rws pellets

[remyd 68]

rws super field's, what's the difference between the 4.51 head size and the 4.52 head size? other than the size lol! what's the point in making both?

cheers remyd

Some barrels just prefer a tighter fitting pellet mate.

 

I suppose a wider pellet will make a good seal too with the skirt being pushed into the rifling easier.

 

Also some barrels are not machined to the standards of the top name barrel makers so this could also be a factor buddy, but I don’t have the 100% gospel answer.

 

Maybe Matt Hooks will be along soon, he’s into all this type of stuff and will probably know better than anyone.

cheers si will give them both a try when my new gun arrives . just a quick 1 zini thinking about the hawke sidewinder tac 30 4-16x42 mildot ret from blackpool air rifles but they do the 4-16x50 mildot ret whats the difference? is the x50 the bigger half mildot ret thats true on x20 mag ? dont want to order it to find out its the wrong 1 cheers again remyd

nothing can be made 100 percent the same so when you make somthing there has to be a tolerance + or - .So all the pellets will work 551,552,553,554 in a 22 barrel but some may work better than others.the difference in size .03 OF A MM .

The first two numbers 4-16 is the Zoom ratio ie 4times larger to 16 times larger in the view. The last number is the diameter of the front (Objective) lens. The larger the front lens the more light it gathers so the better/clearer/brighter the image is. More useful for low light/night shooting. Go for the larger lens

Sorry buddy i have only just seen this post.

 

As Tony said pal, cheers Tony buddy .

 

Mine is the Hawke Sidewinder 30 4-16 x 50 mm mildot AO IR scope and the qualityof the optics is staggering.

 

What i like about it is the mildot reticle inside is very thin and it allows you to pick a very small point on a very small target (as in them match sticks heads i shot) at a fair distance where some other models have a fatter reticle which isnt so easy to pick up small objects with.

 

The scope you bought (Mamba) is also a brilliant scope and i used one quite alot over the summer when filming with Phils .25 Ultra. I think out of al the scope that ive used the 3 scopes that i have found to be the best are:

 

The Hawke sidewinder - quality of the optics and glass

 

Mamba - As above, and both will take some beating for a air rifle scope. Highlighted before someone mentions Zeiss, Swarovski and other really good expensive scopes that are used more on full bore rifles.

 

Tasco 6-24x50 AO IR - Best bugget scope i ever used. Shot quite abit with my old one in Catterick.

 

My next scope for the new rifle im getting is a Hawke sidewinder Tac 30 4.5-14x42 IR SF.

 

That will sit nicely on the Theoben MFR .

The RWS Superfield pellets are the exact same as FX, JSB Exact and Air arms Field. Shop around you'll be surprised just how much difference there is between the "brands".

 

The sizing of the pellets comes down to the fit of the barrels, as I'm sure we all know barrel making is an art not a science, every single barrel is different not just batch to batch but the next one off the line! BSA barrels often prefer larger head sizes as they have quite deep rifling, the larger pellets make a better seal in the deeper grooves providing better stabilisation as the air blows into the rifling. AA or LW barrels do not have such deep groves so they often like the slightly smaller sizes.

 

It's a very tricky thing to explain, you could do dissertations on it! And that's before getting into the maths!

 

I've just bought that scope Si!

We have alread proven that FX and Air Arms Fields are not the same time and time again!

I did this a few years ago when I first came across FX after a local RFD told me they were identicle. I put them down my S200 and they grouped about 3mm wider than the AAF's and the POI was an inch or so out both in Elevation and Windage.

I stood them side by side with AAF's and photographed them and put the photo up on here somewhere showing the diferances.

I've been and done a search to link back to it for you, but the search does not go that far back, so I'll draw your attention to the Ballistic Coefficiants of the RWS Superfields being 0.0283 in .22 cal @15.9grain where as the AAF's BC is 0.0310 in .22 cal yet they are also 15.9 grain so although they do look very similar, they are in fact very different

I have not been able to find the BC of the FX pellets and have not as yet done the testing to actually work it out.

Si did a very good video presentation on how to work out the BC's between different brands so the data could be put into CGP & BRC for better more accurate modelling using these programs.

Did you take into account the batch to batch variances from JSB? Have a look at an "old" batch and a new one of JSB pellets, the Exact Heavies are VERY different now from the way they were last year, both in the weight and the internal moulding. If anyones got some "old" JSB EH's you will see a very clear difference. Telling the diffferences on JSB, AAf's and FX can be done but they do come from the same factory.

 

Not starting a debate, just my opinion.

Hi Phil,

 

Yeah your bang on with the factory, most of the 'branded' pellets do indeed come from the same factory

I've not done any recent comparison, I've just been through my shooting gear looking for some rws Superfields, but none left now, still got some AA & FX ones left hoping to get a new batch of each in a week or so

Daft question Tony: Is the higher the BC figure the better?

No such thing as a daft question Elliot (unless it's one you dont ask).

In short; The higher the BC the more the more aerodynamic the projectile, the flatter the trajectory and the further it will fly.

Great, thanks mate

Unfortunately the Webley Mosquito Express pellets my HW100 prefers have now been discontinued! Just bought some Superdomes in .22 to see how they fair. Really cheap at £7.60 per tin for 500. The Mozzies were £7.40 for 200!

 

I'm led to believe the JSB Exact Express are very similar to the mozzies and intershoot have them at £12.00 per tin (500) which is still expensive but cheaper than the mozzies which would have been £18.50 for the same amount!
