A little bit late due to various issues, however I have some results. Targets were 100 yards, 1st target was dialling my scope in so 2 shots to get on target and the rest, well, you will see.
1st target, factory federal powershok 140g, 1 shot high, 1 shot low, then 3 shots dead centre coming under quater of an inch. Not too shabby.
Left the factory rounds and tried my starting loads, using the 130g sierra gamechanger, viht n160 powder and hornady cases.
Virtually all groups came under half inch at 100, with 2 of the 4 being .4 inches. The best group of the day was a ragged hole that measured 0.152? I think it was (zeroed caliper at .264, apparently that's how its done 'properly')
To summarise, nothing wrong with a howa. This is my 3rd one and I see no reason to change to another brand. They are cheap, cheerful, doesn't matter when you drop it or cover it in mud and blood and with a little bit of time will shoot groups as below. A little bit more time and it would be a consistent quater moa rifle all day long. For £540 quid...
£540! Can't even get a rebarrel for that!
Edit to say, yes the first shot on the first picture i DID pull, said I pulled it before I shot the others lol
