I have a DIANA #48.. .177 fixed barrel..


I also have a HW #77..

. if I want to do a "neck-shot"
.. on a cow-bird at 20 yds. ---

.. give me the Diana..

...every time...

..and when it comes to the chrony...

. Diana doesn't lie.....


.. HW ??
.. well...
...I don't know what kinda lightweight pellets ther
..shooting..
.. but I get about 100 fps. less than they do...

... that's "show biz"

Actually both Diana and HW overstate the velocity of a few models. On the other hand, some are rated quite accurately, and some even under-rated from both manufacturers.

I must say that one of my most accurate AG's is my HW77k in .22cal, 0.3" five shot groups @ 30yds. This is the average of twelve 5 shot groups shot from a rest with a match front sight and diopter rear, no scope, no magnification used. My 77k does about 640fps with 16gr ammo and tops out at about 700fps with the lightest pellets I have(14gr), so really it's only about 50fps shy of the ratings put on it. Besides, velocity ratings are the last thing you should consider when buying an airgun, energy is a much more accurate way of judging the power of a gun.

You're right.
.. I was being a bit "unkind" to HW.
I was a bit upset due to the fact that when I first chrony'd the 77 with 16 grain "exacts", I got an average of 630.8 fps. which seemed a long way short of their 750 fps. claim.
I got 1011 fps. (.177) average with my Diana 48, which seemed pretty close to their claim of 1056 fps.
..although today the Diana averaged 955 fps. - same ammo, same set-up etc. etc. - change in humidity?

.. The Hw 77 after I got it sighted in - the first 5-shot group @ 12 yds. was .280" - the second group was .240"
.. and is very consistant.
I have no complaints, - this is with a scope, 'cause my eyesight is such now, that I couldn't hit my back fence with any sort of iron-sights.
I remember when I did a .75" - 5-shot group at 300 yds. with a .270 Winchester - peep sights -- those days are gone forever.
..I had eyes then.
..
..and I agree, it's the hitting power ( energy ) on target that counts.

..and without having any stats. - I'm sure at 100 feet.. my .22 HW 77 is going to hit a lot harder than the Diana 48 in .177 .
Am I correct about that, ? or not ?

.. Best group with the Diana so far, is a 10-shot effort, measures .203" - like that one. )
