Gents a little help please. I am new to reloading and would like to make a 20 ga 28gram fibre wad load running about 1450 fps does anyone have any load data. I have trawled all the websites I can find but can't find this load using a fibre wad thanks in advance

Bout 200fps too fast for a 20 28g load as pressure will be high, at 1250 with a progressive powder without going for 1450.

 

Not saying couldn't be done but unless you are an experienced reloader backed up by proper testing, you need to look at 1200 to 1250fps.

The fastest you can send 437.5 grains of Lead in this case Nicel plated high antamony Lead size 5 . is 1320fps@ 9foot.

The load is within the 20 bore pressure spectrum SAMI i dont tend to use CPIU too restrictive.

There is potential for a full on 1400fps load of 1 oz, but even high antamony shot and modern powders put the hulls and wads under strain in the 20 which tends to be the limiting factor, you can get around this with the 3 inch fiocchi hull which is the biggest capacity hull in the 20 which offers lower pressures you could use for speed.

But for lead 1oz this is as good as it gets on speed PRACTICALY.

 

Hull use a RIO the SAGAS are the same and in a 70mm they offermor volume and are stroung in the hull body giving good strong crimps from once fired hulls and thus uniform balistics.

The base was section of the hull is the achilees heal of the RIO..SAGA it WILL split when the going gets tough be warned, It is not my opinion either its well documented accross the WWW this Base was Trouble in Rios just google it for clear evidence of this if you dont believe me, I have seen it too often for this to be a moot point.

 

Lead is soft eve n hard antamony Soft raises pressure ultimately, initialy not so much but ulltimately it does.

But in our favour less volume in the shot charge IE more dense IE LEAD is good so mit counter ballances the Softness aspect.

Its no good having a fast load if its pattern is dire, it needs to work as good as you can make it work.

High internal pressures and associated deformity need to be tackled as best you can, obviously buffering is needed, and again this bumps up pressure thus needing reduced powder charges and this again is an enemy of our goal here ,, SPEED.

 

Wads And You are talking fibre here, now i like fibre i like how when in a well developed load the patterns can be very reliable even and not as centraly dense over a broader area of ranges than typical plaswads can be at times, none of these latter coments are set in stone obviously but how i view fibre wad loads.

 

Powder with lead ytou are trappoed you can not use a very progressive powder like steel in big charges because with these pressure will be a problem too soon for high speed, and you can not use a Bulky high energey powder like lil gun because the nature of lead defornity pressure etc, and the sheer volume of the case taken up by such powder and the accompanying pressure increase, it destroys its own purpose, a bit like say 2400 in the old ten loads did compared to the faster blue dot being just fine.

So we need a medium to low bulk style modern progressive i went with good ols A steel lot 12.

Now primer the RIO hulls sagas too use Well RIO primers, :lol: the primer pockets on these hulls are bigger than std 209 type primers like cx2000s win 209s etc,

Now the RIO G1000 primers are available over here and apart from obviously fitting the hulls they are hotter in the briscance aspect and with A steel this is a huge Pluss, so the primer choice although limited as worked out great for this load.

 

So hull RIO saga 70MM.

Primer Rio G 1000

Powder A steel ?2 grains

Wads Inverted card cup 5mm soft white felt Top card ^mm fibre nitro Thin 1,,,, 3mm cork

437.5 grain of Hard nicel high antamony lead Italian made.

16.5 grains of Std winchester Buffer. tap it in well.

Compress to 40lbs and nornal crimp close.

9854PSI

1320fps @ 9 foot.

 

If you are determined to 1 oz of lead over 1400FPS it can be done and i would use the biggest internal 3 inch hull the fiocchi mid to late 30s grains of LIL gun and pay attention to details to keep your pressures down, its not going to be a walk uin the park for you with lead but it is dooable if it still patterns is another thing because it will be well over 11000psi and in such a charge weight as 1 oz in that bore.... Well its going to be interesting let me put it like that.

Now a change of shot say go to copper you can comfortably get well over 1400 fps in that weight load in a 20, its the lead thats leting you down.

Thanks lads is it best to start slower then?

Cook it's for lead fibre wad power and primer ect are what I was after for suggestions and more importantly the load data

Yeah.

 

Forget the speed. Just go with high quality components normal loads. Forget 1450fps.

I doubt if you could bodge a load it would end up 3".

I know what you want.

Steel is the name of a powder.

One other powder could perhaps be of use but doubt it would quite match lilgun, is Vectan SP3 . Never used it but there used to be some Fast 20 bores sure they were lead on The danish reloading forums . Not the old Patrontest the new one that started after it went. take a look on there if you can find it.

Well Tony I thank you very much I will heed the advice and knock up some loads I want to use like 28gram lead in 6 and 7 shot but I think I will look at 1250 fgs as the max. I have the clay and game data sheets for 20ga but don't think they use fibre wads is it safe to exchange the wad for fibre?

Well theoreticaly yes but it wont perform the same you need some A steel and do the above load its the closest your going to get to your criteria and it does work fine, i used this load Slightly modified with a plastic gas check, and ITM shot before it disapeared.

Just forget about silly speeds, most cartridges come nowhere near and have no need to either. I have a number of proofed 20g loads on the FES website and the fourth 20gauge load on there should suit you just fine at 1240 fps.

As above,

Sits has given some good data there.
