JSB exact pellets. Normal 8.44 gr or heavies 10.34gr for sub 12 springers????

With less than 1/2 ftlb between the highest and lowest I'd choose the best performing pellet & ignore the chronograph. If the heavier pellets stand better in wind as Phil says "you can learn trajectory exactly".

Yes.

Yep, definitely a good idea to let it run in a little more, Rhys.

If the power didn't rise and it were to still niggle you, a tad more preload to compensate a little more for the lower swept volume will help.

To be honest tone, I can't wait till I forgotten all about the power its pushing.. a couple of weeks ago I put my mate with his Webley raider 10 PCP to shame with it . As soon as I'd zeroed it with the a different pellet I was hitting this small target at about 45-50yrds nearly every time. It was great

Coincidentally someone else has started a thread about the 77 today

I think if the rifles working for you its not too much of a problem. I'm going to have a look at the 77 when I get chance as its never been apart and is pretty twangy. I'm just reluctant with this one after I marked my Nickel HW97 taking it apart. The new ones seem to be a right pig to open up.

Setting aside the issues with the rifle's preffered pellets, (which will almost certainly be the 8.44g btw) the whole point of .177 is it's flat trajectory. Whyu comprimise it with a heavy pellet?

Why use 8.44 when you can go 7.9. They target shoot better for me if paper...they drop better longer if it blinks and maximise pellet traj too.

No brainer for me. I dont really see any advantage in heavies unless its got FAC type air up its arse.
