I'm experimenting with some JoAnn Fabric Linen now. In a range outing last week, at 25 and 50 yd targets, it loaded much easier and shot as tight a group as the pillow ticking I usually use. Tomorrow, I'm going to try it at 100 yds. The stuff I bought was stock no 400069026704, 100 pct linen. My calipers say it's .015" thick, but will compress down to about .012". I tried my usual olive oil based lube on it, and it didn't work worth a hoot. Spit lubed, it worked great. The moral to the story is you'll have to experiment and see what works for you and your gun,or even if it works. JoAnn's also sells 70pct linen, 30 pct rayon, which I had some scraps of and it worked really good, in another rifle, but for now I'd rather try to find a pure linen solution.
