Building new 7mm?

[brokenvet]

7mm RUM & STW are not what I would call for light weight rifle.  With these calibers, you would need a magnum action, more weight.

Since you already purchased the barrel and asking about which 7mm cal.  I would think that you bought a rough un turned, un chambered barrel.


I would look into:
7mm-08
7X57 (my favorite)
.280 Rem
.284 Win

With the choices above, you're still within the standard actions.

The 7mm calibers are normally found in the 9.5 twist & 10's

+1 for the .280.   Nice round.

I haven't picked a barrel yet I can get any size length or caliber.  But I'm thinking 7mm might be a little big for a light weight gun

[elkaholic123]

270 WSM would be my choice 

[brokenvet]

If you get into the mag calibers, then yes.  NOT if you get into the calibers I mentioned and for the action a Ruger M77 are based on the small ring Mausers, well at least the old M77 with tang safety, not so sure about the MKII.

You can also look at 6.5X55; 6.5 Creedmore.  You do choose the 6.5 caliber ensure that you get a 7 or 8 twist.

.280 or 7X57 with handloads.......

I like the .280 Ackley.
6.5 x 284 sounds like a great option as well.

Now throw in the 270wsm and they both go out the window

140 Accubond at 3200

Tikka T3 action with Shilen barrel dropped in a McMillan Edge stock, perfect lightweight custom package and not a fortune

If you have not given the 257wby a look...it deserves it. 3600 with a 100gr pill makes for next to no hold over to 400yds. I have plowed through and through on elk at that range resulting in DRT.

280ai is a solid choice, feeds well has good speed for its case and tons of bullets, although I would still go 284 just for action length and accuracy potential.

A 6.5wsm, 6.5/284, 260ai....etc would give you a lot of bullet slickness capability but require more holdover than the Roy. For a sub 500yd hunting rifle, it's tough to beat the 257roy.

hey thanks for all the input guys all great ideas!  im leaning towards the 6.5x280.  i already have a 270 wsm and love it but i would like to varry my gun collection a little    and a feather light rifle isd next on my list.  the 7mm stw will half to wait for now.

A 6.5-284 will crush the 270wsm down range. The 6.5 bullets are slick as snot on an iceberg.

There's a reason the 7MM Rem Mag is the most popular of the 7's.   Just sayin'.

It's the Honda civic of cartridges. Nothing special, but. Most things pretty fair.

For dall sheep.....284. Light short action, super proven in the lr world, plenty fast for 1,000 yard sheep kills if you do your part.

Perfect!
