[QUOTE="Muddyboots, post: 2184193, member: 63925"] I agree with reelhardmt, here is some data from my Sendero with 181HH and 196HH last fall: Sendero G1 Version 26" 1:10 twist Both bullets seated to 3.62" max COAL standard Remington hinged magazine The 181HH and the 196HH jump was pretty close to each other at about 0.095. This is on barrel with about 1,000 rounds. RP brass - 0.002 shoulder bump ( I need to redo since I have switched over to Peterson brass.) 70 degrees (September 2020 data) Optical Light screen with sun shades measured 25' from muzzle Loads in bold are the ones I ended up with and both shoot 1/2 MOA out to 200. I have not had any time to stretch them out but do not see any concerns they won't shoot well at distance. They did hold 1/2 MOA at 300 as well.
