[QUOTE="SArnold30, post: 1934468, member: 113697"] For what it's worth as a late addition to this post, here's a long winded update on my experiences developing a deer load with the TTSX in 308 Win. I tested 150's with a ladder of Varget vs.130's in a ladder of Win 748 out of my 1:10 20" Remington 700 SPS Tactical. If supplies were easier to come by right now, I'd have tested both powders on both bullets, but this is what I've got to work with. I found that the entire ladder of 150's (.77 MOA) had a better average than the 130's (.89 MOA), but this also accounts for a 1.34" outlier on the 130's. What caught my eye was that the 150's best group only produced a .69", whereas the 130's had two under a 1/2", and a third very close at .58". Further, the 130's seemed to be much more accurate in regard to POI consistently matching POA. In the end, I opted for the 130's behind 53.4 gr of Win 748, because it grouped the best in my testing at .37" and is exceptionally accurate. I haven't chrono'd it, but I'm guessing (with some modesty) that it's probably got to be somewhere in the 3,100 fps range. Here's the best shooting I've done with it yet, a .32" I got out of it last weekend. Can't wait for the opportunity to turn it loose when the season opens in 5 weeks, hopefully this guy is still around to test it on.
