I was gonna ask if I could send some tins for sorting as wellSo only half a job then
What happened about different sizes
BTW, can I get your address so I can post about x10 tins to you to sort for me.

the Daily hi thread
I washed, lubed and weighed 1000 H&N Baracuda 8’s for BR

I think think the notion that dieseling is only specific to springers is because springers have grease inside to lube the piston and spring and the grease can transfer to the compression chamber.
However, if you are lubing the pellets then this brings dieseling into play for PCP’s as well. I suppose it depends on how much lube and what type you are using.
There are plenty of YT vids regarding dieseling (typically American) and the effect is quite dramatic, erratic, and rather iffy. Not good for the internals of the rifle over the long term.
What is the thought behind lubing pellets for improved accuracy ?

This was 2024 mind. So baras might have changed.
My ocd at its height and sunday rain.
I had 3 tins of baras from various manufacturing times of the year. I weighted 100 from each. The variation was 4 tight rows. Tried the same with jsbs heavies had rows of 8 and quite the extreme. Out of 300 one bara was rejected for slight damage.
As I weighted each one I had a control pellet to make sure scales stayed calibrated. So 600 weighed.
The 3 batches created made no difference at 25m BR over 2 months one per week card so gave up. Other factors had more baring. e.g. I felt baras to be relatively wind sensitive. Used a Daystate Revere.
I also sized some with 4.50 and 4.52 sizers. Poor results.
Now if I was at the Olympics going for gold I would just do it to find the 1 in 300 bad pellet. I'd also do tests for a new pellet type to see their quality.

Did the wash (ultrasonic cleaner), sort, weigh and lube a couple of times. In the end I decided that with my aged eyes there was no difference. I still lube though with LT1 as it does help a little and as I have 6 friggin' bottles of the stuff

With regards to dieseling, a light lube
ie roll around in a cloth or bag shouldnt cause any issues, dieseling is only going to occur when something gets behind/in the skirt and then compressed along with the air by the piston surely

..but then what is the thinking behind lubing for improved accuracy/consistency anyway ?

I tried it once -- I had been seduced by the claims in the advertising
.. but how do you guarantee that each pellet receives exactly the same amount of lube? . It can't be done. I also did the much heralded "pellet pampering"
And then you get that "Ureka" moment when you realise that -- apart from discarding the obviously damaged ones -- there is no difference between "pellet pampering" and taking them straight from the tin.
But, hey, it's a hobby..... and hobbies can be as time-consuming as we want them to be.

I tend to agree, but even so there must be some reasoning behind lubing the sorted pellets yet nobody seems to be able to identify it.I tried it once -- I had been seduced by the claims in the advertising
I also did the much heralded "pellet pampering". . It can become an obsession if you're not careful.

Perhaps it’s a pointless exercise but it makes you feel like you are doing something useful and therefore more psychological than physically real. A sort of placebo activity.
Sorting and discarding flyers has an obvious benefit, but lubing ?

I dont think its proven for any improved accuracy?
a light oil was more of a storage thing in my eyes, perhaps a hang over from when pellets were not as good quality and corrosion could creep in to old tins?
From the Daystate Red Wolf handbook:
BARREL CLEANING
For optimum performance, the barrel should be periodically cleaned with a barrel cleaning solution recommended for air rifles, or a pellet lubricant. Daystate also advises the use of a lubricant applied to the pellets to reduce lead deposits and maintain the barrel. Frequency of cleaning depends on the pellet type used and the individual barrel; for general guidance, the barrel should be cleaned after every 500 shots. (My emphasis on the relevant sentence)
Well, somebody advises it!

Thanks for that Tony. It seems it is more for general rifle maintenance rather than pellet accuracy.
Although don’t people keep talking about getting a barrel ‘leaded up’ from new to get better accuracy/consistency i.e. a lead coating gives a good low friction seal to the pellet ? Maybe best to leave that for another thread
.
In a spring gun you're compressing air which causes it to heat up, in a pcp the air is compressed already and expands as it is released which causes it to get colder. In the spring gun you have the conditions you find in a diesel engine although not controlled in any way so every shot will be affected differently.
At one time, may well have been the 70s there was a version of the HW35 (if I remember correctly) which had some form of oil? injection which was supposed to give consistent dieselling but I have never seen one and I doubt many were ever sold in the UK.

Yup, regular barrel cleaning maintains accuracy and lot more than playing with the pellets.

I recently did my chrono checks on my air rifles and pistols the two SSP that I use for 10 meter target Anschutz 2001 Superair and Walther LG 210 gave me these very consistent results, no pellets washed weighed or lubed.There is no point in weighing to more than 0.1gn as in reality your scales, your gun, and yourself don't function to that level anyway. In the real world more precision just becomes a technical footnote and does not alter the actual results beyond a certain point as you don't get any more accurate than accurate if that makes sense?
The figures your using from the above is the equivalent of around 1fps, as a full 0.1gn on a sub 12fpe rifle is approximately 5fps.
So given that - do you really think you shoot to within 1fps, or can tell the difference shot to shot of the 5fps I use? From a POI point of view you can't even measure a 5fps difference @25m let alone shoot to it
Save yourself some time and effort and just weight to 0.1gn accuracy, it's easily enough for what we do, and ultimately weighing pellets is about getting rid of the anomalous ones that throw fliers rather than having every pellet an identical weight, because when they are so close t the same weight they are effectively the same for us

I have gone down the weigh , wash , lube road before and found that apart from checking for deformation, until you yourself are consistent in your stance , head , eye positioning , the most important thing is a consistent air rifle or pistol.

I hadn’t thought of that regarding PCP’s. All the compression and heating happens when filling the bottle, not on demand with each shot.
Everyday is a school day, as they say. Thank you.
