SA vs LA Rem 700 differences

In the Rem 700 SA, is it the receiver opening or the mag length which limits cartridge selection? I'm interested in a 6.5 something. I want to easily hit 2900-2950 fps with 140 gr bullets from a 26" barrel. I want more than 260 Rem/260 AI. I've considered the 6.5 WSM but shy away from the FAT idea; not the theory, but the limitation on mag capacity of 2 rounds. Is it possible to use a 6.5x55 or 6.5x57 in the SA or do they need the LA? Might the 8mm Mauser case give a slight capacity advantage since the shoulder is a skootch longer than the 7mm?

In a Rem 700 the receiver opening and the magazine are the same length.

Both the 6.5 x 55mm and the 6.5 x 57mm will work in the short action. After all, the M700 was and still is chambered for the 6mm Remington which is 57mm long.

If you load your bullets out to exceed factory OAL you may not be able to eject a loaded round without removing the bolt but that is a minor inconvenience.

Although limiting in magazine capacity, the 6.5x.284 is available with factory brass. This is an exceptionally fine cartridge (and I do own a 6.5WSM) equal to the .280 Rem.
Now I have a question. Do you really think you will need more than two cartridges in the magazine and one in the chamber? While hunting, I've never seen that need and am happy with my 2+1 gun.

It just occured to me that what you call the "receiver opening" is what I call the loading port or ejection port. In a short action it (loading port) is about 1/2" shorter than the magazine. But all of my other comments still apply.

Ray,

Ya know, your right. I took a peek at my Cartridges of the World and the 6mm, 257 Rob and 7mm Mauser are all with in .003 of each other. I just want to make sure that the 140's don't eat up powder space if seated to factory OAL and remain as a repeater.

Prof242,

Do do have a point. Though I do prefer to leave the chamber empty until just before the moment of truth, then I simply slip one in the chamber. In a quick response senario, I'd only have two up quick. Course, if I do my part, that's all I need.

And anyone who has ever had a Rem700SA in 6mm Rem will be more than happy to whine at you until Hell freezes over Over the fact that rounds seated to touch the lands for best accuracy will not fit in the magazine box

the 6mmRem 257Rob and 7x57 should all be chambered in a long action.

The "short action" really is 6mm too short for the ?x57mm cartridges, not suprising considering it was designed for the 7.62x51.

I wouldn't actually mind a Rem700 in 6,5x55 if it had a shorter throat than my swede, but if someone gave me one built on a short action I'd rather have a 260Rem.

GSSP-in order to easily get to 2900-2950 fps IME you really should go to the WSM case or something off a mag case.

The 6.5/06 and the 6.5/06 AI will get you there but not easily even with a 26" tube.

In my experience, shooters who seat long skinny bullets out to reach the lands single load, so OAL is not a big problem. For hunting, the SA box at 2 13/16" should be more than adequate for most good hunting bullets.

The Short Action was designed for the 300 Savage and 257 Roberts (57mm). The 308 cartridge didn't come along until 5 years later. And it was another year or two before Rem chambered it in their rifles.

My dad has a .224 TTH in a 700SA. He shoots 75gr in it and they are to long to feed thru the magazine. It's pretty much a one shot wonder. It does shoot exceptionally well so rarely do you need the fast follow up shot.

Well as a shooter of the 6mm Rem, the 6.5 x 57 and the 6.5 x 55, I'd never have anyone of them on a short action... Their is a major increase in performance when chambered in a long action or a Mauser length action...

Just my preference... anyone else can do what they want, but give me a long action with those cartridges any day, or else just build a 243 or 260, if you need the short action..

what about the 6.5 creedmooor? 2800 fps (28 inch barrel) and the pic on horady's website shows it in a AR mag (shorter than the 260). Dont feel like reloading? pickup a box at the nearest midwayusa.
