   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! 

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!!!

	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! 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.

	That's sweet. Gonna resight sig for 28m (if the wind ever stops) Turns out (according to gun chair) With my weight pellet .67gm and volicity 897fps, it will give me a lot better hold over readings on mildots. .5=37m,1=44m,1.5=50m,2=55m, 2.5=60m,3=65m, 3.5=69m,4=73m,4.5=77m,5=81m Which is awsome for the 50m to 65m range, which is where I need to be for hunting hare here. With 20m and 25m just above the windage line. Lot easier to rember than last sighted zero.

	Hi Kruza, I too use holdover/holdunder with mildots at a chosen scope magnification (x16). I build my Ballistic Charts from 10yds-100yds, at 5yds intervals - eg: 10yds, 15yds, 20yds, etc... I do all of this manually by moving the targets to the desired range, shooting my groups and then checking through my scope to determine how many mildots above/below I need to holdover/holdunder from zero, at each chosen range. I'm mentioning this because I believe everyone's scope differs and if you use only Chairgun (or similar) to setup your Ballistics Chart, it won't take into account the specific optics of your specific scope at each range. Does that make sense? Not only that but it's also fun discovering your particular gun by walking up and down the range, moving targets 5yds at a time and using your own scope to determine the amount of mildots you'll need to holdover/holdover at each and every range. It's time consuming but it does give results relevant to your particular gear, rather than relying on generic electronic calculators like Chairgun, etc... And it's interesting what you find if you do it manually - for example, on my particular scope on my S410 PCP, there's a point (135yds) where the holdover is the same as at 130yds! The holdover (9 mildots) should of course have increased from 130yds to 135yds - but it doesn't! It's just the optics of my particular scope that, after focusing at 135yds, I have to use the same number of mildots holdover as at 130yds!! Odd but true! And I would not have discovered this if I'd just used Chairgun alone.... Hope this all makes sense?

	Totally. I think further back up I have the two differnt flight paths in mildots between AA and exact done as you do. However gunchair with info in it will put me right in the ball park, and as with all things fine tuning will be done manually. Its the same with mildot ranging, have distances by mildots from calculations but at end of day, stapling a hares head to a post (eeeeewww) and setting it at distances allowed me to measure and record how I see it through the scope. I agree with totally, but gunchair has given me the range to work in and I can retune the data from there. I also found that acurate scope height for gun chair is a vital bit of info that improved its prediction when I used the vernier to measure it, once I'm Sighted in I'll throw the chrono up by the targets and work out the true ballistic coefficient for the pellets, which will further fine tune the app.

	Page two of this thread. AA df heavy, exact heavy both weighed and weasured to same specs.

	If any of you guys/gals are keen to take your favorite pellet/s for the sig and do a bit of real life drop measuring, post it, it would be rather interesting to see the flight chararistics of them, then compare them to others results and see if there's definite flight paths veriations that ring true for a certain pellet. Thinking AA, exact, barracuda be good starting point as seems to be the most recommended by users here. Prob need the zero for your distance you are set at too. If you could provide volicity that be a bonus. Once this weather stops! Edited by kruzaroad - 06 Jan 2023 at 3:26am
