Pellet size

Hi everyone, I'm quite new to airgunning & I'm currently dabbling with washing, weighing, lubing & sizing pellets.
I'm looking for an accurate .177 4.52 mm sizing tool does anyone have any suggestions ?
I have a daystate redwolf & it likes jsb exact 4.52 pellets.
Ps: does all this guff really make a difference?

You’ll get a load of answers on whether it’s worth it - personally I’d see little benefit in lubing but think sizing and weighing can help you squeeze down the group sizes at longer range, if the rest of your equipment is bang on and you’re shooting off a rest.

I've never bothered washing, weighing, lubing or measuring pellets.

You need first to decide what level you want to shoot at,and what disciplines you are shooting. If you fancy yourself as a top br shooter you will have to weigh and sort and clean them pellets to even stand a chance of a trophy. For most other disciplines a quick inspection and maybe a weigh once you have found a decent batch is all that is needed.
The head size on the tin is bs. If you measure some accurately you will notice many are under the quoted size.
My advice.. the pellet you have been using to good effect, buy as many as you can of the same batch (check the code on the tin) and go shoot.

Ok, I'm taking a deep breath because it's a very long answer that was well covered on the old forum, but it's not on this one yet.

I'm not going to go into it all as it's several articles and tests on it's own, but basically you have three schools of thought for three differently minded shooters.

1. Your plinker/range jockey or hunter will have the opinion that life is too short for all this rubbish, and pellets straight out the tin are all that you need, they don't measure tight groups, that's for zeroing and then you go for it

2. Those into BR on a more serious level will know for a fact that little things make a big difference to scores, so they will be all for this, but only or as much as they can see the results, which in most cases are a few mms @ 25m and less fliers (like 10mms ), but that makes the difference from a 9 to a 10 and can double the number of Xs, so for BR it's a definite thing

3. Lastly you have the HFT/FT comp guys, they shoot outside in the wind and rain, so the couple of mm difference you can gain in accuracy is quickly lost under real world conditions, so they tent to try and get the best batch numbers and stick with them - although the guys at the very top will also go down the BR route and spent time on their pellets

So that's a quick answer without all the science, as the site grows and we recover old data there will be more on this transferred over.

I posted a review of the TR Robb pellet sizer in the old forum. It's adjustable and needs to be calibrated, which is easy enough using drill shanks.

The dimensions for my .177 sizer (they may vary for different sizers in same calibre) are as follows:
Taper ratio 1:50 (a standard metric taper)
Maximum dimension 4.9mm
Minimum dimension 4.3mm
Screw pitch 0.6mm

These dimensions give a size adjustment of 0.02mm for 1mm adjustment of the screw, or 0.012mm for a single turn of the screw.

I shoot mainly JSB pellets and I found it was effective for some batches which guns didn't particularly like but made no clear difference to batches which already worked very well. I posted picture of group sizes showing improvements.

I don't size or weigh pellets for general use, only when fine tuning a rifle so I've done as much as I can to eliminate variations caused by the pellets. I don't wash or lube pellets... don't see much point in washing off the lubrication from manufacture.

The only way to know if it makes a difference is to try it yourself. There's the psychological aspect: if it gives you confidence and you believe it makes a difference, it probably will. If you make the pellets undersized it definitely won't!

Thanks to everyone for your advise.
I forgot to mention I've started Hft shooting and the reason for all the phaffing is to zero my scope & find the power sweet spot of my rifle.

I like the idea of finding a batch that shoots well, then buy a load of them.
