Thanks so much Mac. You can only imagine the silly great grin on my mush looking at it right now. I'm testing ammo with her again tomorrow that Elliott and and Lewis have kindly sent me. She's putting Bisley magnums smack on the dot at 35 metres. I'm absolutely chuffed to bits with that for hunting. A lighter, faster, accurate target round is what I'm searching for now. This rifle is going to primarily used as a precision target competition rifle Mac.

When I'm finished with the tuning and tweaking I have planned for her, she'll be one of the finest, smoothest most accurate 97s in the world... Nothing less!

Cheers Mac. Hope you are alright mate.

Simon,

Not sure if your a member over at the HW forums but if not mate do a search for using bis magnums in a hw rifle under the legal limit. There are a few posts on there from the regulars stating although accurate in the hw they can cause damage to the piston!!!! Something to do with the weight of them not being ideal for hw's unless the rifle is FAC rated.

It could very well be tosh mate and don't mean to scare you as you will know more about the internal workings of a spring gun than me but its stopped me from trying out the .22 variety in my 95.

Would be nice to clear the matter up so I can try some if its a myth.

ATB

I have had a conversation months ago with Tony Wall about pistons being damaged and he said if a pellet is not a good fit in your breech and is loose this will cause piston bounce which will ruin your internals.

He never mentioned anything about Bisley Magnums but it may be worth asking him.

Ive got to phone him later so ill see what he says.

Si.

Please let us know si. I've heard it burns the piston out or something similar. Something to do with the weight of the magnums not being good for a spring piston rifle.

Aw f*ck a Duck! You mean there could be internal damage using these Magnum pellets? The fit of the Bisleys in my 97's breech is rather tight. I'm not getting any sense of piston bounce when the piston drives compressing air against particularly loose or stiff-fitting ammo. You feel it as a sort of dull thudding recoil on firing, if the round is too heavy or stiff in the breech; even though the rifle may sound with a sharp report... :icon_eek:

The WEIHRAUCH MAGNUM tin has a pic of an HW77 spring rifle on the lid. You would think if these were PCP-only rounds, they would use a pic of an HW100? This must be checked out thoroughly here... :hmm:

Hang on though.

David James aka HuntersVermin on Youtube uses an HW97KT .177 with Bisley Magnums to great effect.

:hmm: Do you think he might know something??

Christ you can go mental over this! :hmm: :blink: :blink: :huh:

According to a response I put on Weihrauch Owner's Forum, The heavy-for-calibre pellets DO cause excessive piston bounce which shortens the life of the spring. If it transpires that the only truly accurate pellet for my HW97KT is a heavy Bisley Magnum type round, and it takes a toll on springs but, doesn't damage anything else, I'm prepared to go through springs for it then!

If a lighter pellet emerges as a superlatively accurate round, that's what Ill use instead. It can't be any other way really.

I knew I had seen it somewhere. Looks like I'll give them a miss in my springer.

Right lads Ive just this minute got off the phone with Tony as promised.

Here is the gen from the the man in the know.

You can use Bisley Magnums .22 or .177 in a springer HW95 and HW97 or any other model but it will bring the power down quite alot.

If you have a .177 running at 11.7 with Magnums it will be over with a lighter pellet 90% of the time and is the opersite to pcps and how heavier pellets work in them.

A magnum will not break or damage anything inside the rifle at all, all it will do will cause a harsher recoil for the shooter.

He says that they are very accurate in a 95 / 97 and if your happy with the recoil then they are very good to use.

Si.

Hmmm does anyone have any .22 cal Bisley magnums they can send my way to see what the power drops to and what sort of group I can get without me having to buy a whole tin? I'll more than happily send whoever has some the equivalent in H&N FTT or AA diablo field.

Thanks for letting us know Si
