Hey guys,
I've got the itch for a new varmint rifle. I have several .22, .17 and .223 and was thinking of 6mm/.243. I also have a 7mm rem custom that I don't use and could be a possibility for a rebarrel. Any thoughts or suggestions?

Thanks,

Jeff

The 6mm's gained a leg up on the 224's what with the new 55 and 58 gr bullets that perform just like they were maxed out Swifts.

That's reason enough to get a 6mm.

As for long range it's sort of a "theory of relativity". When the range gets bigger the cartridge should get bigger.

Jeff,
I'd seriously consider a 6m/m Dasher if I were you. This little darlin' presently owns the 1,000yd. benchrest record, spanking the 30 caliber Magnum fraternity in the process. The mans name is Richard Schatz(see his interview). On his way to setting the record, he shot a 5 shot group that measured 4" flat and his 6 target Agg.(30 shots)was 6,125" You can find out all you need to know at 6mmBR.com Another plus, Lapua makes brass for the parent cartridge. This should help narrow your search.

stepchild 2,

Thanks for the insight. I am not famaliar with the 6mm Dasher but will research it at the listed site.

Thanks,

Jeff

Wasn't his record in the light gun. He shot a 11 lb rifle 6lbs less than most light rifle shooter and the caliber are normally lighter than the heavy. I think the agg for light and heavy rifle is around 5.9" and the record for the heavy rifle about 5.1" shame that 6 Dasher cann't spanke those 30cal in the heavy. Over the last few years the 6 dasher has done pretty well winning here and there be interesting to see what happens this coming summer to that record.

I've got a 6mm Rem AI that is an awesome long range varmit rifle. I tend to use it a little while the rifles cool or when the wind picks up. Nothing like drilling them at over 400 yards. What size is the bolt face or your action? It can also double as a 1000yd gun depending on the twist. I went with the 1-14 twist for the varmits and it shoots the 87gr w/ 1/2 MOA. Its on a Rem 700 trued w/ Max HV Hart Barrel. What size is the bolt face or your action?

I think fewer and fewer companies are producing the 6mm Rem. at this time. Originally it was called the .244Remigton but the twist was such that it wouldn't stabilize the 100gr. bullet. Winchester came out with almost the same
caliber, the .243Win., with a 1 in 10" barrel twist, advertised it as a deer/varmint rifle and never looked back. Remington renamed theirs to the 6mm Rem. but never caught up with the .243Win. I have both calibers and see little difference between them. Best wishes.

Cal Sibley is correct--the .243 Win and the .244 Rem both came out 1955 and Remington didnt correct the twist problem until 1963 when they merely changed twist and renamed it the 6MM Rem. The 6MM Rem does have a little velocity over the .243 but not earth shattering. Had the twist been the same in 1955 when they came out,would be interesting which of the two would have the greater popularity today but with an 8 year head start the .243 remains in front.

I wouldn't worry about whether the factories had a 6mm Rem out or not. I personally would just get a rifle rebarreled for specialized target work or long range varmint shooting.

I own about 6 different 243s, and only ONE 6mm Remington. ON that one, I put it on a long action Model 700, with it long throated and a heavy sporter with a 1 in 7 twist for the 107 and 115 grain match bullets. Having had access to a 6mm/06 AI to compare it to my 6mm Remington also gave some insight.

A long action based 6mm Remington has it all over a short action 243. It also does not give up a lot to the 6mm/06 AI if anything at all. Same goes for a 240 Weatherby.

So Remingtons marketing dept muffed the launch of the 244/6mmRem. Whoever put the 6mm bullet on a 57mm case with a long neck on a long action with a long throat, sure had their act together on efficiency and performance.

I have another 6mm Rem barrel in the works on a Mauser action with a 1 in 14 twist this time. It will be dedicated to bullet weights of 75 grains and under, in a bull barrel configuration for prairie dogs and just high velocity varmint bullets.

NO Factory is going to build a gun like that for the masses, and if they did, I am sure the price would be to the point that few would be sold.

The 243 is perfect for the crowd that their major supplier is Walmart for all their hunting and shooting needs. The 6mm Rem is for the guys that get off the beaten path, and want a lot more performance. A $400.00 rebarrel job and you are off to the races with a gun that would have cost you a lot more to get an equal that came out of a "factory".

I just recently finished my 6mm project. I had Mark Penrod fit a shilen #5 at 25'' to a short 700 then I put it in a Mcmillan sporter. I am very pleased with the rifle. It is used almost exclusively as a coyote rifle with 70 NBT and IMR 4350. I'm going to try 55 NBTs. I have a little sewing to do but it knocks them right down at any sane range. If I had to do it over again I probably would have used a #4 tube. The 6mm rem is great, if you reload.

How about a 6/284 ??

