Good brass and H4350 is a 260s friend. 4350/130AB did 1/2 MOA at 200yds in a 9 twist Sako, twice...spun 139-142 well under MOA. OTOH a custom 6.5-308 I had built before the 260 was SAAMI did not like 140 PT. It came in 9 but ordered 8.
8 twist preferred, Ruger did them, now Creedmoor is the newer kid on the block Also in 8t. Can't argue success but a good 6.5 rates high and I've shot my share of accurate 6, 6.5, and 7s. All will work.

I took my Axis Deer this year with a TC Icon in 6.5 Creedmoor. It has a 1 in 8 twist and I shoot 140 gr bullets at 2800 FPS. This round may be "the newer kid on the block" but I like it better than any other 6.5 caliber I ever had (I've had 6.5x284, 6.5x47 Lapua and 260). It is easy to tune and, with low recoil, is a great choice for hunting or match shooting.
I'm shoot4fun on Accurate Shooter Forum and you can see my feedback there.

Overbore is really the wrong word, i should have said faster cartridges.

What's wrong with a 600 Rem in 350 Mag all r 18" barrels, will kill anything out to About 300 yd.s if you can shoot!

Interesting thoughts - thanks. As an update on Black Friday I picked up a Rem 700 ADL youth model (20" Barrel) in .243. I'm hoping that it will make for a poor man's mountain rifle. Early testing has proved it to be about a 1" @ 100 yds gun with a few groups better and a few around 1.5". I need to do some experimenting with floating the barrel and some different reloading. It tends to string shots horizontally when it gets hot - certainly deer accurate, but not yet varmint accurate. I think this gun will do a nice job filling a pretty big void between my .22lr and 30-06.

I prefer classic. Semper Fi I used to run with the hare. Now I'm envious of the tortoise and I do my own stunts but rarely intentionally

A really nice stock for that one is a ti takeoff (stockys 2950 bell and carlson) englarge the barrel channel and you will have a nicely balanced and light handy rig. For reference my 24" LA 700 adl with that stock and 6x42 weighs in at 7.5# on the nose. The exact weight of my dads 20" (smaller barrel contour) model 7 with a 2-7 leupold. Those factory plastic stocks are heavy!

.308 is a caliber. 7mm/08 & 243 are not. If .308 is a caliber, so is .243.

The larger bore to case volume ratio the better for short barrels. The larger diameter bullets in the same case size will normally have faster burning powders and thus more complete combustion.
In this case size the most efficient short barreled rifle would be in progression - 358 Win, 338 Federal, 308 Win, 7mm-08 Rem, 6.5mm (260 Rem), 6mm (243 Win).

I've run all 3 in 20" guns and 2 in 18.5" tubes, all shoot and kill fine. I agree with many that the velocity loss is less than you think. I do like the 7-08 the best but all 3 will do and then throw in the 260, 338 fed and 358 win and the choices are many, heck go all the way and build a 25-08, that would fit the bill for your intended quarry

Don;t overlook the 280 AI.
I am playing with one with a 22" barrel and the velocities are not far away from Noslers, which were achieved with 26" barrel length.

.308 for deer; 9.3X62 for anything bigger.

For deer, coyote, chuck I'd go .243 without the slightest hesitation. If .223 was on the list I'd have to flip a coin to choose between it and the .243. The .308 and 7-08 wouldn't be in the running. I'm in this camp.

If nothing larger than deer, get a 243. He11 get a 223. I was in this camp also. But apparently, for deer/coyote/chucks, the .358 Win. is the correct answer. Not opinion, but soundly verified as fact. Followed closely by by the 9.3x62 with the 280AI nipping at it's heels......

Yeah, going real short will show the 308 winning the competition since it has to do with expansion ratio. But at 20, I would say either the .308 or the 7mm would work fine. Now, if you want to go real short, go with a .35 caliber! Check this out as reference from Lyman: Chuck Hawks ref; Lyman Manual scroll to the bottom about velocity loss / inch of barrel. The old .35 Remington wins out. That is why it was one of the original chamberings in the T/C Contenders.
Better to be judged by 12 than carried by six.

centershot 20 fps per inch of barrel, regardless of caliber or powder. A 223 or a 300 Ultra mag gains or losses about 20 fps per inch of barrel. If I were good with the search feature, I'd find the test I posted several years back. Charlie
