Kent 3.5 inch 2 oz tungsten shells


Recommended Posts

Bismuth is around 12 quid a kilo in 99% pure ingots ok you have to mix in 3% to ^% tin dependent on what you want, and you have to mold it or drop it into shot ...yet more work, but ITM is just too silly to realisticaly conssider unless you are a lottery winner or an oil barron.

Bismuth is not quite the same Specific gravity as ITM but its very close, and Copper is pretty close to bismuth and cheaper to buy than ITX10 or Bismuth in shot form.

If you dont want any work input yourself COPPER IS A VIABLE OPTION and you can load it traditionaly in anything. .

sure i saw somewhere that a bloke was loading BB in copper as i thought at the time i would"t mind having a few kg in that size

I got some 4.2 mm from germany, but its not available from them over there anymore, rotweil loaded 4.2 in the sweets shot ammo originaly but discontinued it, Siarm only ever listed 3.5mm which is usa 3s which is bigger than english 2s an english 1 if there was such a thing. English 2s are 3.42 and single B american 2s are 3.8mm to put things into true perspective and siarms 3.5mm are a true 3.5mm size ive not meassured one smaller than 3.5mm from them.

It looks a bit more interesting if you look at the sizes not just shot numbers, and if you start to look at the spacific gravity of ITM Bismuth by the time you have added 3% the minimum tin to keep up the mass, or worse still looked at factory bismuth shot with 6% tin and big shot even more, the pure copper 3.5mm shot looks not quite as lame as it did at first first glance, and couple this to the fact you can send it like steel speeds if you want it weighs heavier is lower volume thus lower pressure even more you can try and harness or keep it as an even greater added safetey margin, humble copper is not all bad news at all.

Its just over 45 quid for 2.5 kilo, if you just buy a tub the shiping takes it up a good bit, i think i ordered a fair bit of stuff off them it made it pretty decent then on price. Cant remember who it was now, but someone posed up a bill for some and it looked way more expensive than i remember paying for mine.

I did get 7.5 kilo in one order though if i remember and other stuff, Cant remember now but its free shiping over so much money something like that. Go on the site read the info im on this phone its awkward for me to look on this thing on siarm, better on a i mac or even a lap top better than this have a look.

Had a ring around and found some 3s at £15 quid a box and some 1s at 24 quid a box at 2 different shops. Another place wanted £49.50 for a box.

 

Off to get the cheaper ones

:lol: :lol: Thats pretty radical price variation right there, well done on flushing out some at a low price buy it wile its there i am guessing. :yes:

Done and in the safe now! Rather ironically three inch no3s were more expensive....

There is'nt much data on loading copper, could you take a bismuth load and substitute copper, or could you take an ITX10 load and substitute copper instead?

 

I know sub'ing is supposed to be a no no, but i was just wondering would it be possible/sensible? :hmm::hmm:

Substituting shot of similar density shouldn't be a problem.

As I have never been an advocate of switching components, I would say. No.

But I tested loads last year and switched lot lead and steel. Switching from 24g lead to 35 lead only raised 120 bar. So near identical charges I would.

So I agree with Motty.

Just short of 53 euros for 2.5kg i want some hulls an a ew other bits to so might be ok on shipping

As moty and cookie say its safe enough and the logical place to start subing is with the ITX10 data, or indeed Bismuth which is a similar density, With copper being pretty tough and with it being in no way fragile and ever so slightly lighter i tend to load it slightly more towards steel speeds and the lowervolume of copper helps here i found on the pressure tests.

Ill stick my neck out now and generalise a little here.... Imagine your comfortable loading say 28 gram of steel at 1600fps there is no reason why you could not send a load of say 30 gram of copper at the same speed and even in a 30 gram payload with similar pressures, this helps bump up the pellet count and the denser shot at same speed is just the icing on the cake.

This in no way is advocating any direct substitution implied or otherwise, its just a cassual observation and remember you need to creep up on any load not just leap in as is for a first test.

Pressure test guns are a handy addition.

But remember all loads started some where most of them started in normal guns, before being tested, testing is the conclusion not the conception, start low work up steady is the key.
