ag12g Posted May 30, 2017 Report Share Posted May 30, 2017 hi all, has anyone loaded a 28g lead shot fibre wad in 70mm case with 1.6g of csb5. Quote Link to comment Share on other sites More sharing options...
rbrowning2 Posted May 30, 2017 Report Share Posted May 30, 2017 No and I do not think I would want to where did you get that load data from? looks like a brown pants job to me. Quote Link to comment Share on other sites More sharing options...
Guest cookoff013 Posted May 30, 2017 Report Share Posted May 30, 2017 No and I do not think I would want to where did you get that load data from? looks like a brown pants job to me. maybe, maybe not. dont forget there is a 2 tier system in place in cip / european member states, where 740 and 1050bar are the ptmax. however without actual pressure figures, it could be a "brown pants" if not properly researched. hi all, has anyone loaded a 28g lead shot fibre wad in 70mm case with 1.6g of csb5. no, i`m going to put some csb5 through a pressure barrel before the end of the year. should be some weirdo stuff too. 3" 25gram steel HP / 1050bar.

rbrowning2 Posted May 30, 2017 Report Share Posted May 30, 2017 Is 2.3/4" not limited to 740bar CIP? Max I have seen for csb5 in 12ga 70mm 28gm lead, is certainly significantly less than 1.6grams. Quote Link to comment Share on other sites More sharing options...

Max I have seen for csb5 in 12ga 70mm 28gm lead, is certainly significantly less than 1.6grams. no, you can get 1050bar 70mm loads. http://www.fiocchiuk.com/site/index.php?pag=790&linea=2&titolo_prod=High%20Performance http://www.fiocchiuk.com/site/index.php?pag=790&linea=2&titolo_prod=High%20Performance&prod=691 800 bar is above the 740 bar standard limit. i believe its to load upto the 740 bar limit with a wiggle on the pressure variation.

ag12g Posted May 30, 2017 Author Report Share Posted May 30, 2017 hi all stripped down a misfired clay shell which maxam own, the powder in it was identical in colour and shape as csb5 and weighed in at 1.6grams anyone with any info would be good.

Ant I think you are playing a dangerous game see http://www.maxamcomponents.com/en/outdoorsbrand/componentes/products/powders Lots of their powders are grey in colour same dimension but different density. Get reliable load data guessing a powders as has been discussed several times on PW is not without risk. Quote Link to comment Share on other sites More sharing options...
db135 Posted May 30, 2017 Report Share Posted May 30, 2017 I use 1.4gramm cb5s with with 22mm fiber wad 4mm over shot card with 28gramm 7.5 shot in used 70mm casing with cheddit primers works fine Carnt remember what the number on the powder bushing on my Lee load all but can check Quote Link to comment Share on other sites More sharing options...
arm3000gt Posted May 30, 2017 Report Share Posted May 30, 2017 1.6 gram does seem high.The load I have used is 1.36 gram and worked fine on clays the other day. I've not seen a 28gram load with as much as 1.6 grams of csb5 when I was looking. Quote Link to comment Share on other sites More sharing options...
ag12g Posted May 31, 2017 Author Report Share Posted May 31, 2017 db135- that's very similar to what I load just use a rio primer I'm finding that its a good skeet shell and ok sporting shell just seems anything past 25yards is either a chip or a miss then have to reach for the production cartridge to do the job, this is why I posted the topic about the 1.6gram weight as the suggested loads seem a bit lame Quote Link to comment Share on other sites More sharing options...
matone Posted May 31, 2017 Report Share Posted May 31, 2017 Surely a .2 gram increase is a big jump in powder charge though Quote Link to comment Share on other sites More sharing options...
ag12g Posted May 31, 2017 Author Report Share Posted May 31, 2017 totally agree with matone this is why I'm asking the questions, wont be loading any without them being proven first Quote Link to comment Share on other sites More sharing options...
Continental Shooter Posted May 31, 2017 Report Share Posted May 31, 2017 right so: Cheddite CX2000 1,35 grams of powder, then a Gualandi SG25 wad and 28 grams of lead; i proofed this and returned 406 m/s and 640 bar you can probably go fibre and 1,4 and have the same results; could even push it to 1,43/1,45 if using RTO; i've even seen it loaded with 1,45 x 28 with Gualandi SG25 but that was a very progressive batch of powder we had; in fact it was suitable for 32 gr lead whic hthe new batches will not gladly take (i think the max is 30 gr these days) Also, i will never stress enough: you should never copy factory loads! Big manufacturers have made to order powders to suit their requirements and the retail version is most likely nothing to do with the factory one. so, by using the same recipe you will most likely be overpressure at best. An addition of 0.2 grams powder can give you anything between 100 and 150 bar pressure increase depending on powders (with fast burning powder being more affected) Quote Link to comment Share on other sites More sharing options...
rbrowning2 Posted May 31, 2017 Report Share Posted May 31, 2017 Couple of other points, are you getting a good quality crimp as that effects the performance of the powder and have you pattern tested the cartridges together with the commercial ones?

ag12g Posted May 31, 2017 Author Report Share Posted May 31, 2017 have been complemented many times on my crimps and finishing of homeloads very near to a factory finish once they have been spun, as for patterning I usally judge them on the kills I get on DTL, first barrel kills seem ok ish second barrel kills are chips at best so I tend to use a factory shell in second barrel, I consider myself a competent shot and have been shooting clays for the past 20 years and like most people have tried all sorts of makes of cartridges in fibre/ plastic different shot size etc.Is it possible to produce a competitive clay load ?? or am I after something I cant produce with the available components, have been reloading for 2years and used my homeloads in 2 x 100 sporting bird comps for the first time last month and my scores jumped from A class to C class scores went back to production cart scores back A class, would like nothing more than to produce a competitive shell in my garage even if the I just broke even on the cost Quote Link to comment Share on other sites More sharing options...

Patterns were not as tight as premium trap loads.back then shot had low antimony contents.I tried changing wads ' powder ,Then I used shot from a Remington RXP trap load.The reload was tighter than the Remington .The key is shot hardness.Dipper.

ag12g Posted May 31, 2017 Author Report Share Posted May 31, 2017 the shot is fine because that's what I use in my 410 homeloads and get good results with it, don't think going heavier is the answer on the 12 the powder in my opinion is struggling to push 28g, maybe just have to settle for skeet shell Quote Link to comment Share on other sites More sharing options...
rbrowning2 Posted May 31, 2017 Report Share Posted May 31, 2017 Csb5 is used in a lot of 28gm 12ga loads produced by the prolific maxam family of cartridge manufactures and as continental shooter has shown 406 m/s is no slow coach, accepting it is a plastic wad. The shot will not suddenly stop at 25yards it sounds more like a pattern issue but are you able to chronograph your loads? Or get c&g or the proof house to test them then you will know for certain how they perform in both velocity and pressure. Or try a plastic obturator in place of the overpower card to see if it that helps (but use plastic wad load data). Is your gun back bored?

ag12g Posted May 31, 2017 Author Report Share Posted May 31, 2017 yes it is back bored and fixed choke 1/2 and 1/2 (miroku mk38) will try the obturator option thanks Quote Link to comment Share on other sites More sharing options...
