I have a question. I recently purchased a Sendero II in 300 RUM. I had a box of 168 grn TSX and thought I would try to find a load that would shoot with what I had in the reloading room.
I started at 100 grains and had no pressure signs at all. I did the shoot clean shoot clean break in then tried groups of three clean three clean. The groups were in the 1 1/2 range.
I loaded three each with 101grns, 102,103,104,105 and 106. they shot about 3inches at 200 yrds with hardly any pressure signs till I got to the 105 loads. The group shrunk about in half and the primers started to flatten. The 106 loads went down to about 1 inch with the primers flattened pretty good and the bolt lift was slightly changeing.
My chronograph was not working and am wondering if anyone else has chronographed this load so I have an idea what it does for velocity. Anybody? Thanks, Jeff
