Sub Sonic Low

[Fritzcat]

How often are the first shot low with subs?

[Alleycat]

low velocity?

Most of my shooting is in the woods or field and not over a chrono, so I can not verify. I have read in the past of people leaving a oiled barrel for first shot, but I do not.

In this context what do you mean by "first shot" ?

First shot after cleaning?
First shot from a lubricated barrel?
First shot on a given day?
FIrst shot ever fired from the barrel?
First shot when the barrel is cold?
First shot from a full magazine?
First shot after releasing the bolt catch manually?
First shot after lowering the bolt gently on the first round?
Something else?

Any of those could give a low first shot and each could have different reasons.
As to how often, the answer must be "only once" if it's to be only the first shot in any context.

Sorry for lack of info. First shot from a cold bore. Most of the time it is where I cannot use a chrono and is at paper and steel. I often grab one of my rifles and do a walk or watch a spot in the woods for hogs ect. and some times shoot 2 or 3 times to check sights. Seems a lot of times 1st shot from cold bore is a inch or so low. I try so keep check of my first shot.

I eliminated this problem with the switch to whisper. In 308 Subs it was a recurring problem. I think the 300W subs have enough pressure to eliminate the problem. Try some VV110.
