Pardon the newbie question, but can some one explain the difference between these cartridges.

Thanks in advance.

Well, the 6BR and the 6mm Rem are a standard .473 head. The PPC is between the 223 and standard size. The 6mm rem is a necked down Mauser, the 6br is a shortened and necked down 308. The PPC is a necked down and blown out 7.62x39.

The 6mm rem has almost twice the case capacity as the 6PPC, with the BR closer to the PPC than the 6rem. With lighter bullets, there isn't a whole lot of difference between the BR and the 6rem. HTH, Dutch.

And I hear they are thinking of changing the name of the Bench Rest shooting clubs to the "6PPC" club!!! GHD

FWIW,
I've had recent experience with two varmint rifles chambered in 6mm Remington. Both have good barrels, a Rem 40X & a Hart, and both are stocked in McMillans. Neither gun has impressed me coming or going. I dunno what to tell you on this, however, the 6mm Remington just does not impress me with accuracy or shootability.

My 40XB-KS is going to Clay Spencer to be built into a 6mm BR... Will report back in a year or so...(grin)

Regards, Matt.

I got my 6 Rem working, but Matt's right. It can be a persnickety SOB. Many of the 6's can be that way, it seems.

here's a couple of pictures from Saeed's reloading pages, one is the 6mm Rem the other the 6mm BR. If you go to some of the component manufacturers websites, you can get the exact dimensions for each.

While not as "fast" as the other 6's mentioned, I have a 6PPC in a varminter and love it!

I am hoping to make a trip to Canada or the States this year for some varminting to really get to try it, so far I have used it for a little coyote calling in Canada, and for hunting here but would like to try it on some long range p dogs and the like, I don't think it would dissapoint!

I have a 40X Remington in a 6BR. It came out of Remingtons custom shop , has a tight neck and the twist is such that it won't stabalize over 80gr bullets. The rifle consistantly shoots in the .2's and .3's . I load 70 gr Ballistic Tips and 70gr Hornady SX's at a little over 3,300 fps, not near as fast as a 6MM Rem and as mentioned a little faster than the PPC. The PPC and BR both are short and fat and use a small rifle primers, theory being that adds to the accuracy of em, both being designed as benchrest rounds. With all due respect to some of the wonderfully accurate 6MM Rems I would dare say the typical PPC or BR will be more accurate than the typical 6MM Rem. I think the Rems probably a better ultra long range rat smacker, I limit my BR to around 400yrds with the 70 grainers I shoot.---Shoot Safe---montdoug

Too bad some people have had bad luck with the 6MM Rem. , I for one have not . Deer , pigs , and coyotes have all fallen to mine . The only time I can remember a second shot is on a pig . By the way it sure punches nice holes in paper also .

Two weeks ago I shot in a varmint rifle match at the local range.First and second places went to a Father and his son.Junior took first with a Sako single shot 6PPC and Dad followed with a Sako in 6BR,rechambered from a 243,10" twist.They are accurrate little cartridges,make no mistake...I placed fourth with my VSSF 223,maybe I shoulda shot my Sako........

I'm purchasing a Remington 700 VLS in 6mm Rem. Maybe someone has experience with this
rifle in this caliber. It's a risky purchase because of the new .243WSSM coming out which might be more inherently accurate. I already own a .243Win. The 6PPC seems to be far and away the best but I don't care to shell out the big bucks for a Sako right now. The Remington
VLS in 6mmRem. has a 26" heavy barrel, and I'm hoping for .4" (5 shots/100yds.) Does that seem reasonable?

All, Any you guys with the 6mmRem. want to shoot in the 2s and 3s with your rifle(75Sierras and 95VLDs) please e-mail at jarhty28@hotmail.com or jcpython357@aol.com, If these loads won't shoot good, probably nothing will. Jay.

Had an old Ruger 77V 6 Rem. that was a very good shooter out of the box, but never in the 2's or 3's,BUT i have a Shilen-barrelled 700 6 AI that'll do it with some 70 grainers, and the 87 Horn BTHP. Actually come to think of it, it's never been quite that good, probably 1/2" or less, average.

