It shows my Browning A5 was made in 1908.

2.2kg I assume you mean 2.2lb = 1kg but at £45 that is very cheap for 1 kg.

Most auto/pump extractors are stamped out of steel sheet and then hardened / tempered, Your way of hardening may work but I would only temper to a straw colour.

I do agree a bit of crimp would be better especially if used in a tube magazine , You do not want the bullet's being pushed back in to the cases and raising pressure's.

Use any data that uses an 158 grain lead head it does not have to specify a truncated cone a semi wadcutter will do or even round nose , It's all in the weight . You are well below maximum powder load's for n320 .8 of a grain below for a 158 swc. https://www.vihtavuori.com/reloading-data/handgun-reloading/?cartridge=41

If it's just a dished dent ,Spray the dent with water and after an hour use the wet cloth and hot iron method , If the dent has a sharp edge with the wood fibres broken you will not raise the dent fully as the steam water method will only work on distorted wood fibers and not broken one's , you will still be left with a blemish as the expanding wood fibres cannot do anything for a dent with a sharp edge as the wood fibres are broken.

Has anyone have a spare std 7 round 1911 45acp magazine that i can obtain for a project , Cheer's.

Yes and that is not Swiss It's a rebranded pyro powder they sell under the Krank name , It makes it only £10-00 a kg cheaper than the top grade Swiss BP.

I don't know where you are but if you are near the south coast ( Brighton), Try here http://www.gun-powder.co.uk/blackpowder.html They sell BP at £14-99 for 500g of coarse .

Working on the Vulcan B2 bombers that had been converted to tanker's.

Some moderators have a distortion in the bore orifice to swirl and distort/disrupt the gas flow which then helps moderate the sound level , The more you change/disrupt the gas flow the more it slows down . And it could just be a baffle strike.

Mine is an old browning A5 i bought at the old Weller and Dufty auction 20 years ago for £18 made in 1907 with super full choke and I replaced the woodwork 15 years ago with a plastic set as the woodwork has seen better days ( I still have it) , But I can shoot better with that than any other Gun I Have ever bought or tried including ,Beretta's and browning o/u's. The best one was when I cleared a 25 skeet with it and some of the other guy in the squad were so pee'd off they wanted to sell off the competiton grade o/u's when I told them it only cost me £ 18 to buy.

Yes degradable plastic in 6 months at 50-60c Where is that Death valley california.

The more up to date Alliant reloader guides do not list unique much any more for shotgun reloading as they have added so many more powders to the inventory American select , long shot etc
