Trying to decide on what to chamber my rifle with. Pro's cons of each? I was going to get .260 but powder valley was out of stock of uncoated bullets. Made me think of .243. Pros? Cons? The intended use of this will be competition to 1K.

Are you seriously going to choose your chambering based on what bullets powder valley happens to have in stock the day you go to look? Do you feel this is taking the long view?

There's a Berger group buy going on now...

No, not at all. I was just hell bent on .260 and 6.5x47. Just started poking around and reminded myself that the barrel burning .243 was/is an option.

Re: .243 vs .260 vs 6.5x47 Lapua

Have you run them on JBM or somthing side by side? .243 is one of the flattest cartridges out their. IMO my 308 can keep a barrel together forever, it's what I shoot 90+% of the time so I don't really care if my 243 will only last 2K+/-.
 
Re: .243 vs .260 vs 6.5x47 Lapua

Keep drinking the kool-aid to believe what you read about 3K barrel life with a 243.
Know a 243 won't last that long in F-class. Doubt it will make it that long in tactical / sniper use either.
 
Re: .243 vs .260 vs 6.5x47 Lapua

Who gives a shit how long it will last! If a 243 is what you want then get one. You never know, the barrel may last longer than you do! You only live once!!! Enjoy a great cartridge and quite worring about silly shit!

You don't have to "believe" it for it to be true. How many on here have to verify that they have done it for you to believe it?

One thing you can believe is a tactical match is MUCH tougher than an F-Class match.

If you have ever pulled pit for the country's top F-Class shooter, Larry Bartholme, and watched him put 22 shots on paper at 1k in under 4 minutes then you might have a different perspective. These guys are "runners" just like the top BR shooters.

He's nervous about 6.5-284 barrels when they pass the 800 round mark. Run the math on the 6mm Crusader comparing bearing surface and barrel circumference to powder charge and you'll see that it has the potential to be as tough or tougher on the barrel than the 6.5x284.

But hey you guys are the experts.

Re: .243 vs .260 vs 6.5x47 Lapua

I just had a 6.5 x 47 L put on my Stiller Predator and here are some 5-shot 100 yard groups that I shot today I have quite a few groups under 0.5 inch but this may be the best two and I think my load development may be done. I lean towards the 6.5 x 47 Lapua.

Re: .243 vs .260 vs 6.5x47 Lapua

I shot my .243 for about a year and a half in tac matches and won about $10,000 worth of gear. Compared to that a $300 barrel and it isn't a bad trade off. Oh and the barrel is still shooting great with almost 2000 rounds. Also I have shot stages in tac matches where you shoot 20 rounds in 1 minute.

FCS, you might want to talk to Moon who won the 1000 yard Shumway Trophy at the Hide Cup with 3300 rounds of 115 DTACs at about 3100fps down his tube. Barrel burn out figures are exaggerated. Remember when people used to say you wouldn't get more than 1000 rounds through a 300WM? The .243 can make 3000 and then some.

I just started shooting a 6.5 this past year instead of the .243. Only shot 3 matches with my 6.5 Creedmoor so far but up to about $3000 in gear so it's already paid for itself and then some. I like the 6.5 too. Tough decision Smokin.

As to how flat they shoot, the .243 is much flatter at about 7.2 mils to 1000 compared to my 6.5 at about 8.4 mils but inside 600 where a majority of tac match shooting is done, they are really close. Actually wind is what you should look at more than elevation and the .243 only beats the 6.5 Creedmoor by about .3 mils at 1000.

Sorry 9 but 22 rounds in 4 minutes is not impressive at all. As Rob said it's not uncommon to find rapid fire (read less than 1 minute) stages back to back. The movers alone are about 10 rounds in 30 seconds.

barrel life is the price to play. I get 6.5 mils to 1K, I'll shoot it all day, to beat me you'll have to pray, there are no shades of gray, 243 all day, if you don't like it you're gay and you should stay away.

In all seriousness, if the 6mm Crusader gives me <6 mil to 1K, I'll take it and see you at the Nationals.

You can always buy the barrel long (say 27 inches), shoot it till the accuracy starts to fall off, set it back 0.5 inches and shoot another 1.0K to 1.5K rounds. It is almost always due to throat errosion issues. At least that is what I'm headed toward.