The 6BR
Varmint and benchrest started off very similar in the beginning, but not anymore. Generally speaking, varmint hunters want the fastest, most explosive round to reach out and touch something, BR's aren't into velocity, they want to 'tune' their rifle and round for accuracy ONLY, speed doesn't matter.
Therefore, varmint hunters generally use long barrels, and more powerful cartidges-increases velocity and the limits of the cartidge. lengths from 24-30" are the norm. Benchresters on the other hand will use short stocky stiff barrels-to tame the occillations/harmonics of the barrel. 18.5-21.5" barrel lengths are the norm here.
Varmint hunters will generally find the fastest load with an acceptable level of accuracy and a bullet designed to exploded. Benchresters will literally tune their rifle like a piano. Sometimes they find a great load and then cut the barrel of in 1/32 incremints til it HUMS. The perfect occillation of the barrel in the firing sequence deals with harmonics. So here you have very different purposes, the BR series was origninally designed because of the shortage of ppc brass.
PPC is THE standard for accuracy, but brass was expensive. The BR series is extremely accurate, but benchresters weren't satisfied so they started to shorten the cases to acheive PPC efficiency. Now BR's do win matches but they need some tweeking. However, the PPC for varmints is great, but I would use the BR because it has more down range energy.
I do mostly varmints and informal bench work. I have a 6BR. I sold probably the most accurate rifle I ave ever seen. It was a 6PPC with agg's in the teen's, but brass was a lot of work, was expensive, and very time consuming. The barrel was 19.3 inches and just gorgeous. If you are just going for the ultimate in accuracy PPC, if its multipurpose BR. A lot of benchresters use and PPC for the 100 yard range and switch to the Br for the further distances.
Why I, personally, love the 6BR, I have built and shot every caliber I could think of from 22short to 308 in the varmint range. List includes: 22short, 22lr, 22 mag, 22 hornet, 22 k-hornet, 22ppc, 222, 223, 223ai, 225, 6ppc, 6BR, 243, 6/284, 6rem, 25 rem, 257, 257ai, 260, 264, 7-08, 280, 284, 308. I am sure there are calibers I have missed out on, but these were all the ones I have felt compelled to try, with the exception of the 22BR, which is in the works in the Dasher form. I have done single shots, switch barrels, etc. After narrowing the field down, I tried light weight, super heavy, and everywhere in between. I have tried various barrel lengths as well.
For me there is absolutely NO question. the 6BR, it does everything I want it to do. I have my own reamer and several guns, never been happier. Here's the how and why of my choice. My shooting style consists of bench work from 25-500 yards and sometimes 1000. I usually shoot sub 300. I hunt everything from starlings to whitetail deer. So I sort of needed a gun that would do everything within reason. Here's what I was looking for.
I definitely wanted EXTREME ACCURACY, something easy to reload, extremely efficient, not to bulky if I chose to make a walk around varmint rifle, good bullet selection, great performance on varmints upto yotes at long ranges. The 6BR kept coming up roses. Here's why.
1. Accuracy, second only to the famed 6ppc on the BR circuit, and quit often equal. 2. Velocity, very close to the 243 but with 40% less powder to reload. 3. Throat erosion, as easy on barrels as a 223. 4. You can get 'factory loads' for 1000 yard shooting, so its got the get up and go. 5. Uses a short action. 6. Uses a standard bolt face. 7. Exceptional brass, Lapua and Norma. 8. Low recoil. 9. Low noise. 10. Wide bullet selection, everybody make high quality bullets in a wide assortment of weights. 55g-115g.
As a couple of side notes, as far as knock down power, a friend has taken a 170 pound deer at 400+ yards with one shot, in the head. On varmint hunts, it heats up slowly like a 223, for longer shooting sessions., on the bench there is minimal recoil, I have shot over 100 rounds off the bench and not even developed a flinch.
Just my opinion, good luck
Doc

I agree with Dr Michael's posts. I own about 6 243's. All are real good field shooters, from prairie dogs to deer. Got bigger stuff for bigger critters.

For the guys who do not think a 6mm Remington is a good shooter, I don't know what to say to them except it must be the rifle, not the cartridge.
I have a Remington 700 ADL that was rebarreled to a 24 Stainless Steel PacNor Barrel. It is in a 24 inch sporter weight contour with a 1 in 8 twist, by kevin Wyatt of Medford Oregon. I replaced that factory stock with a laminated Boyds JRS stock. This rifle is a field rifle, not one to have all the "latest" gimmicks. It will shoot anything from 75 grain Hornadys to 107 grain Sierras into one hole groups at 100 yds all day long. And that is with a factory Remington trigger that I have been too lazy to get around adjusting.

For versatility, the 6mm Remington in a Long Action is the way to go for me.

However if it is just straight hardcore one hole shooting group accuracy, I would go with a 6PPC or 6 BR. Ocassionally attending some 600 yd shoots, there is the normal crowd who always places in the top. Almost like a club or clique.
However there is one guy who shows up once in a blue moon that shoots a 6BR. He constantly cleans everyones clocks and goes home.
As for me I would pick the BR over the PPC strictly for the availability and cost of brass, and the BR using the standard .473 bolt face.

As for a prairie dog , I would pick the BR over the 6mm Remington, as it uses less powder, which will heat up the barrel not as quick, result in less throat erosion during high volume shooting ( which I avoid).

Another trick the smaller case will have is if one has learned to use Blue Dot shot gun powder for varmint loads, with a max range of about 250yds for high volume shooting. The smaller case gives good load density, and takes a lot longer to heat up the barrel. It will also have some very consistent velocities when chronographed with an average deviation spread of only 20 fps or so, based off of my experiences with Blue Dot loads in 223s and 22/250s. Accuracy is more than acceptable as minute of prairie dog or less.

I myself have always got a 6mm/223 on my list of need to build rifles. Like the 6BR abd PPC, it is efficient and accurate, and as an extra cheap to shoot.
