I would recommend weighing your shot charge and removing only enough shot to get a good crimp or changing wad to a Gualandi 1618 wad for your 16 gauge to accommodate the increased volume and not rely on volume measurement alone. Squib loads are usually attributed to reduced powder drops not lighter shot charge weight.

Maybe you already know but Damascus barrel guns can be shot with nitro loads. I have three 10ga Damascus guns and shoot modern 3 1/2" shells cut to 2 7/8, or whatever you want. The brass shells and BP does sound really nice if that's what you like. I'm a old BP shooter and keep a couple of boxes loaded up for fun.

I agree with you Paul, I am usually more concerned with recoil and cracking the wrist of the stock of the 110 to 120 year old doubles!
Unfortunately, I have had that experience

Thanks to all for the input. Flintfan, thanks for confirming what I had read about tungsten-based shot. Paul, I am familiar with nitro for black loads but would like to use BP.

Should buffer be used in BP bismuth loads?

Only if you want to really tighten up the patterns. But, know that the addition of buffer will raise your chamber pressures.

Copper shot is softer than TMX and TM, steel and hevi shot, your only other options are niceshot or bismuth,



Nice shot is about £80 / KG here. - Each cartridge has £2.40 worth of shot in it assuming 30 gram loads.

Busmith is running at £61 / KG - each cartridge has £1.80 worth of shot.

ITX is harder than copper and thats £50/ KG - which mean a 30 gram cartridge is £ 1.51 worth of shot.

Copper is £18.40 / KG - making each cartridge cost 0.55 pence next to steel copper is the most cost effective - Im going to experiment with a card shot cup - im not convinced there will be any scoring to barrels - iron is much harder than copper surely?

brinell hardness scale below shows different hardness's of shot materials - if anyone knows what the hardness of your average Damascus barrel is that would be helpful but its very clear why hevishot - steel and tungsten iron are unsuitable.

Edit - Apparently cast iron has a brinell of about ~ 220..

Copper per cartridge is nearly 1/3rd the cost of bismuth - i am sure i could cope with annealing enough for 10 - 15 cartridges if its saving me over £1 per cartridge to do so.



The real answer is to get a gun that shoots steel.

Steel shot can be at at £2.50 /kg - Each cartridge has 0.07 pence of shot in it.

The Solo 1250 is a couple of years old, when it is used up I will be looking for another recipe. I have not seen it, nor SR7625, nor PB in quite a while. I have buddies who go to a lot of gun shows but do not reload looking for me. Sometimes I get lucky


I did find two 1 pound containers of SR7625 at a small gun show this afternoon in Columbia.
