Which caliber would be better in 22" or below? I would like to achieve 2700fps with a 140gr bullet. How short can I go? Allready have a 26" long and heavy and wanting something more handy

My 20" 260 averages a tick over 2700fps with 140gr HPBT and 43.0gr H4350; a similar charge of RL17 should be good for another 50+ fps.
I have a 21.5" 6.5 creedmoor that shoots the 140 Amax at about 2775 with no pressure signs. I would think either would do it.
I have been looking for similar answers, but this was the most reasonable article I could find: Follow Up Short Barrel 6.5mm Rifle | Sin City Precision .
If 2800fps with a 123g Scenar can be done with a 16.5" 6.5 Creed, I would imagine similar results seen with a x47 or 260. With a shorter barrel, projectiles around the 120-123g range seem to be the most viable option.
That said, I would also be interested to hear 136g Scenar-L and 140g Hybrid results with confirmed velocity data.

Thanks for the info guys! Keep it comin
Look no further, 16.5" 6.5x47L... Velocity of 136 gr. scenars, 130 gr. bergers & 100 gr. scenars published in thread.

My former 18.5" 260 did 2,700 fps with my 139gr Lapau handloads as did the Black Hills factory ammo with the same bullet.
22.5" 6.5CM with 140 Amax @ 2.810" over 43.5gr H4350 gave me 3300+ rounds of 2820fps on my last barrel.
The 6.5x47 is down on functional capacity about 10% compared to the 6.5CM and 260 Rem, it's at a disadvantage in this case.

I currently shot out a 6.5 creedmoor surgeon just yesterday and sent it off today for rebarrel to a x47.. my dad shoots a 260 surgeon..Im stuck on having to have lapua brass. Im building a whole new set up for more of a handy rifle for sure in 260 or x47. My old creedmoor will be a 25" x47 so I want something a lot different on the new build since I already have the long unhandy version lol
Good info. I have the urge to chop my 24" 260 down to 20". The extra 8" of suppressor is kind of a pain sometimes.
In my 20" .260 with a Brux 8.5" twist, I am getting 2755fps with 140 amax and 2850fps with 130 accubonds. Both loads are with H4350, Norma brass and Rem 9.5 primers. Seated to max AI mag length. I am generally shooting at around 275' asl.
Thanks for info guys!!
My buddy Chubbles shoots a 21.5" or 22" (cant remember) X47, we've had no trouble getting 2800+ with 140's and 40-ish grains of H4350.
