larger pellet always better?

[hwtyger]

it's said that a bored barrel needs a slightly larger pellet to be effective
would that mean a 4.51 is always better than a 4.50?

[gary_cooper]

No. Don't be silly

[Bulsaye]

depends on what the TRUE bore of the barrel is. They aren't all exactly the same you know. Many folks assume they are-- they are not. You need to try different pellets and use what shoots best in YOUR gun. RB

Jon,

Them Daystates were pretty good - thanks for that!

What happened to that theory that the blast of air the pellet gets up its ar5e causes its skirt to expand and grip the rifling? Then .01 of a mm would not make a bit of difference surely. Is that just a lot of old tosh or what? Or are pellets not made out of pure soft lead like in the 'good olde days'?

Cheers Dave,

my prosport loved 'em too, so no suprise the HC does...

All you need now is that silencer <img src="http://jsramsbottom.co.uk/bbs/e/icon_wink.gif" alt="Wink" width="15" height="15"><!--graemlin:-->

Right on the tail, but the sizing refers to head size - although I'm a tad sceptical myself too...

I find it does make a bit of a difference, but not necessarily the bigger the better.
My Mk3 FAC prefers .51 Daystates and AA Fields and Barcuda Match to .52s. The difference is almost indistinguishable but it is there. Certainly the .51s are about 10 fps quicker than the .52s, which is quite a bit.
Best to experiment, it seems <img src="http://jsramsbottom.co.uk/bbs/e/icon_smile.gif" alt="Smile" width="15" height="15"><!--graemlin:-->

i tried .52's(normally use .51's) in my tx and at 30 yards it was shooting 2inchs low

You sure that wasn't just your cr@p shooting Nick?

Very interesting article here.

It must be surely a joke that certain pellet manufacturers are advertising .177s as 4.50, 4.51 and 4.52mm? After all, the amount of malformed pellets that simply have to be discarded from a tin of Air Arms Field (for example) makes a mockery of this alleged accuracy in pellet measurement?
I would not be surprised if the last digit in 4.5X is where X represents the number of the die that made the pellet (much like Crosman Premiers). After all, why stop at a 0.02mm increase?
4.59s anybody?

I took a tin of each, 4.51 & 4.52 Daystate FTs, and tried them with my Pro Target and my Rapid 17.

I was shooting indoors with the guns rested.

In the PT the 52s had a higher POI at 25yds than the 51s but grouped slightly tighter with 51s.

The Rapid gave tighter groups with 52s.

I'm going to do more testing next week.

The differences are not massive but the frequency of flyers is lower in the preferred size.

Looking at the theories; even if the skirts end up the same size they still have to be expanded to get to their final shape.
This takes time and energy, different time and energy for different sizes.
That could have an effect on performance.
