700 yard groundhogs 243 vs 260

which caliber would be better, I'm torn between the two. I have seen this topic posted plenty times before, but over 3/4 of the comments are a suggestion of different calibers, and then a debate between two or three calibers that people threw in the posts. I am buying a factory rifle because I can't afford a custom rifle at the moment, and these are the two caliber offered, so a suggestion of a different caliber is not an option. I live in ohio, which is a slug gun only state as far as deer go, so this will be strictly a varmint/recreational target shooting rifle. I know the 243 is capable of flatter trajectories, with the lighter bullets, but the 260 usually has a higher bc on the 100+ gr bullets. how does wind play with the two calibers with 75-87 gr in the 243, and 95gr in the 260. the 243 has the option of 58 gr. bullets for some real splatter power which is tempting, but I handload a 110 gr hp in 30-06 for that.

What twist rates can you get in the factory barrels ? That will be a big decider, since I don't know of a factory 243 with a 1:8 twist. With a 1:9 or 1:9.25 twist barrel you can forget about shooting 95gr or 105gr VLD's with any accuracy. If you can get a 260 with a 1:8 barrel from a factory you might be better off. Otherwise get a short action savage and put a good quality 26" 1:8 prefit on for $320 and go shooting.

I would like to start by welcoming you to the site first before we get to business!

Now for the business, I have a Remington 700 ADL Varmint chambered in .243 Winchester and absolutely love it. It has a 1-9 1/8 twist that stabilizes 87gr V-MAXs amazingly well. It shoots one hole groups and is well under MOA at 700yds where my range card ends. For wind, that little 87 grainer bucks it well going 3250 at the muzzle with a BC of .400 and it also blows stuff up so its the best of both worlds. This deadly versatility is what led me to buy a .243 for all around varminting from 0-700yds. I have no desire to shoot big VLDs in it because its a varmint rifle so a high speed, explosive bullet with a good BC like the 87gr V-MAX fits the bill perfect for me. No other bullet caliber overs such a great varmint bullet as the 87gr V-MAX, it does it all, high BC, accurate, fast, explosive just perfect. This is why I consider the .243 Winchester matched with 87 grainers the most effective all around varmint getter.

Savage rifles chambered in 260 come with a 1-8 twist. I have the predator hunter max 1. Its a very nice shooting rifle. My hand loads are under .5 moa.

Re: 700 yard groundhogs 243 vs 260

Greg,
Welcome to Long Range Hunting. I've owned both calibers but have only used the .243 in a varmint role. It performs better, the farther out you go, with heavier bullets. I started low (58gn) and ended up shooting the 95gn Ballistic Tip. Shots out to 6-700yds are doable (for me) with this setup. Didn't have a chance to shoot much further.
The .260 I had in a Remington Mountain Rifle and it was strictly used on deer. With 120gn Ballistic Tips, it did its job well. As a heavy barreled varmint round it would/will do anything the .243 can do and probably a little more. If you get a 1-9 twist you'll probably be limited to the 120gn, with a 1-8 twist you can shoot the 140's.
Yeah, the light pills are fast and impressive, but they peter out quick and can't stay the course in the wind. Regardless of the caliber, get a fast twist barrel and launch the heavies at 'em. Happy hunting. JohnnyK.

Re: 700 yard groundhogs 243 vs 260

Thanks for the input guys. I've decided on the .243 after some suggestions and from searching midwayusa and other sites seeing how there is a much larger bullet selection for the 6mm over the 6.5. unfortunately as jud pointed out, I am buying a savage model 12 lrp, and it offers both the 243 and 260 only with 9.25 twist rates, but the 87gr v max as mentioned in the replies has a .4 bc, and should stabilize well in that twist rate barrel. the rifle is also offered in 6.5 cm with a 1-8 twist, but it seems to me that the 260 shoots the heavier high bc bullets a bit faster, meaning a bit flatter. since a woodchuck isn't a steel plate at a known distance, I'd opt for a flatter shooting round.