Tom,
Yes, his rifle is 5 or 6 pounds under the class limit, purposely built so he can compete in different(sanctions) matches, rather than have several rifles.
A 4" group at 1,000yds is impressive regardless of caliber, at least to me.
Who knows what summer will bring, but right now he's a happy camper.

I agree whole heartedly. I own a very accurate 6mm Rem built on a Rem '03-A3 action, 26" heavy barrel, 1-10 twist. If you handload, pass the .243 Win and all the other "benchrest" cartridges and get a 6mm Rem.

My step dad bought this rifle in the sixties from a guy who had it made. He blessed me with it about 10 years ago.

The first time I shot this rifle was at 125 yards, it was the day my step-dad gave it to me. I thought I missed the target with the second shot. My step-dad told me to "lay the rifle down and let's go for a walk."

There was one hole in the target with a very slight crescent where the second round hit. This rifle will do this out to about 300 yards. At 400 yards it "opens up" to a cloverleaf. This is typical for the cartridge in a good quality rifle.

Leave the 22's behind, get a 6mm.

Correct, however with a 1-14 twist of the 6mm Rem you can push the velocity of sub-70 grain bullets without the problem up over-stabilization, or bullet blow-up. It has about a 200-300 fps advantage over the .243 Win weight to weight.

If you are building a 6mm Rem for varmints exclusively, I would go with the 1-14 twist, or maybe 1-10. The 6mm is factory at 1-9 and it tends to be more than you need for 55-70 grain bullets when you push them.

I use Sierra 55 and 60 grain HP's. They are very consistent box to box. Some other brands have not shown this consisitency. I push them about 3500 FPS which seems to show the best accuracy in my rifle.

I have a 6mm in a Remmington 788 and have owned it for 35 years. I do use it for prairie dogs and for other varmits. Its a great caliber and very accurate and you have a wide selection of bullets to choose from. I also have 223 and 22-250, but my go to gun is the 6mm. Steve 48

Flippy--What's your point? Are you saying the 200-300 fps is earth shattering?

I just wanted to revive this, the 6mmBR (NORMA) uses a slightly different reamer than theBR remington wich both are different than the normal 6mm remington. The 6mm BR (norma) and 6mm Dasher(improved BR)use a small rifle primer pocket and the pressure and burn ratio of the case are better suited to ballistics and accuracy. the Dasher can achieve very close to the same velocity and MUCH better accuracy than the 6mm remington thats why its so popular in the BR world and nobody uses the 6mm remi. Its an awesome varmint,BR or deer cartridge and the regular BR(Norma)is just as good inside 600 yds.

Is your 7mm Rem a 7mm magnum?

If so, you are looking at replacing the bolt. If it's a 7x57 then it's less work.

Agree on the Dasher. It is GOOD.
I've been collecting Rem 722's and bought a 722 in 244 from one of the posters here on AR. It's a "B" grade, and beautiful. It shoots extremely well too. If you reload, any chambering is doable, so the Dasher would be my first pick.
But, I had no trouble finding brass for the 244, and dies are readily available too.
I like the case design of the 244 over the 243, but that's just me.

Lovely cartridge. Only ever used it for deer but it is lovely. The best way to get a 6mm in a mauser

Go with the 6mm Norma in a Savage rblp LRPV.

Watch the twist and velocity with the 6mm.. Its a wide range use caliber.. Good for super fast small bullets and blowemup, or long range, but not both.. If you want long range you need 3000fps (aprox depending on balistic coeficeint) and 1-9 or faster for 1000 yards with aprox .400 balistic coeficcient.. the 87 gr vmax will do it if you can get it to shoot accurately, 1/2 inch moa is good enough.... The speed is necesary to retain supersonic velocity at 1000 yards.. Also know that the 6mmbr is not a good repeater cartridge becouse of the case shape(so a gunsmith told me), dont know about the rest.. its kind of interesting the 6mm rem in a rem 788 rifle (if it will shoot well) at 3000 or over is a great 1000 yard gun with about 8 lbs added weight forward.. with a good harris bipod sinched down tight enough so you wont change cant on firing prone , and it hold it down to view impact and reload easily to shoot followup shot.. The weight is also necesary to keep the non trigger hand off the front of the gun and on the rear bag quickly fine tooning your next shot.... And its a repeater so with a good scope with rear bag, you can march the impacts in on a properly placed target (that has visible impacts) using a good scope to compensate for a prevailing wind alowing simular deflection with multiple shots.... Breaking one or more of these rules is why some calibers or rifles are called 600 yard guns even tho extreemly accurate, and why evey one belives its so hard to shoot 1000 yards, unless you have a gun that blows your ears out and kicks the crap out of you.. . dave

Do you guys realizing you are responding to someone who posted this THREE years ago?

you boys ought to look at the dates on some of these posts....

just a suggestion..

Too funny. Seafire, I see this happen often. I have even fell for it once or twice.
