I have been shooting long range for over a year and every gun that I shoot off a bipod jumps to the left on the shot. I have tried a lot. Different load pressure, different body angles, different bipod. No matter what on all shots the rifle settles to the left. On my 5r milspec it's about 1.5 mil. On my tikka hunter 6.5x55, about 2.5. What should I do or try to fix the problem? Or am I just asking for too much and this is acceptable?
Rifle hop to the left?

Have you tried differing pressure on your cheek weld? My .308 hopped to the left with a harris when I had the comb set too high and had too much pressure on it for perfect sight picture. Basically my head was pushing the stock down and to the right on the shot.
If you've been dealing with this for a year across all rifles, it's time for some professional help where you can be observed, corrected and instructed on correct fundamentals. I just don't think a pointer here or there on a forum is going to do it at this point as the bad habits in your form are probably pretty well ingrained. I believe lowlight has some videos on this & that could help some but at this point a long range class I think could really help you. Pay the bucks, enjoy the trip and experience and come back an improved shooter
Anytime I get left hop, its a signal to me to pay attention to if I am using muscle to tension my right shoulder (im right handed) instead of just letting my shoulders naturally sit there.
Left hop is a normal consequence of the torque generated by accelerating a bullet down a rifled bore.
It is a manifestation of Newton's Third Law of motion which dictates that an action (spinning the bullet up to around a couple of hundred thousand RPM counterclockwise) generates an equal and opposite reaction (the bore twists clockwise, driving the right bipod foot downward and the other upward, elevating and yawing the muzzle to the left). If the common rifling direction were more varied, we'd be seeing right hop, too.
My approach is to use a slack sling, anchored fore and aft to the rifle so it supports the non-shooting hand's elbow just clear of the ground/bench/whatever. Leaning the upper body's weight down via that elbow onto the sling preloads the bipod feet down hard enough to eliminate the hop.
The other methods work, too.
