OK, I have built a very nice lower and decided I wanted to venture into the caliber 6.8SPC. I did a little home work, or so I thought. I found out there are two chambers; the SAAMI (SPC I) and the DMR (SPC II) and that the better chamber is the SPC II so that is what I got. I did not want the current Fan Boy rage 16 inch barrel so I started looking around for at least an 18 inch unit. I settled on a Model 1 upper with an E.R. Shaw 18 inch medium contour stainless barrel with a SPC II Chamber. For those of you who do not know E.R. Shaw is made by Savage so it should be pretty good.
Now here is where I started going off the trail a bit; the barrel has a 1 to 9.5 twist rate. I applied what I know about twist rate from other calibers that the tighter the twist the heavier the bullet you can load for and shoot. My thinking was I could go as high as 130 grains.
Now today I get my American Rifleman magazine and there is a very well written article about the 6.8 SPC. Well in the article it reads that Randy Luth the former owner of DPMS did some research and determined the twist rate of 1 to 11 did the best.
Anybody out there have any experience with the 9.5 twist barrel in 6.8 SPC. At this point I will be using the barrel I have so please don't send me negative information just looking for somebody who can help me salvage what I have. Recommending bullets or loads you have had good results with is what I am looking for. Wish me luck.
