May I ask why you are limiting yourself to 20" ? Having an extra 4-6" is every bit as important to shooting as it is to my wife!
308 or 30-06 with heavy’s

Cut down the 308. Use a partition. Or try the hammer hunters. Should be real flat inside 300, and not much drop at 400.

An extra 6"? Good Lord, you know too much and she'll taste what soap you're using.

Back to the original posted question...
I would be possibly concerned about heavy bullet stability in the suppressor with the shorter barrel. I would personally lean to shortening the '06 since more powder capacity would open the option of more powder and velocity to regain bullet stability. As stated by others, check bullet stability BEFORE screwing that suppressor on. Good luck and please update later with your decision and results. I am perfectly willing to learn from others mistakes and triumphs rather than have to repeat them for myself, which after all is one of the great info sharing benefits of forums. Thank you for sharing.

Gee. Even with a .308 Winchester, 24-inch barrel and 180s yer only gonna get 2600-fps.
And what are we hunting? - How far?
And .30-06 with same barrel length (24), and bullet (180) = 2800-fps

Shoot what you want,but I really like long barrels.At the present time I have one 308 and four 30-06's.I know there are fast and slow barrels at
any given length.But here's how mine do with a 168gr Nosler Ballistic Tip.My 26" barrel 308 did really well with TAC and Accurate 4064.A little better than 2800fps,.My Varget load runs about 2700fps.My 22"barrel 30-06 struggles to get around 2800fps.My two 24" barreled 30-06's max out around 2900fps and my 28" barreled 30-06 can easily do around 3030fps ave.

2630 fps with 180 Nosler BTs @ 18" barrel length (Rock Creek) using RL 16. At 105% of book value I was getting just over 2700 fps with that powder/bullet combo. I chose a lower velocity in favor of accuracy.
For reference, I can just get over 2600 fps out of a Rock Creek barreled 308 @ 20" using 180 Hornady SSTs and Varget. So 2 more inches of barrel and ~ maybe 30-100 fps less velocity.
I haven't put both rifles next to each other, but I think they're likely the same overall length.
I have no doubt that you can push a 200gr projectile to 2600 fps out of a 20" barrel. Be not afraid. It's a fun rifle when its done.

And that how I roll. 2850 fps with 215 berger and RL26 is nothing sneeze at. Not for a old "outdated" non magnum.
Wow. 90% of the velocity with 2/3 of the powder. Some cartridge!Gee. Even with a .308 Winchester, 24-inch barrel and 180s yer only gonna get 2600-fps.

If I pushed it with CFE223 or something even slower, I could probably hit within 100 FPS with a 215 in the .308 Win.

The smaller capacity cartridges are more efficient for sure. You pay to play with the larger capacity cartridges, more speed and powder leads to less barrel life. A properly setup 300 win mag will definitely push the 215 over 2850 fps. I have a 308, used to have a 30-06 (didn't really do it for me) and two win mags. I shoot the 215's out of one of my win mags and settled on a accuracy node a few fps shy of 3000 but got over 3060 before I saw pressure signs.

Yeah, a lot of people still think of it as "grandpa's old deer rifle", and think that the .308 Win is a slow outdated. But with modern brass, bullets, powder, and barrels, the .308 Win is just as capable as any "modern" cartridge we have today.
