I do when my 15 year old son now steals my 25.06 and leaves me with only a .280AI cannon to lug around the woods! I need a nice little compact 7mm to see me into old age!
I've now had another thought though.............
should I get a 7mm 08 AI ??

You've got a thing for AI! Looked at it a while ago for mine but the improvement really wasn't going to make that much of a difference.
A friend uses a 7mm-08 with an 18* barrel and have some info somewhere using 120gr Pro Hunters and they work - just got to find the load details. Will give you a call.

I nearly called you earlier but ran out of day! Would be good to catch up again!

A few years ago, Remington made the Model 7 in a nice walnut stock with fore end cap, like the Mountain Rifle, and with iron sights and a 20-inch barrel. They made one batch, a few hundred each of .223, .243, 7mm-08, and .308 Win. They sold like hot cakes, and the marketing brainiacs never made any more of them.

So it's your son who needs a new rifle then? Perhaps you should take him to a gun shop to try a few for size?

For that I would rather go with the 6.5x47
Hi M.S.
My Savage 7mm-08 had a 19" barrel and shot great, I have ordered a 7mm-08 barrel for my RWS Titan. Should be here in a couple of weeks. I think I will go to 20" for this one.

RPA do their Woodland Stalker rifle in both .243 and .308 with only a 16" Barrel!

7mm in the same case can't be too different surely?
MS
.243 and 7mm-08 have the same case volume as their parent case, the .308 Win, but to have the same ratio of bore volume, the 7mm-08 requres 18% more barrel length.
.308 / 18 inch equates to 7mm-08 / 21 inches.
Gas pressure is linear with the volume change, although the pressure curves may not be exactly the same, but they will be close, with the same powder and bullet weight. That is why the 150 bullet that works well in the .308 carbine of 20 inches, and the 140-gr bullet will work about the same in the 7mm-08 20-inch carbine.

Mind boggling stuff and much appreciated! It would appear that a 308 works well in 16" barrel. What would you suggest is the absolute minimum length for a moderated 7 08 then? I've just been sent pictures of a very impressive group from a 7 08 in a 18" barrel.
MS
Just done some maths!
18% 0f 16 = 2.88
16 + 2.88 = 18.88
So maybe a 19" barrel would be sweet?

I have no experience with moderators on 7mm anything, but I suspect 19 inches is a good length, but why not just go 20, since it is a common length in factory rifles, so a known entity.
As I stated in my first reply, I think 20 inches is my minimum, and I own a Model 70 Compact and a Browning BLR with 20-inch barrels which work well. And my Tikka T3, with a 22.5 inch barrel, seems to get most of the goody out of the cartridge.
I also own 7x64s with 20-inch and 23.5 inch, and the MV velocity difference is more pronounced.

My 7mm-08 with 19" barrel was used un-moderated mainly for Fallow.
I found Barnes TTSX 140 gr at 50 thou off with BLC-2 was really sweet it left a decent wound channel with a good exit without lots of damage.
I don't know about the mind boggling statistics but on Fallow and Muntie it was lethal and that's why I've ordered another 7mm-08 and will have it cut to 20".

308 works well in the 16" barrel DTA Covert has that and is rated to 750yrds was at bisley Sat and a guy had one was struggling a bit at 900 and 1000 but was factory ammo still not to bad wind was pretty blowy as well
Im hoping to build a short light weight Deer gun (as my first
) in 6.5 x 47mm maybe 260 rem cant decide on 16 or 18 " at the moment
but
MAE does the Shorty in 6.5x47 with a 14" barrel just meets the min ME so was going to go a little up on that 65x47 Lapua Shorty - MAE Moderators UK
considering how short range Stalking (as every body keeps saying on here) is it shouldn't need much

A shooting buddy of mine has the 19" Steyr scout in 7-08, he is extremely happy with his as it is very accurate and the cartridge works very well. He replaced a 270 win and wsm with this rifle.
NZ Hunter magazine had some load data a few years ago of 16" 308 and 7-08. They achieved a max of around 3000fps with 120gr ttsx or tsx out of the 7-08 with h335. The 308 achieved the same with the same powder and a 130gr tsx/ttsx.

I think you're missing the point slightly here as you have no experience with moderators. A 20" barrel is clearly a known entity, but with a 4" moderator on the end it is a 24" entity which is a bit too long for a compact woodland stalking rifle and hence my original question.
MS
Yes, I get that. The suppessors I have used were larger than that, and on an M-14 - unwieldy.
But if you are in the woods and shots are short ( under 150 yards ), put it on an 18-inch barrel.
I have several .308s ( military ) which have barrels of 17.5 inches plus 3/4 inch of flash hider. And I have taken deer with them, and wild boar - worked fine.
But the same gas pressure will act on more bullet base area, exert more force, and yield higher velocity with the same weight bullet than a 7mm. But 10 grains or 100 fps makes no real difference.

I have owned about 150 CF rifles from .223 to .458WM in the past 50 years and currently have 35, including ONE full custom Remmy 7 STS ultralight "sheep shooter" in 7-08which has ALL the goodies and weighs 6-4 scoped with Talley base. QD steel rings and Leupy VX2 2x7. I have not handloaded for it as yet, but, have loaded since Jan. 1968 and for many cartridges.
I live and hunt in BC-Canada, so, hunt some of the thickest bush anywhere and our seasons for Moose, Elk, deer and other game overlap, so I prefer a heavier bullet and a controlled expansion type for all my uses.
I use Federal Fusion 140s, will load as I have and do with my 7x57 rifles, the 140 NP at about 2800+ from the 22" barrel. I worked in resource management for years, packing a Grizzly defence gun all day-every day in dense bush and have used barrels from 16.5 to 27" all over BC. I prefer 23" tubes on my custom rifles, but, 22" is fine for 7-08 and .308Win. rifles as my STS customs in these chamberings wear.
IF, and I have hunted highseat here in the coastal jungle, I wanted a rifle for ONLY such uses, I would get a .308 not a 7-08 and a tube NO less than 20" and this has worked well for me. IF, it was to be a 7-08, a 22" is my minimum and also does just fine on treestands....I often use my pair of Dakota 76-.338WM rifles with 23" bbls.on my treestand, no big issue, it works well.
For the OP, how about the new Kimber 84M Adirondack with it's 18" tube, STS, synthetic and light, seems ideal for your wishes.
