So I want to do a build on a Remington 700 set up. I am having a real hard time deciding between these two excellent choices. I plan to run either one in factory trim. Meaning I'm not really sure I want to "wildcat" them.
These are the bullet choices I have narrowed down to in each caliber.

243 using 107gr. SMK.
or
260 using 142gr. SMK.
 
If it was me, I would pick the 260 only because the barrel life is better. Now that you can get brass from Lapua in 260 it makes the decision easier.

Both are great choices however.
 
Higher BC bullets available for the .260 for long range work.

Nothing wrong with .243 , the .260 just has a bit of an edge when it comes to "ease of use" at streching it's legs. Easy to load for with tons of info out there for it.

p.s. I see that you wanna shoot past 500 yards in Sask, very ironic that the flattest spot in Canada had the fewest long range facilities available.:confused:

Good thing most of us know rural land owners.
 
I wouldn't do a 243 as a target round period. If I were looking for a super accurate high-power 6mm, I would go 6 SLR (based on the 243) or 6XC, otherwise a 6BR - no question. That round is so efficient and so accurate it makes a big 6 appealing only for use with 115 and heavier bullets exclusively.

Alternatively, the 260 is a damned fine cartridge.

Should be easy to get either of those bullets to shoot well. SMKs are great that way... I would be using the 115 DTAC though. Mystic can get them.

Thanks for that super informative link. Fantastic and helpful reading. Nice to know that the 155 gr Lapua Scenars (bought from Peter Dobson, Hirsch Precision) are the way to go for the .308.

I still have a hankering for the .260 Rem project in my M700 SA build sometime this year. I can still dream! ;)

Cheers,

Easy choice. Barrel life is better with the 6.5 mm, and down range ballistics are better if you get a 1 in 8" twist to shoot the 140 and 142 grain low drag bullets.

Hi. If you're thinking hunting, neither bullet is a hunting bullet. Just as neither cartridge is that great for pure target shooting. However, and as much as I like my .243, for large game hunting, the .260 is more versatile.
On the hand, the biggest advantage of the .243 is its widespread availability. It'll be found anywhere, the .260 might not be easily found in small places. The .243 is not a barrel burner either.

According to this the standard .260 is just begging to use the Berger 130gr. You should be able to drive it more than the 6.5x47 and it has better BC than the 142gr MK. Don't know if that are actual figures in real downrange results.

The 142 Sierra has (According to Litz's book anyway...) a G1BC of .588 and a G7 of .301

The 130 Berger has a GIBC of .552 and G7 is .282 so the numbers favour the Sierra.

I have shot the 142 Sierras and 140 Bergers out of a 260, and I am here to tell you the 140 berger is stellar. Its .612 BC is so good that minor differences in velocity do not mean much. It is a true 1000 yard contender.

That's why I'm a bit perplexed that the author claims a slightly higher BC and less wind drift with 130gr berger driven by 6.5x47 than a 142gr MK driven by the .260. Unless I'm reading it wrong.

I agree the Berger 140gr has a slight edge over the 142gr MK. I can bear that out from experience.
 
i don't have time to fully research but just planting the thought. i could probaly get 75fps more witht the 130 berger which would put me over the 3000 threshold. now a berger traveling at 3031 fps or close to might just beat my 140 sierra. now you see im to cheap to attempt to figure out. oh ya pick the 260 it is great 243 is DEAD NOW THAT THE 260 is catching on
 
243 vs 260 comparison - are you kidding ?

These are 2 ridiculous and unfair comparisons....not in same league
the follwoing are more realistic comparisons...
223 vs. 22-250 vs 204
243 vs. 6mm vs 243Ackley
260 vs 308 vs 6.5-284

It's very easy to pee on the innocent 243
What are you really giving up whilst reloading the finicky 260 calibre.
308 is supperior in every dept. and offers the longest barrel life, if you want that....
6.5-284 is the superior 6.5 long range calibre, if you want that...

It's only yesterday that LAPUA has saved the 260's life, for now.
It's a marginal calibre for big game, long range, or accuracy acclaims.

No 155 gr. bullet has a higher BC than the 155 Scenar once it's pointed. The Berger 155.5 Fullbore beats it by a hair out of the box, but it already has a tiny meplat. The meplat on the Scenar is huge, and you gain many points from pointing it.

That being said, I tend to prefer non-VLD bullets since you don't have to chase the lands with them. That's a really good thing with a throat burner...

Obtunded, where can I get a reamer for the 6 SLR? I don't see one at Pacific Tool.
