Converting your SAAMI Chamber to a SPCII. SS or Chrome.

[0311]

I have the same barrel and the same question. Would putting a SPC II chamber on a 1-9.5 barrel be enough of an overall improvement to be worth the work and expense? Or should I just use that money as a down-payment on a SPC II 1-11 barrel.

Thanks,

That's a decent twist if you plan on loading subsonic rounds for suppression, might be worth it if you ever plan on that. If not, I will keep my opinion out of this.

My 6.8 has one of the older 1:10 twist barrels from DPMS.

It has been reamed to SPCII and seems to shoot alright, although 120 gr Hornady is the heaviest I have currently tried to use in it so I won't comment on anything more because I don't want to speculate. So far so good though.

Thanks for the info. I use mine (Model 1 upper on a DPMS lower) mainly for plinking and just-for-fun target shooting. (And home/self defense should the need arise.) It doesn't need to be a "Super Match" rifle. It's been a while since I decided I wanted the SPC II chamber so I need to do some research to bring myself up to speed on the chamber issue before I decide. So I'm off to the search page.

Thanks again,

I ended up sending my barrel to Ballistic Advantage in FL, and they did a phenomenal job on the chamber reaming. I had the chamber reamed from Spec I to Spec II. At first, I shot some commercial Hornady ammo through it, and the accuracy was terrible. What I didnt know is that the barrel twist was causing the bullet to shed its jacket, thus throwing off the symmetrical spiral. Once I reloaded some Barnes 95 TTSX with some AA2200, it was a completely different story. The all copper bullet and powder was a very accurate combination which gave me .5 in groups at 100m. Bottom line, I would use Ballistic Advantage for any and all barrel or chamber projects. Class A company!

Is a reamer still in circulation? I'd love to use it on my saami. How do I get in on that?

If someone with a reamer does not chime in, I believe you can rent reamers for almost any caliber from http://4-dproducts.com/index.php

wxl, I'm awaiting a call from a guy with the reamer. Thanks for the help.

This may have been covered prior in one of the 33 pages of this thread, but time is money for me, so I'll take my chances asking:

Will these reamers work on the ruger mini-14 ranch rifles in 6.8?

When I had mine done this morning, it appeared the handle of the reamer was specific to the ar upper reciever. I know the man who did it said he had a handle that worked on another rifle, I just can't remember which. I sent him an email asking about the mini 14. I let you know asap.

ROPO68, this is what he said,Only if the barrel is off of the receiver.
Otherwise it requires a pull type reamer
