I shoot the 7.82 Lazzeroni Patriot which is very similar to the 300 WSM
, I started with the 150 TSX & RL-19 (ES & SD both single digits), which my rifle absolutely LOVED, I was able to make first shot hits on targets out to 967yds (farthest tried), of course retained velocity & energy were terrible due to the low B.C. So I moved on to RL-19 & the 180 MRX @ 3150, good accuracy but as I started to weight sort, I notice WAY too much of a weight spread (up to 2grains in one box), so now I am on to the 168 TTSX (much better weight spread) with RL-17. So far it's showing some promise but still in the eval stages.
I figure the 168 TTSX @ ~3300 will be plenty for what I intend to do with it, I was disappointed with the MRX as my hunting partner has GREAT success at 500 and in with his 7RM, but alas, I wanted/expected better, I guess that's why Barnes has announced the discontinuation of the MRX.
