Guest cookoff013 Posted July 2, 2018 Report Share Posted July 2, 2018 without being to over generalised, it is too quick a burn rate for any decent speed 20 gauge shell. if you did find any data it probably would be 21g loads and "not fast." there are loads around for AS and 20gauge, the AS and csb5 are quite similar in performance / burnrate. if you can wait, get the right powder. if you cant, ask everywhere for solid data, not guess work. dont jump the gun with this Quote Link to comment Share on other sites More sharing options...

The only thing is that using a weak primer (cx50) you could probably push to 23g but will be slower than average Quote Link to comment Share on other sites More sharing options...
Guest cookoff013 Posted July 3, 2018 Report Share Posted July 3, 2018 there was a great thread in another reloading forum where reddot powder was used to create some absolutely economic 20gauge reloads. all pressure tested and anaylsed. the key with this subject of using a powder that is too fast is to get the load tested. thats the only way to make sure.

Continental Shooter Posted July 3, 2018 Report Share Posted July 3, 2018 You're right, anything and everything can be done....even 28 g with Tecna is achievable - even though the minimum for the powder is 30 g in 20 bore- but for me the most important think is the PSP test: - pressure: Is it right for the load (i.e. 850 bar for 21 g is way too high) - speed: have i got enough to generate a clean kill at the distance i want to shot at - pattern: do i put enough pellets in the circle to generate a clean kill at the distance i shoot at as you know ... all my loads are proofed or i wouldn't give it out ; the only reason why i didn't post the recipe with 23 g is because i can't find the certificates ?

Guest cookoff013 Posted July 4, 2018 Report Share Posted July 4, 2018 thats pretty simple, its not without criticism, but its fair. my criteria is essentially clean small efficient. there is maxam recipe for 28 gauge with csb5 and its not too far from a starting point in 20gauge. but i certainly would advise having a good think and test at a reputable lab.

That's the load that was on fes site cheap cheerful brakes clays sometimes ? yes this is the kind of data that uses a relatively fast powder in smaller gauge. as there is no pressure data here, i certainly would consider this as maximum and is about right for the gauge and hull used. here is a tip, with such a small powder charge, any change such as reduction would severely affect speed, and of course an increase would do the same, dramatically increase pressures, that you cant evaluate when shooting in a sporter at clays. nb. good luck-looks like a cute load. and for the 24mm height, would be 2x 12mm, that would add an extra £25 / 1000 but you would have saved £30 in powder and shot, (21g).

spot on Posted July 5, 2018 Author Report Share Posted July 5, 2018 thought there was ..I noticed eley hawk load with csb 5 as well cheers for that Quote Link to comment Share on other sites More sharing options...
spot on Posted July 5, 2018 Author Report Share Posted July 5, 2018 just got a beam scale "didn't trust the electric scale I use for weighing coins" checked my powder throw weight 13.8 grains not too bad ..the shot bushing at 7/8 throws 22.5 grms at seven and a half size ..fettled the bush to throw a tad below 20 grms now..just to be on the safe side..all else is as per PESTCONROL,s post..i did shoot a 40 bird sporting charity event several weeks ago using 14 grns behind 22.grms all seemed ok but to err on the safe side I will use the "modified" loading until the csb3 arrives ..I think the shot bushing was throwing over weight because the smaller shot size provided more bulk ie less airspace surrounding the pellets than would have been if larger shot were used Quote Link to comment Share on other sites More sharing options...
Guest cookoff013 Posted July 5, 2018 Report Share Posted July 5, 2018 thats really good to know- the powder drops are fine. the 13.8 is acceptable as 14, as they do drift around. Quote Link to comment Share on other sites More sharing options...
Guest cookoff013 Posted July 5, 2018 Report Share Posted July 5, 2018 nb i think this is a 70mm hull. and your 7/8oz lead shot bushing is dropping light, i would have expected 25grams atleast. if the load work well it is slightly more economic on powder, 1 kg would do more than 1100shells.

spot on Posted July 7, 2018 Author Report Share Posted July 7, 2018 obtained a couple of ct 20s last night according to the eley specs ct20 21grm felt is powered by csb5 ,,broke 2 down this morning the charges weighed in at 14.5+14.6 so my load aint that far out ..tried 2 over the barley yesterday ..first as a scarer ,,2nd at a cushtie …....result it really made it fly a bit faster I am sure it did Quote Link to comment Share on other sites More sharing options...
