They shoot to the same spot and group size was very similar even though the TTSX's have to be seated a little deeper due to the more tapered ogive. More groups right around 1inch @ 200 yds. I think this is the "Sweet Spot" in this rifle. Thanks for everyones input.
Yeah, I'll give you that, in that every rifle is different, particularly chambers. Another variable with my load, is that I'm using A Square brass. I am not for sure on this, but I believe that Norma made that brass for them. It is quite heavier then any of the domestic brass, and my FPS went up when I switched to it.
And yeah, 84-RL22 is SMOKIN hot, in anybodies gun!!!!
RL22' used to be my " go to " powder for the STW. I bought some RL25' for my 300 RUM. So one day, trie it in the STW, and the rest is history! It dosen't seem to be as temp sensitive, which we all know that 22 is. Also, have noticed that ES, SD, are lower. The ES, SD, are secondary concerns for me. If I've got a .375 group all day, I'm not changing anything to drop the numbers. The deer don't care anyway, they can't read!
Take care my friend!
