Speaking of velocity: I went back thru the loading notes for the .280AI and I am getting 3323 fps with the 120 Nosler BT, just short of 3200 fps with a 139 Hornady, and the first round of loadings (i.e. starting loads) with the 162 AMAX produced 2850 fps from a 23 inch Shilen barrel. This is using H4350, RL 22, and IMR 7828 powder in fireformed RP cases.
Also, these loads are not super hot redline stuff either. I could coax a bit more out if I tried.
I am thinking that duplicating these velocities with a 22 inch 7Mm Remmy shouldn't be too difficult. I can get 3200-3250fps from most 140gr bullets if I use max loads (using the 21.5" barrel).

I really like IMR4831 and R22, and I'm going to start experimenting with IMR7828 and R17.

Personally I wouldn't purchase a 7mm RM at any price. Especially to cut 4 inches of barrel off so it doesn't perfom to the level it should without the extra barrel length. Got buy a 30-06 and you won't be sorry.

Got buy a 30-06 and you won't be sorry. .........Aside from your opinion or dislike of the 7mm RM, the estimated 80 to 120 fps velocity loss from a 4" barrel cut down, won`t make a darns worth of difference in killing power performance on any game one could possibly hunt with a 7mm RM. Long ranges or short ranges, a 22" barreled 7mm RM rifle, will do anything that a 26" barreled 7mm RM can do. That would also apply to just about any other cartridge if the barrel length is reduced.

You truly will get more with a 22" bbled 7mm Rem Mag: blast and kick.
You will also get less: velocity
Don't do it. I'd cut no less than 24", or as others have said, get a .280 or .280 AI or 30-06 or .270.

I either already have or have ready access to a .280 AI, .270, .30/06, .308,.300 Wby, .300 H&H, .340 Wby, .350 RM as well as everything from a .17 Remington to .257 Wby. This 7 Mag is a project designed to fit a special niche (Moderate weight, synthetic stocked rifle)at as low a cost as possible. I am not concerned with pure ballistic performance and I am not looking for a long barreled 9lb plus rifle.

Why are you even bothering to ask questions, since you've already made up your mind about what, why, and how, before you started?

Read fine, think fine, dumb idea. Knock yourself out, my bet is you've not shot one like it. Maybe think about boring it out to 7STW and cut 'er back to 19"...then you'd have a lot more of what you're after, don't need a new barrel, a reamer and hacksaw are all that's required.

Read fine, think fine, dumb idea. Knock yourself out, my bet is you've not shot one like it. Maybe he hasn't, but I have. There is really no difference in blast or kick. Velocity is 100fps or less below the velocities listed in the reloading manuals. The questions is, have you shot a 21 or 22" 7RM?

It'd be akin to everyone who's been laid saying "you'll not like it",which reiterates the reason to consider the source(s).
I'm hip on getting laid and a 22" 7Remmie...in no particular order....................(grin)

Would you then change your mind? It seems to me that most, if not all of the guys that have actually been there and done it don't see a problem with running a 22" 7Mag.
