Thread: 303 group-bad bedding?

hey people.
Finally got to try out the 303 project. a couple of things to clarify. Using the Greek military ammo from GC, scope a burris 2-10 signature but while I've had it for years, its never been on a gun to try out although it would be a surprise if it was its fault. I'd more suspect the mounts/rings.
Firstly the 4 shot group-this was at 50m-one shot close to centre, second out and up to the right. This was the second group I shot
Okay I think maybe me-third shot close to first then the forth way out again. I must say that no2 and 4 could be around the other way but it doesn't really matter.
This is actually the second group. The first was a bit the same but way worse. I just put that down to me and maybe the barrel needing to settle down after an aggressive cleaning. I didn't post that one.
There is a 3rd shot there but that was me letting my son have a shot from a 303 for the first time and that was pretty close maybe 25m I've seen from comments about tikkas that this is very indicative of recoil lug and bedding. I thought that was two separate groups not pinging back and forwards.
Secondly I was very intrigued by the way the ammo performed. I filled the box up with sand so we could dig the bullets out to show my son.
We put a couple of 243's into there but they just blew up and vanished.
Possibly the fully disintegrated 303 projectiles were from starting at 25 yards, with the others at 50. A couple whizzed across the top of the sand so we didn't get those. Just surprises they blew up so much. The shell for reference didn't go off even after 2 attempts and I swear I had a couple that kicked more than the others and the first group mentioned had one of those.
Thoughts and advice everyone? This rifle hasn't been bedded as I wanted to get an indication how bad the barrel was but I might have to, just to rule it out considering it does put 2 awfully close together-didn't seem like a coincidence
Thoughts everyone?
