PCP Pistols

Leshiy I think is 742 ,not so confident on the hatsan altho is going to be supressed. Fingers crossed

the only prob with lead head nails is the alloy not very consistant,and they allso often contain a % of antiminy,this metal is what makes lead harder and allso allows lead to be heat treated harder again,i personally wouldnt use lead head nails to produce airgun pellets or bullets unless alloyed in very small quantiys with pure lead  because antinimy will lead the barrel with unlubed airgun ammo,as airgun barrels are normally softer than firearms barrels they are easier to damage getting the lead out of the bore,you can use a bronze brush in firearms but doso to an airgun barrel will likely destroy the barrel.

airgun projectiles are normally made from pure lead,tin makes the alloy bit harder but in the right quantitys easier to cast in moulds,adding tin to alloys for swaging requires a lot more pressure to swage the bullet,big difference between bullets for firearms than bullets for airguns,bullets for firearms need to be lubed to prevent them leading up the barrel badly,and noramlly harder to better resist the significantly higher pressures and stresses put on bullets in firearms,purpose of lubing bullets for firearms is to help reduce the bullets leading up barrel,airgun bullets dont need lubing which is normally caused by the heat from gunpowder partually melting the base of the bullet,and leaving that residue in barrel,this can be reduced by copper gas checks on the base of harder lead bullets in firearms,it is possible to fire hard lead bullets in firearms up to 3000fps if bullets are wrapped with teflon tape with good accuracy,but normally lead bullets in firearms are best kept to no more than 2500fps max,unlubed soft lead as used in airguns wont significantly leave lead residue in barrel,but residue will build up slowly over time in airguns and needs to be removed to maintain accuracy,unlubed soft lead bullets can work extremely well in high powered pcp airguns at velocitys in the 1000/1500fps range,its possible to drive airgun bullets up to higher velocitys with good accuracy as well but generally to gain more energy in airguns bullet weights and calibers are increased and veloctys kept below 1200 fps,good source og info on shooting soft lead bullets in pcp airuns can be found on utube on US varmunt shooting posts and forums,these guys know what they are doing and talking about and are normally using calibers in the 25/30/35 range with decent weight projectiles at quite high velocitys in US made rifles some using nitrogen rather than hpa as nitrogen produces higher velocitys due to being thinner than air higher volumes can pass thru valve and is more free flowing than hpa,i believe swaging soft pure lead bullets produces the best bullets for airguns,as casting soft pure lead is more difficult to get good clean consistant weight bullets than swagind can,i can get swaged soft lead bullets to stay within 1/10 of a grain in weight,its not possible to cast pure lead bullets to that same consistancy.interesting topic.

Well thats way more than a few bullets, think their will be more reloading now with this ammo shortage.

I've just got some new roofing lead flashing offcuts and 50/50 lead solder bar to learn to cast by hand, will be making my own molds and just have to run a pellet through my .25 cal barrel to find out the groove and land diameter to size the cutting tool +0.001 over groove diameter. 40 bucks for 150 .30cal pellets id cast my own if NOE makes a run of their hunter pellet molds again its modeled off the jsb pellet.

Perfectly valid reasons Mike, think most people with a FAL are trying to do nothing that would put their license at risk. Funny that pcp airguns are limited to subsonic speeds so it takes an expensive rifle and high pressures to match equivalent firearms fpe, .25cal pcp can match a .22lr but at a much higher cost.

No pcp build threads on here might be a good idea, there are other forums to look at for that info..

Mike do you cast your own ammo for your builds, I noticed most websites and all nz sites are sold out of .30cal jsb pellets, could only buy .25cal jsb pellets.. here's some useful pics since you have the skills also to figure out the rest. USA made Noe pellet molds are good but usps aint shipping to nz anymore so we kiwis have to be resourceful.

I agree Paul - on a custom piece its nice to see how its assembled - screws and all. Shows the thought process and if they are nicely fitting it adds to the quality and craftsmanship!
