Stocking up

[Pistolero]

IME, W748 is superb in .45-70 with 405 gr cast or jbullets. Accurate, low pressure -
makes trapdoor level loads - but makes 1750 fps at that low pressure.

Seems like Dacron means you have the wrong powder. But, I haven't really ever
used it. Kinds like turbos on cars - means the motor is too small and you are
trying to compensate.

Didn't need the 2 lbs of tight group that I picked up yesterday,
but the price was right, It doesn't spoil and on a cold day when
the wind is howling and snow is blowing, it will load a lot of 9MM.

be careful with titegroup in the 9m's.
I have shot a fair bit of it in them but if you get one bullet set back you'll know it right off.
I think titegroup is best suited for the big volume cases.
but it's hard to beat the price per lb.

 

[KHornet]

Will take your word for it Fiver, and will watch closely for set back.
Appreciate the advice. Would you mind sharing your load?

start at 3 and move up slowly.
I have been running red-dot and bulls-eye at 3.2 and it's a nice load that just drops the cases about 2' to my right in a nice little pile.
it also keeps the bullets on the paper in the same scattered shaky wobbly pattern my front sight has.
when I settle down and hold everything straight the holes do the same thing.

I blew up a 1911 with TG, bullets that were too soft, and a too-small resizing die that I'd been using to prevent boolit squish. Very dumb move on my part for not verifying case tension by at least pushing the cartridges bullet-first against the edge of my bench. Post mortem showed bullets of unfired rounds that had been in the magazine were knocked back in the cases under recoil and the TG really doesn't like small spaces and heavy bullets. Blew a hole in the case head, ruined the stocks, trigger stirrup, and magazine. Gunsmith checked it and no harm done other than that, gun is still in service.

Once again, God Bless John Browning.

Thanks Fiver, what bullet?

Ian, how soft! I seldom cast anything under 14 BH?

8-9 bhn as I recall, not sure now, it's been a while. The main issue was inadequate case tension. I was having leading due to tight brass and soft bullets (Lee carbide sizing die) so I switched to a different sizing die, .45 Colt as I recall. It didn't make enough tension to hold the bullet under recoil in the magazine nor did the expander make a step and wasp waist in the case which gives the bullet base some sort of a back-stop to seat against. After the first shot, the bullets turtled in the brass, case volume decreased, and a mild load became dangerously overpressure. This could have happened with any fast powder I suppose, but with Titegroup, there seems to be a sudden point when increasing loading density where pressure takes off and climbs exponentially.

 

[fiver]

your 14 would be fine.
I'm probably in the 12 range.

I have what I call a big batch of alloy.
it's all of my ww alloy and about 1/3 of that is soft alloy and I mixed it all together into one big batch.
I use it for everything.
water dropping for some, air cooling for others, but for my 9's I add 1 part lino-type to 8 parts of that alloy.
which basically brings it back to old school ww's with a little more tin.
oh I also size to 358.
I think the extra hardness helps fight the squish from the small sized brass, but I also use the powder funnel from my 38 special to make sure the inside of the case gets opened just a bit more than the 9m opens the case.

how I check for set-back is to run the round through from the magazine 4 times and measure the set-back on the oal.
at 4 I should start to see some movement, if I see it before that I need more case tension.

 

[KHornet]

Sounded like a good process fiver. I tried it with some recently loaded
9MM's, and found no set back, but consider it a good test. I size to
.357 with Lee multi groove 124 Tri, and think I have it down pretty well.
