Calculate your own BC with Si Pittaway

[@GaisaSanktejo]

Thank you, your post prompted me to find the chairgun app and with that, I managed to work out the BC of my ammunition 😁

[@ClotEastwood]

Hi Si. . . another good bit of info . . . thank you. . . hears a quick bit for you. . . to measure the centres of any hole's (your drawing pins centres as example) measure from the side of the hole to the same side of the other hole . . this give the centre measurement. . . so . . the top of the top drawing pin downward to the top of the bottom drawing pin. . . gives the centre . . . . drawing pins or actual holes. . . works a treat . . . . thanks again

[@horridhenry1805]

You must be a joiner pal

[@ClotEastwood]

Nice vid. When measuring centre to centre in engineering. . . measure between either both the tops or both the bottoms of the drawing pin (if they are both the same diameter) this will give the centre without need of a little wobbly guesswork . . . it will be exact. Whoops just read down a bit and I said this a while back. Keep the Vids coming VHTV

i used a similar method on hawk software, what i did was changed the B.C. in box provided until the B.C matched my impact point on the graph, mine was done from 15 yards to 25 yards, same aim point just zero set at 15 yards, as i changed the B.C. the arc started to move and then i simply stopped arc when the graph showed pellet height at 25 yards showing my B.C. its a neat feature i have known for a long time, it was a way to get a B.C. with out shooting over my chrony for muzzle velocity and then over it again at 25 yards. the software works good for sight in also, as you keep typing in sight in distance yard by yard until you get the arc close to line of sight or what i like is a half inch below line of sight, and similar to the field target setting you showed in hold over hold under video

Si 50yds & 60yds w/Your .25 w/19.9 FTT @ 12flb. Thank's , Your Vid's are the Best from U.K.

[@btownbuye]

Exactly what I was going to point out. The only way to make this a reasonably decent way to measure BC is to use a chronograph in tandem with your bullet drop. And the software will also take that data. however Si did not use his info just stayed with the stock info in the software

[@grahamellis3178]

Good information, and loved the vernier the way the lower scale measured a whole mil short

[@peterobinson29]

Great video thanks Si.

[@lensman5762]

Thank you. Very well explained and demonstrated. ATB, A.G

[@feiz01]

get simon, lol,"im not the best shot" si man, your a fantastic real world shot, end of lol some of the shots you make with the airarms pro springer are amazing mate!

[@FAISAL42448]

Really Sir your good teacher

[@PeakyBlinder]

What is the better option, velocity or measure.

[@davequick2821]

cute desktop screen.....nice vid.

[@lakaboo86]

Nice video mate. I mite be geting a BSA R10. Would you say it is a good choice.

[@harrygmarshall5157]

Thanks for the information Si, I like the reticle in this segment , what is it called and what scope is it in ?/

[@carsmax]

Si . Why does it not work for other scopes ? Example my Athlon 6x24 x50

[@mejia1133]

The target it must be at 40m or at what distance should I do it ? I normally shoot between 30 and 100 yards, Thankfully

[@Sertao2013]

With the pellet . 15.9 22 cal pellet what is your guns fps .

[@nontimebomala2267]

Si, that micrometer is calibrated upon the CENTER mark not the first mark. It was not 9.1 cm. It was 9.4+/- a half mm. I have one exactly like it. Just information you might find useful.

[@colliedogjoy]

After extensive research, I think you're wrong, respectfully. I think his Vernier Calipers read 9.10cm. The lower scale reads the 2nd decimal place, which is aligned at 1, therefore it reads .10....

[@Gary1973-1]

Hello Si, just a quick question are the RWS Superfields you used the jsb variant or the newer RWS ones.

[@MrFREDANG]

hi, do u hold your breath when shooting?

[@85k11]

what o mate got something to ask . with a 22 air rifle zerod at 25 yards what will be the first strike point will it be 10 yards .

[@jeremiah6864]

My guess is that a zero at 25 yards IS your first "strike point" and that the second is somewhere between 40-50 yards based on a scope height between 1.5-3" off the barrel c-to-c.

[@ThePhan7em]

is that the FAC R10 mate?

[@Zinaroon]

Thanks Feiz buddy I guess that i had a good day that day. Si

[@SalehMagrabi]

Thanks 👍👍

[@roydredge1273]

Si what is the name of that software again Thanks

[@ghostsniper77777]

Link the app please

[@Zinaroon]

Hi laka, I love my r10 so i would have to say "yes" to your question pal. Im not the best shot and for me to get almost 5 pellets in the same hole at 40 metres with a .22 calibre r10 the rifle has to be good. Si

[@luisvazquez3703]

good information

[@ghostsniper77777]

The sofware link please

[@redneckbennett1973]

Thanks

[@fym125]

nice vid lookss fun wish i had some permission where i could go just to do some target shooting,, and that vernier looks old :)

[@Zinaroon]

No problems Multi buddy. Si

[@Zinaroon]

No im not on the owners group. I was but i didnt like how the mods treated me and my friends so i left and so did my friends. Yes have mods but they dont need to try and show everyone that they have power. Si

[@Zinaroon]

Hi Mr Fred, Yes i do to stop my diaphram from moving. Si

[@ferret756]

Hawke ChairGun Pro roy dredge

[@roydredge1273]

ok got it

[@Zinaroon]

Ian are you real or just a total idiot? The permission was totally safe and no one would of been injured. Go and bug someone else in the arm chair hunters section. Si

[@ddimkinn]

Скорость маленькая очень, поэтому всё хреново, на 100 метров не стрельнёшь....
