68yds with the longbow

[remorem2jh@supanet.com]

Can anyone explain this i had another go at 68yds this evening .
1st group shot on 9x mag 71mm (4shots)
2nd group the same settings 54mm (7shots)


3rd group on 4x 24mm (4 shots)
4th group on 4x 37mm (5 shots )

Now how comes on higher mag the groups are twice the size.
There was a head wind but it was fairly constant.
pellets used Webley Mosquito.

Hi.
I find this with all my shooting, the lower the mag, the tighter the groups
I now hunt on 5X, as its my most accurate. FT I still do at 40X.
I put it down to the lower wobble through the scope at the lower mag, enabling a tighter group.

[remorem2jh@supanet.com]

I usually leave my scope on 6x untill i am in the trees the back to 3x when hunting.Thinking about it those were the first shots i took so probably was just honing my self to the gun.

hello mate,
it could be as the target is easier to see at higher mag,you don't concentrate as much (as your brain thinks its easier) ?

well thats what i find

JASON..

Maybe JJ maybe , I think it's just when i am zoomed in the target seems to wobble a lot due to my poor 'spot weld' while shooting with my van based hold.
Nice to hear from you in a different venue bud.

Have found that the higher the mag the larger the wobbly factor, and correction when holding over or aiming off,
also if the scope don't quite suit??

Went from AGS 3x9x40 to Richter Optic 3x9x50, realising I aint no spring chicken and need all the help I can get within my small budget,
shifted to BSA Essencial 44x4x12 Bingo! a scope that suits both my eyes and wallet, shoot mine at 9x on both my HW 77K and Lightning XL both in .22in,

As for pellets, Accupel for the 77K and JSB's for the Lightning, Webley Mosquito's do not suit either.

[remorem2jh@supanet.com]

I had AGS 3x9x40 but did not like the wide dot spacing.
I have a Richter Optic 3x9x50 on the lightning.
got Bushnell Trophy's on the s410 and Longbow.
I had a BSA Essential 4x16 x 44 but never much liked all that manification .
I like the Trophy's best
How do you find your Lightning ? i find mine very jumpy with its Venom kit installed the Longbow is much easier to fire.

Isn't parallax more critical at higher mags? Perhaps it's not spot on and causing the problem, mind you I wish I could shoot groups like that.

[gunpowerchris]

i reckon on the higher mags you see the cross hairs moving more so you over compensate or try harder and thats where it all goes wrong

[somnophore]

68 yards, you are basically lobbing a pellet at that distance, i havent got a scope atm, im stuggling to get 30mm groups at 20 yards open sights, but just got my webley stingray, so still improving, not sure how a scope would work in that, at it has a large precision front sight.

I use a 10x44 on my rifle & I have hit 1in targets at 50yds consistently using 16gr Logun Penetrators so I reckon it's just that you get on best with your mag at that setting. Everyone has different preferences so that might be yours. Failing that, it could just be parallax error as previously stated. Also, you might have a few dodgy pellets in that particular tin. Having said that, shooting at them sort of ranges with a 12ftlbs rifle there is a good chance there is going to be incosistencies with the POI as the pellet will have lost alot of its strike energy. I'm probably wrong but it might be worth looking into all the same. I hope that this is of some help.

How about this? It's only a theory but it makes some sense to me.
High mag = lots of more wobble. Your brain will tell you to release the shot the instant your eyes tell it you are right on target. Result more of a snatch on the trigger as you try to fire at that precise moment (even though you know you shouldn't) Snatched trigger = larger groups.
Lower mag = a lot less wobble. Less presure on your brian to say NOW the second your eyes tell it you are on target. So a much smoother release and a tighter group.
I also find lower mags give better groups. Although at anything beyound 50 yrds I don't think less than 12 x gives enough precision.
