I just used my Bergara with Prime 130 gr for the first time yesterday. I liked the results far better than Berger 140 gr.
I use the 140's with my Tikka T3 A1 and get phenomenal results. The Tikka, out of the box and once setup, was hole-on-hole at 100 and I took it out to 600, for the first time in my life, with surprising results.
I am having issues with my groups with the Bergara, but I can't blame the action/rifle yet. I need to futz some more with myself to make any judgement. But the difference in ammo was noticeable enough for me to add to this thread.
When I used the 140's my groups of 5 were scattered circular around POA. The 140's, over several strings, were all straight vertical tracks. (100yds., no wind, spotty rain.
Funny side note - as it was raining, it eventually got to the point where I had to pack up quickly and haul everything to the car. I got home about xis hours later and found the Bergara barrel had, surprisingly, started to rust. To the point that it took oil and 0000 steel wool to clean up. All other rifles, and gear, simply needed a paper towel wipe down.
So if considering the Bergara, you may want to find out more about the finish as my situation may just have been a one-off.
