stock of course i had to open it up to fit the barrel and i put a 6X24 weaver scope on it. when i shot 66 grain and 68 grain fowler bullets out of it when was a benchrest rifle it shot .100 to .125 consistently. i just decieded i wanted to make a varmit rifle out of it and the 6ppc just aint getting it for distance. 243 brass is very easy to get and i was just curious to know what i could do with this 243 cal and the 14 twist. and i thank all of you guys for the input cause i know darn well you all know more about this than i do. maybe i will just chamber it in 6BR with a .262 neck and i think i already have that reamer.. that should shoot fairly good to 350 yds and that brass it fairly easy to come by.

Think I have a solution for you. Put it back in that configuration, warranty it will shoot .100 to .125 consistently, and name your price.
 
i am done with benchrest with that gun i still have a 30x47 that will shoot just as good and besides its better for score shooting. so the ppc is history i will probably make it a 6br. thanks for all your input and you all make it sound like .125 groups are hard to do, well maybe so but with only 5 or 600 rounds out of that ppc i guess it hasn't started to go to downhill yet. oh well it was fun while i done it. thanks
 
I like Charles idea with the new norma brass. i have shot it and continue to shoot it and its good stuff. If you need more speed shoot a 50 or 55gr bullet. Good luck! Lee

Indeed we do. Oh, you get an occasional small one. I have a (one) .082 in registered competition. But you're talking as if it is common, consistent, etc. for that rifle. Go look at the aggs for the Super Shoot, the NBRSA group Nationals, the IBS group nationals, any shoot where all the national-level competitors are present.

If .125 MOA 5-shot groups are common or consistent with that rifle, I bet it would sell real well. In fact, if you can back up that claim, I'll trade you a brand-new barrel blank of your choice for that old one.
