ive been shopping around and thinking of converting my remington 700 SA .308 to .243 i was wondering if the bolt or bolt face is any different. i recently looked at my friends 22-250 remington 700 SA and the bolt face is different. so do i need a new bolt?
 
Re: ..308 - .243 bolt

wow thank you so much ive been researching like crazy and cant find a real answer i know the .243 is essentially a necked down .308 so i immagined it would of the above listed which one is best for 600 yard shooting and also has a decent amount of available factory ammo?

Just search for cartridge dimensions and keep in mind your bolt face fits .473" caseheads.



As HDC-deadly pointed out, 308 and 6.5 Creedmoor have the best match factory loads. If you go 243 be sure you get a fast enough twist to run good high BC bullets.

THe 6.5 CM will outlast the 243 by a bit....where did you see otherwise?

other way around. The 6.5 will last longer.

WTF?, standing by to copy......
 
Re: ..308 - .243 bolt

I don't know why you wouldn't just stick with 308 for 600 yards?? It has by far the most available components, including dies, factory loads, and even data.....if your looking for less recoil, I guess I get it, but it's hard to beat a 308 for 600 yards or less...and others would argue for further than that

Because it just doesn't have the flat, wind beating ballistics of either the 6mm (.243) or the 6.5 (Creedmoor, .260 etc.) when pushed from a near equal volume case.

That said though, as a tried and true standby you won't go far wrong if you do go to the .308.

Sandwarrior, first I will say that I DON'T know, but I doubt it's much at 600 or less, I think that a lot of folks shoot the heavier weights in 308 specifically because of their wind performance, perhaps a 6 or 6.5 has better indeed, so that's a good reason. I know that readily available stuff is sure easy for a 308!
 
Re: ..308 - .243 bolt

i cant agree more but i have the .308 ive been there done that i cant argue with its reliability but lets face it i have an itch for a new project so for windy florida coast shooting something a little flatter sounds better. i need a new barrel anyways.....
 
Re: ..308 - .243 bolt

My 140gr 6.5 only beats a 175SMK out of my 308 by .2 mil (about 4") at 600 yards in a 10mph FV wind, so I'm not sure what great perceived benefit you are expecting....

There's a definite wind advantage with my 6.5 with 140 Amax's and my 7-08 with 162 Amax's over my 308 running 175's, but inside 600 isn't where it counts. If a practical match I'm going to is 600 and in, I'll use my 308 (or maybe even my SPR with 77gr 223's).
 
Re: ..308 - .243 bolt

sobrbiker thank you so much for your experience im actually looking at getting into tactical matches, i already shoot uspsa so if a .308 is best ill just stick with that and swap out my stock and barrel

fish301,

Typically, I get about 8" less drift from a 6.5x55 shooting 140 Berger VLD's @2750 (24-26")than my .308 shooting 175 SMK's @ 2600 (31-33") And from .243's shooting either Sierra 107's or Berger 115's that difference is about 10-12". It's not a huge advantage. In fact this is one of those great times to use words to live by:

"Having a really high BC bullet can cut your mistakes by 1/3rd or 1/2. The problem is somebody to your left or right on that firing line, no matter what he's shooting, isn't making those mistakes."

That's why I said if you went with the .308 and didn't trust what you see you won't go far wrong. There are always great shooters out there, who've spent a lot of time behind a .308, who will help you when they can.
 
Re: ..308 - .243 bolt

if you don't handload don't bother with any cartridge other than 308 6.5cm, or 260 they are the only ones that have a reasonable selection of factory match ammo. if you reload the 243 is awesome it is really easy to shoot well. it shoots flat, bucks the wind and isn't very hold sensitive with virtually no recoil in a heavy rifle.
 
Re: ..308 - .243 bolt

Not saying don't get a 6.5 or 6, but you are talking about barrel life so cost sounds like a factor.
6.5's with conservative loads have better life than 6mms with the same pressures, 7mm-08 wil have a little better than 6.5. But it takes a LONG time to burn up a decent 308 tube (this in itself may be a reason to get a different caliber if you think you may want one later-a good 308 won't give you reason to replace it anytime soon).

Plus if there's F-Class around you, F-TR is limited to 308 and 223.


sandwarrior-are the wind drifts you quoted above for 600 or 1K?

600 In this lower elevation, and typically cooler weather.
