I am considering building up either a carbine 16" or rifle 18".  It will run with a scope, either a Leupold M4 variant or NF 3.5x15x50 or 2.5x10x24.   Will run with and without can.  

Is there much difference in accuracy between the 1x7" 16" SS barrel and the  1x8" 18" SS barrel?  I plan on shooting 75-77 grain ammo.

Thanks,
Darin

Not much difference from what has been reported here.  I'd recommend the 16 with rifle length MRP

My 16" SS Rifle Length MRP is an absolute tack driver, 1/2 MOA with most any "match" factory loads (55-77 grain).  
My 18" 1/8 SS barrel only gets that level of accuracy with the lighter bullets, 75 & 77 grain were only just under MOA.
I think most others have had very good accuracy with the 16" SS barrels.

interesting, not to turn this into an ammo thread, what distance were the comparisons shot at?

This was at 100 yards, excellent conditions (different days but conditions good), concrete bench with rear bag and bipod front.  Hornady, Federal, Black Hills, Winchester ammo used.  The 18" really likes the Winchester Ballistic Silvertips, 1/2 MOA multiple times, the 16" likes everything.

Send me some of your Mk 262 and I'll try that too (LOL)!  Just kidding, but I do get very very good results in a couple of barrels with the Blue Box 75gr BH load (18" Krieger SPR 1/7 and 16" 5R MRP 1/7 barrels).

roger...

i just bit the bullet and ordered  a case for my precision rifle case in april.  With so much conflicting data, i wasn't sure with what grain to go with with my 18inch, 1/8twist SS pacnor barrel. Only shooting out to 300yards...

I figured, might as well plan on it being windy, and go with the 77SMKs...

I haven't had much chance to figure out what the barrel likes the best, but honestly, BHs seems to work all around..

Edwin907,

Wow, your gun matches one of the options I am considering.  Very nice setup!

Everyone,

Thanks for your input!

Thanks,

If you are going to be running it with a can I would go with a 16".  I alway run my 16" MRP (1/7 SS SPR contour) with a AAC M4-2000, great combination.  So far I have had the best groups with Hornady 75.

Jack, what kind of effect do you see on accuracy with the AAC & 16" SS MRP barrel?

many thanks,   Edwin

Thats good to know as I have a QCB 14.5 permant Vortex and a rifle length 16" and I was thinking of getting a 18" for it but I guess I wont.  Where did you get your SS barrel as mine are standard CL.
Thanks
