Loading a CAL vs BT10 bipod

[Back Spin]

Surprisingly, I’m finding shooting with a BT10 Atlas produces more consistent groups compared to the CAL gen2 I just got. This is with shooting a few different AR uppers in 224V and .223 over a few range sessions.

For me, it seems the slack in the BT10 allows me to get a more consistent load, whereas the CAL is rigid and I’m having a hard time discerning if my uppers with the CAL like a light or heavier load.

For those who have experience with both, was there an adjustment to be made when going from a BT10 to a CAL? If so what was the trick?

Apples to oranges comparison, but on my 17# 6.5 creedmoor tikka I don’t load the bipod with my cal. If I do it’s the slightest pressure. Seems to usually produce good groups that way. I treat the bipod the same way on my hunting rifle as well. The slightest amount of load and that’s it.

I sold my CAL and went back to the BT10 or BT46 for the same reasons as the OP stated. About the only way I could produce consistency was to leave the CAL unlocked, allowing some play. Anytime you have a tight interface between your bipod and stock/chassis, and load it, your are liable to put stress into the system which can definitely impede your consistency.

I’ll have to try unlocking / loosening the CAL next range session.

Shooting from a bench, I can tell my heartbeat imparts slightly more movement with a CAL than BT10 V8. The groups show it too. One upper will shoot 1.5” inch with a CAL and 1.25” with a BT10, so not a great difference, but it’s there.

If you’re noticing heartbeat, that’s you, not the bipod.

Perhaps. The bench top is plywood and tends to magnify any movement. To eliminate the movement from the heartbeat do I just load the bipod lighter?

I just find it curious that the BT10 would be more forgiving in terms of movement than the CAL.

Also want to add that I’ve seen the disparity in accuracy when I’m in prone and I do not see any movement of the reticle. And I’m not trying to load the CAL hard. Just trying to control the forward movement and no more (As @Kasey wrote in another thread). I do pull back into my shoulder a bit firmer with the CAL, but that’s because I saw better results doing that during my first outing with the CAL

It’s likely I need to practice with the new piece of equipment more, but I wanted to know if others have gone through the same thing and what adjustments were made between the BT10 and CAL.

I could never shoot well off bench. Try shooting prone. You can load bi pod and really get solid.

Never bought into the retarded wave of no-pan bipods. The bipod won't traverse (pan) until you do.
