Morning Shooters
I’m looking for some insight from the shooters here.
As some of you might know I have been working with (mainly fooling around with) light loads and subsonic loads for my .223.
I have tried a slew of powders with a verity of power amounts and have definitely gotten the noise levels and subsonic noise where I want it. (I have a self imposed noise limitation where I shoot)
Now the problem: I have an accuracy issue on the first shot or two. Seems to be across the board using about all powders and bullets (some a little better or worse than others but still there with all loads I have tried) .
I mainly shooting at 50 & 75 meters and out of a 10 shot group the first cold barrel shot will go way low right (maybe 2” low and 1”-2” right). Maybe the next shot will be in the group maybe not. Then I will get 5 or 6 in a row that group to about ½”-3/4".
I say cold barrel but it seems more like first shot because when it’s grouping I can shoot one then wait 10 minutes and shoot another and still put it in the group.
I was lubricating the bullets for a bit better group at the low velocities I am shooting at (subsonic) so thought maybe the first shot was lubricating the barrel then the follow up shots were better due to the barrel lubrication. So I have quit lubricating the bullets but the first shot still goes low right.
My next thought was maybe it was because the powder was going to one end of the case as I was carrying the rifle. SO, is took great care in only inserting the magazine after the rifle was on the bench and pointed at target. I even made sure I racked in the first shot same as all the follow up shots. Still not convinced it wasn’t powder movement I tried (multiple times) before each shot (including the first) of tipping the muzzle up then lightly bumping the rifle butt on the bench (no help with low right first shot)
I have tried a 10 case set of primer holes drilled out to 3mm (no help).
Tried magnum primers including pistol primers (again no help).
I’m kind of lost on what to try next (therefore the request here)
At the moment I am loading two rounds first (using old pulled bullets) as kind of throw away rounds, then shoot them into the backstop, then start my shooting for effect.
Anybody have any idea what is going on? (16" barrel with 1:9 twist)
