anyone shooting the Lee 356-120-tc

I have been shooting this bullet for some time with a OAL of 1.11 but that puts the lube groove just below the case mouth. Do you seat them deeper? Just wondering it looks like there is allot of slug hanging out of the case. TIA

I load my Lee 120 TC in 9mm to 1.075" with 8 grains of Blue Dot. Shoots very well.

I load mine at 1.065 using Unique. This bullet is very accurate in my pistols and a 9mm AR15. I adjusted the length in and out to find the an OAL that would work in a very finicky P08. If you have a load that works at your OAL, don't worry about it.

Thanks for the input. I am interested in those that are using unique and how much. I have been using 5.4 grains at this length. I wonder if I should back off a bit if I seat it deeper?

[Gunslinger]

If 5.4gr is maximum with the COL that you use now, then yes you should back off it if you seat it deeper. A friend and I both use that bullet. He uses 4.2gr Unique and I load it with 5gr Vihtavouri N340. I'll measure our COL later today and give you an update.

I find our loads to very accurate...

We seat them to 1.080. The listet COL in Vv load data is 1.130.

I loaded some at 1.075 and reduced the charge to 4.9 grains. I shot 100 and they all fed flawlessly but it shoots low. I dont remember if I should speed it up or slo it down to make it shoot higher. I also modified the slide stop on my CZ75 so that the longer 147 grain boolits dont snag on it. I didnt shoot any but I will next time. TIA

What do you shoot them out of? Don't have no adjustable sights?

I shoot them out of a CZ75B with fixed sights. Thanks! ;)

To raise POI
Slow down
More barrel time allows recoil to raise the muzzle before the bullet exits

Thanks johnch. I will do just that.
