Nice groups Mercs!!! Well done!

If I can get my SIG .177 like your's at 50yds (Max spread 31.4mm) I'll be stoked! Smile

And the fact you used bipods on a Springer amazes me! I've always found the artillery hold (and your hand between the rifle and any rest) best - so, your use of bipods is most interesting.

Have you tried grouping without the bipods on your .177?  I'd be interested to see the comparison because your .22 groups (at 50m) without bipods is staggeringly good!

Max spread 14.4mm at 50 metres with your .22 is incredible!!!! Mega-Well done mercs!!!

I need to take lessons from you!!! Thumbs Up

Im not going to post a photo of my .25 hatsan groups from Tuesday....! 

Used to get 1 - 1.5 inch groups at 40m before the rebuild and now its doing 8" groups with a new scope!! 
I put a old scope on and made a little difference, so wondering if its two dead scopes...! ran out of JSB exacts for it so tested every other variety with not much better results so its left me a bit bazzeled and pissed off.

will try another scope before i take the thing apart

Got open sights? Quickest way to check a scope.

Hey mercs just went back to look at your volicities, you are shooting right in the transonic range with your 177.
That volicity is the most unstable for pellets. Two of the pellets you mention are smack in worse zone.
It could explain the wider spread for the 177.

Wind disappeared for a few hours so back out with .177 on 50 metre range for some fun.
Scope Tasco 3-9x40AO set at x9
Bench rest with rifle on bag instead of bipod. 

H&N pellets 
I note the Baracuda variation is vertical but Hunter Extreme variation was horizontal.
First shots of the group are tight then deviate so most likely something I am doing.
Next time out the first 2 rabbits within 50 metres are in trouble.

H&N Baracuda 0.69g
OD 37.3mm
Well worth working with.


H&N Hunter Extreme 0.62g
OD 37.8mm
Low penetration and or pellets fell out.

Nice one Mercs!

Those groups are superb at 50m! Big smile

I'm still waiting for less wind to continue my testing but I'm hoping my groups turn out like this!

So just ran sig over chrono with pellets for hunting hi 905fps lo 897fps
Ave 897 fps
If like to drop that around 850fps, what would be best way to do that with out increasing pellet size.

Those are great groups for 50m.

Not sure on dropping the fps without using slightly heavier pellets. Others may have some ideas.
