I played some with Rifle Premium Round pellets in 5.51mm, sorted. My rifle is tuned for H&N Baracuda 18 and I did not change regulator pressure for this session. I started at 25 meter and set the HS so it shoots the RPR pellets through one hole the size of a 30cal hole. Then I moved to 50 meter and the group opened more than what I am used to with H&N. At first I decreased the speed with the HS but it opened more. Then I increased the speed and it formed a tighter group at 50 meter. Back to 25 meter and the group was bigger than before and decreases the speed again to shoot smaller group. At 75 meter it shoots better with the same HS setting as with the 25 meter, it is just at 50 meter the HS setting is different. I did not see any spiraling but as I understand if there was spiraling it will not reduce after 50 meter to be less at 75 meter. There was no wind at the time of shooting, all 5 shot groups. I hope the description makes sense.
Did anybody experience something similar?
Is this normal with some pellets?