Top loads for as much of an apples to apples comparison the .243 will require less drop and windage.

Per JBM:
.243 115 DTAC 3090fps
drop/wind in MOA
300Yd 600Yd 1000YD
-2.9/1.4 -9.8/3.1 -22.7/5.9

.260 140VLD 2850
300Yd 600Yd 1000Yd
-3.7/1.5 -12/3.2 -27.2/6.1

6.5x47 123scenar 2930
300yd 600yd 1000yd
-3.6/1.7 -11.9/3.8 -28/7.2

If you have been getting higher veloctities let me know and I'll plug them in.
 
Re: .243 vs .260 vs 6.5x47 Lapua

I think it also depends on the bullets your shooting, your not gonna get 3000 rounds of VLD's out of a .243 going 3k+, but a jump tolerent bullet like SMK\DTAC no problem, Moly\HBN helps.
 
Re: .243 vs .260 vs 6.5x47 Lapua

Earlier today I packaged up my rifle and dropped it off at UPS. I asked George to make me two .260 barrels. I decided on the caliber so that I could get a bit more barrel life. Now the rhymers have me changing my mind.
 
Re: .243 vs .260 vs 6.5x47 Lapua

243 or 6x47 gets my vote, I'm a 6mm lover though....

Get a barrel with enough shank to have it set back once. Barrels are the cheapest part of this damn sport. As Tom Hines told me (as primers were falling out of their pockets) "There's no point in owning a race car if you're not gonna spin the tires"

Run those Dtacs as hard as you can, replace the barrels as needed, if nothing else you'll keep GAP in business

Re: .243 vs .260 vs 6.5x47 Lapua

All three are pretty awsome cartridges and a tuff choice if choosing just one. You can't really go wrong with any of them and priorities are different for everyone so they all fit the bill in their own way even though they are really close performance wise.
 
Re: .243 vs .260 vs 6.5x47 Lapua

Anyone know the BC on the 115 DTAC? I ran some ballistics on 139 Scenars vs 115 VLD's and the 139 Scenars at 2850 seems to out perform (for wind) the 114 VLD's running at 3100 at 1K yards

We're not going to throw the 7wsm in the mix. Although it is an awesome chambering, it does not belong in this conversation. We'll reserve that for another thread.

+1
the 7's can be absolutely awsome. Although ballistically the 7mm shortmags and .243 (again in as much apples to apples chamberings) are nearly twins the 7's hit much much harder. I think the 7mm shortmags are tuff to beat as an all around cartidge for LR, hunting, matches etc.

Re: .243 vs .260 vs 6.5x47 Lapua

Thanks for proving my point. Been there, done that with 243 and have plenty of data to know it will not hold up for 3K rounds in F-class.

I've got some hot 6mm chambered rifles but I sure as hell wouldn't lead someone to believe he'll get 3k rounds out of a barrel.
 
Re: .243 vs .260 vs 6.5x47 Lapua

Rob, appreciate the suggestion of asking for advice but I've gathered plenty of my own data. Paper doesn't lie at 1K. I've shot both tactical and F-class, F-class target at 1K (if you want to be competitive at National level) is bit tougher than hitting a LaRue at 1K.
 
Re: .243 vs .260 vs 6.5x47 Lapua

243, 243AI, 6mm, 6mmAI, 6mm Crusader - all great rounds, lots of fun, and really flat. I don't get attached to barrels, they wear out. I migrated more to F-class than tactical so finding a caliber at knee of the curve, get me a whole season w/o going to Nationals with wore out barrel or new, unproven barrel is my goal.

Depends on use and goals but in a competition setting, very unlikely you are going to be competitive (in F-class anyways) with a hot 6mm at anything over 1500 rounds and 1100 is closer to truth.

Want a hot 6mm? Get one and have fun with it. Just don't be suprised when the barrel gives it up a long ways before you get to 3K rds down the tube.
 
Re: .243 vs .260 vs 6.5x47 Lapua

Truth be known FCS, we'll be able to put your theory to the test. I currently have around 1K rounds on my 243 right now. By the time the CUP is over, I'll have close to 1500 with practice and match. I plan on shooting F-Class over the spring and summer. We'll see if she holds up past 1500. I'll post my scores.
