Medium vs. Heavy Pellets .177 test

[19powell90 89]

After purchasing some bisley mags i decided to do an accuracy test against the well known AA Fields.

 

As i thought that the heavier pellet would be better for hunting, is this true???

 

I did a 10 shot test with each pellet using my s410 at about 15 meters.

 

Please bare in mind that my scope is zeroed with the AA Fields which you will notice on the pics.

 

On both pellets i aimed for the white dot in the center.

 

 

 

group size 13.5mm

 

 

group size 11mm

 

 

as you can see the AA's are a little bit more accurate but only by 2.5mm

 

i will upload some more tests at different distances

 

 

 

 

hope you like

yeah i know it is. im going to do some longer distance tests and see how that goes.

 

i actually bought some h&n sample pellets of ebay but they woudlnt fit in my rifle (very strange) so i sent them back and asked for some bisley mags.

 

my local shop sells them but i dont know how much.

 

just try ebay and shops online.

Nice groups

 

I had a similar drop in POI when I ran the Biz Mags through my baby. Again my Zero was with AAF's (only difference was its .22)

Also I notice that your BizMag group was (bulk of) to the left as was mine

 

A heavier pellet retains nore energy down range than a lighter pellet, BUT as I am going to tell you, most others will agree here.

 

If you can put a pellet in the kill zone, the quarry is going to die quickly and it's not down to the weight, cal or retained energy of the pellet its where you put it

yeah thats what i thought.

 

 

i will test out some longer distances and see how it goes.

 

i might try the 4.51 AA's to see if it will tighten the groups up even more

i think they are both good pellet,although my first choice would be bisley mags

i noticed the aa pellets where 4.52 ,what size was the bisleys mag?

Im not 100% on this but i only think they come in one size which is 4.51

Both brands of pellets are very good pellets and group really well in my Ultra but it was set up for Bisley Magnums as that's what Tench found to be the best in that particular barrel.

 

Just remember mate that your mate could have the same rifle as you in the same calibre with a serial number only 1 away from yours and the results could be totally the other way around as every barrel is different slightly.

 

You now do that same test in the wind mate and I bet I will tell you which pellet will group better.

 

Thanks for putting in the time on the test though buddy.

 

Great post

yeah will do some more tests.

 

do you know if they come in different sizes e.g. 4.51/4.52?

[zini 1,939]

Yes there are different sizes mate.

[19powell90 89]

Yes there are different sizes mate.

ok thanks

 

 

also i was looking at getting my s410 regged, so does he test which pellet is better?

 

and once it has been regged do you need to use only one kind of pellet?

 

just some info needed really

 

thanks

Hi Scott,

 

Mr Howarth will set your rifle up if he tunes it to the best pellet for it so you get the best out of it mate.

 

Not sure about the reg bit pal I think he just sets it up on a good pellet so that its doing around 11.7 -11.8 ft/lb.

 

Better off giving him a call buddy as I’m thick when it comes to rifle internals.

 

No you still can use any other pellet you want buddy.

did some chrono testing today with the aa's and bisley mags

 

i did shots and my averages are:

 

AA FIELDS

 

1-10 11.28ft/lb - 777fps

11-20 11.34ft/lb - 779fps

21-30 11.32ft/lb - 776fps

31-40 11.42ft/lb - 782fps

41-50 11.40ft/lb - 781fps

51-60 11.40ft/lb - 781fps

61-70 11.36ft/lb - 780fps

71- 11.22ft/lb - 775fps

 

BISLEY MAGS

 

I only did 10 as these were low and my aa s410 likes the aa's more so far.

 

1-10 10.62ft/lb - 674fps

I think you may be missing another point. The heavier pellets drop alot faster than the medium to light ones. If you are shooting an unknown range, as in a hunting situation, then you have more chance of not being accurate with the heavier pellet due to its trajectory. Have a go with Bisley Long Range golds if you can get some. They are very light, but a superb pellet in the field.I first used Magnums many years ago when i was still shooting an Airporter and i wasn't particularlly taken by them then.

I fully agree with Phantom when he states that its where the pellet hits rather than the 'energy'. Over the years i have walked out with lads that have boldly stated that 'such and such' a pellet was no good for feather etc. Hit them in the right place and they go down. We all like different things, personally i like a light, flat-flying pellet that i know doesnt need too much of a hold over at range. Just a thought.....JD

Just what i am finding with the lighter .22 falcon pellets some of the heavy ones (mags inc) are just far to loopy.I know its .177 thread but anyone wanting a lighter pellet in .22 try the falcons.
