My Beanland 260 8.5tw Krieger on a trued bp 700 action, is my newest Match gun, and I have ran every powder made through it. Varget does fine with the (123-130gr) pills, but H4831sc is what I shoot my 140 Berger Hybrids, 139 Scenars, and 136 scenars with much better accuracy than H4350. I can push the 140 Hybrid to 2850 with 47.9gr, on my 24" tube, but due to the Scenar's ogive I can't get enough powder without "over compressing" the load. And 45.1gr shot a 2.97" group at 600yd last weekend, so doping my scope a tad more is no problem for me, as I'll trade accuracy for velocity anytime.
Also don't forget to do yourself a favor, and run 4064 powder as well. I laughed at this over on the hide, but come to find out, it's a darn accurate powder in the 260. It's too bad, because I bought tons of H4350 for my build, but I also found a cpl 8lb tubs of H4831sc at my local FFL, and H4350 shoots great in my 243's, and 6.5 x47's. I like RE17 for velocity on the mid weight pills better than Varget, but both shoot great.
