Six inches low

[billtool]

Gunsite .308 shooting 3" high at 100 yard with shit ammo 147 grn Tula steel cased sporting a Trash Panda suppressor keeps about 1-1/2" group - a little less. Put 200gr quality subsonic rounds down range - six inches low. Kept great groups though. Very unexpected.

Good grouping is golden.

I put the 400 yard reticle at 100 yard zero and nailed it 3" low. Memory bank click....

The twist on that barrel must get those 200gr very stable. Pretty quiet ?

I just was really surprised that the lack of power would drop the bullet that much. First time out with the trash panda. 100 years +3 inches is where it was zero'd before the suppressor. Dead nuts on after..

Very quiet. Crazy quiet actually. You planning on the AXXE shoot? I plan on bringing this one and we can do more testing....

In my ballistics tables, just about everything drops at the same speed. After the slug leaves the barrel its dropping. So the faster it gets where, the less it drops. Its getting to the target just a little later than the usual 2600 fps. Do they show the fps on the box?

Yes I will be there. Looking forward to it.

Yes - its around 1060/fps. zero'd at 100 yards - the box shows a 33" drop at 200
I didnt want to zero this round at 100 though. I like 3" high at 100. The super short barrel likely played a large part in the dramatic drop.

The barrel length would have more to do with velocity. To a point, barrel length=velocity=less drop. Too long or too short means less velocity and more drop.
