hi all, just wondering, my scope is zeroed in at 17 yards at the mo due to the area i have to shoot in, i did have the chance to shoot out to 40 yards today and the pellets were landing between 4 / 5 inches lower, im using rws superdome in 22. does that amount of drop sound about right over that distance ?. i know its technically a complicated question, just wanted a rough idea, thanx =)

Download Hawke ChairGun pro, it's free and very easy to use.

 

I've just checked ChairGun and at 40 yards you should see a 4 inch drop if you rifle is putting out 11 ft/lbs.

falcon is that for use on pc or is it an app for the phone ??? cheers Evo

yeah it makes sense as the projectile is constantly losing energy, ive been looking into the idea of a lighter weight 22 pellet, im guessin that would give you a flatter trajectory ?, are there 22 pellets that might give you a more 177 like result over distance ?

I wouldn't bother, the diference is minimal

Get a range finder or high powered scope with sidewheel, and learn to use your mildots or set up a turret set up like mine above, takes time but works like a charm.

 

With the above set up, I have never missed due to range problems, just my poor shooting lol

 

I used to prefer using my target gun for this exact reason

I like mtc scopes for the price, only downside is they are heavy, for accurate range finding using a scope you need high mag, mine iirc was a falcon something or other, 10-40x56, did the job well.

 

For a hunting gun get something with a good reticule and use a laser rangefinder, imo of course.

 

And put in the hours learning the ret, if needs be stick a sticky label on the side of your gun with the most common distances if you can't remember them all., quick glance down and there it is

 

Eg.

 

25 yards 1/2 up. 30yards zero

35 yards 1/2 down. 40 yards 1 down.

As above. I just used Chairgun to workout what hold overs I need on my .22. I have it zeroed in to 30 metres. I wrote down what the hold over is at 35 / 40 / 45 & 50, then stuck that on a bit of paper I keep to hand when im out. I use a range finder if im not sure of the land to workout the distance and its an easy job then to workout what hold over I need.

 

Scope wise, im just using a basic hawke scope without any mill dots, but its easy enough to estimate an inch or 2 over a target when your looking at it through the scope.

BSA mercury putting out 10.8 ft/lbs with a 15.9 grain pellet, 2.25 inch Very high scope mounts ( just to make the loopy trajectory loopier - and because its an eye relief extender )The pellet "rises" two inches to my zero, then drops again two inches at 40 yards, but by 45 yards its dropped another two inches so you can see that the pellet drops quickly beyond 40 yards. This gun is only used for ratting really, so its fine that my range is realistically limited to around 30 yards.

that graphs really cool, when i first fired my tx over distance i could see the pellet drop right off, for a wee while i thought i'd got a duff one lol it turns out i'd over estimated there range is all, i did loads of shooting as a kid so like most things it seemed further / bigger range at that time

i'll get me a pro sport one day and i'll get that in 177, my old rifle a webley exel was a 177 and i used to do lots of hunting with that.

when i got my bsa lightning xl i got it in 22, my technical understanding of trajectories and caliber wasn't what it is now i just didnt like 177 as it simply looked to small and insubstantial, now with my tx i got it in 22 coz i see that size as having more wallop i guess

no i think .22 doesnt have as much wallop as you call it lol..177 is faster and alot more accurate than a .22 as my mrs says size isnt everything haha. i can accurately take out rabbits at a much longer range than i could with a .22 and i had a .22 for 7 years

got to ask but where do you get a .177 is more accurate than a .22 ??? certainly not my understanding, they will both do the job and because the .177 pellet is lighter yes it has a flatter trajectory but to say its more accurate is not truthful i,m sorry to say,

 

neither is more accurate than the other , and i personally think a .22 does have more thump than a .177, i have shot pigeons with a .177 and the pellet has gone right through them, certainly doesn,t happen with a .22 it just smacks them for six and they dont get up

.177 isn't more accurate, but it does have less drop so a greater range. My .177 is zeroed at 35 yards and I know my pellet will hit within 1/2" of the crosshairs from 10 to 40 yards. .177 don't retain energy as well as .22 but at air rifle ranges pellet placement is more important than power.

the swings and roundabouts of 177 and 22 is interesting and its great to learn new stuff to inform "personal" choices and preferences, air guns opperate effectively within a very limited range in reality unless you live in the usa etc, people may have killed small game at 50 plus yards but that as i understand it isnt the rule. if folk want to humanely kill things at greater distances get a bullet rifle or join the army lol
