OP - Here's my journey:
- bought T1X 20" in 2020 : still have it in the safe
- bought Bergara BMR (steel) in May 2022: (gone in Sept 2022)
- bought T1X 16" in Dec 2022: it is a keeper
I did not have luck with
MY BMR, like you, I shoot CCI SV, and some other mid grade stuff like SK Std, Norma Tac22, Wolf match, etc.. and some cheaper Aguila SV, Geco Rifle, Federal automatch, etc..
MY Bergara did not like any of the food I fed to it. It was returned back to the mother-ship and I got my money back. Some members are much luckier than me, they are happy with their BMRs, but I gathered that their BMR shoots good with higher grade ammo - which I cannot afford.
Both of my T1x do not require trigger spring mod. they are both set to 8 oz pull just by adjusting the set screw. zero slack, zero over-travel. No need for any trigger upgrade or trigger job. (truth be told,
MY Bergara had a very good trigger too). All I added to T1X are a DIP 25 MOA rail, and a Tikka vertical handgrip, total cost is about $50-$60. (And a $40 cheek riser -- but it is a standard setup to all my rifles, T1x or Bergara regardless...)
Above is just 1 person's experience. Happy shopping.
(Something else you may like to consider: Tikka guarantees 1 MOA. Bergara guarantees 1" at 50 yds (aka 2 MOA). Both are based on high grade ammo, of course)
