Hw97 guru’s

Ok bit of back story I have a 97 and I sold it to a member here and was contacted a couple of days after saying it wouldn’t group so I took it back

It’s been a while but I’m getting round to figuring it out now I’ve done a 10 shot chrono string and the difference between the highest and lowest was 16fps low being 548 high being 564

There is a bracket which holds the front of the stock to the action and this is loose

Should it be loose of should it be fixed

The action is not moving in the stock so I’m guessing it’s fine

I’m going to shoot it tomorrow to see how it groups myself I have a picture of the bracket which I will try and add to this post in a second

Perfectly normal for the bracket to move.

Cheers mate I thought it may but be on to the shooting tomorrow then see how it groups

Well had a few shots with it and grouping is terrible first group was 10 shots and they spread over about 2 1/2 inch chrono said 16fps difference highest out the 10 shots was 564 FPS lowest was 548 put another 50 shots through and did another 10 shots group was about 2 inch and chrono says 13 FPS difference high being 570 FPS low being 557

Currently have it stripped for investigation

Is it a 97k? Has something worked loose in the silencer causing clipping? Very intriguing.

I take it your using 16 grain?

I have just built a 97 out of spare parts I had in the bits n bobs boxes, I saw very similar groups to you with Falcon accuracy, now these usually work extremely well In a HW barrel, I then tried Premiers and FTT and the FTT were doing 20mm five shot groups at 50yds!

you can physically feel the FTT heads bite into the rifling as you load whereas the Falcons fell in, so I can only surmise the barrel is a first off production run when the mandrel was new.

The bracket is always slightly loose by the way, If you have any concerns about it run a liner of tank tape on either side of the stock inletting and trim it to the slots with a scalpel, this helps the stock screws pull the rifle down into the inletting and eliminate vibration.

I think it should be loose , it is on my HW77 anyway and that shoots spot on !
