Spent some of my precious .338 300 grain Matchkings today because I moved the scope a little and also wanted to re-zero my TRG-S for bipod use. For some reason I also seriously over-tightened all the bolts that keep the thing together. About a quarter turn each,they already were quite tight. This light TRG-S varies a lot,depending on the support I use plus it has (had?) a bedding problem (probably?) so the POI keeps drifting. Or it used to. 30 F today. Anyway,after some fouling offhand shots (no more moly in the barrel) I looked for an approximate zero point ,using my car as a support and a Harris bipod,standing. Found the spot, fired three rounds from 130 meters. I was able to repeat this for several more similar targets but my bullet supply is getting low... no, it WAS getting low because I just received a package,15 minutes ago. Thanks again,Dave! Can it be just the loose bolts? Hell,these are so tight now, I´m almost scared -but this is the real way a healthy TRG-S shoots. Ideas? 170 rounds through this,only moly at first. Just when I decided to check the bedding,everything is fine. Less than 1/2" inch three shot groups from 130 meters,Harris bipod, can´t complain. Poor deer.
