There lube grooves are real small for this boolit. That not a lot of lube . I get more leading with this boolit then the rest of my molds for 45 acp/auto rim are do i need to have harded lead:-?

Make sure you are sizing to 0.001" over barrel groove diameter, and use a great lube like LPT Blue or White Label Red Carnauba as stuff like 50/50 or plain Liquid Alox isn't going to work.

Hi, I've used this bullet quite a bit and never had any leading issues. As already pointed out it should be sized .001 over groove diameter. The lube grooves are adequate as the bullet does not have to travel far in a revolver or auto. You ought to change lubes. I used the NRA 50/50 formula and even concoctions with beeswax and vaseline and things worked fine. There are lots of commercial lubes and homebrew lubes around to choose from so don't confine yourself to Lee Liquid Alox or struggle with a lube that doesn't work. There should not be any leading at all with this bullet. Another factor that can cause leading is too much of a fast powder. You didn't mention what powder you are using, but 800-900 fps is usually what 45's move at....and even slower for serious target work. 45 ACP or Rim doesn't really travel that fast anyway so it doesn't really need hard bullets unless one wants to make sure there is no denting of noses from the feed ramp(in autos) so it may not be worth it to quench harden the bullets or use lino. I've used WW without a prob. 201 is a good bullet design with the right shape for feeding and cutting clean holes in the target, so hang in there and try changing a few of the variables. Good shooting. LLS

I get more leading out of s/w625 then i do my 1911. I have used rcbs rifle and handgun lube that what i can fine here. As far powder 231, wst bulleye a little and unique. size 452. i also like the autocomp for Winchester it work real well in my 625 so far. i think its is a slower powder thank for the help COAT:-D

I used to shoot that bullet. What alloy are you using? It could be the alloy is too hard for 45acp pressures.

Lyman #2 i think i have somebody mix it for my and maybe not that hard.I have read it needs to be a little hard for my s/w 625.

[Lloyd Smale]

If the bullet is fitted to your gun properly it will do better the harder it is. Especially in your 625

[softpoint]

One of the most accurate bullets I've used in my 625's and 1911's. May just need to tweak the alloy, check the size, maybe go to a slower powder.

A boolit is never too hard if fit to the gun.
Soft or under size boolits and poor lube will cause more leading then anything. A poor lube, even with the right boolit will lead the bore.
Pay attention, if you have no problems with jacketed, why not duplicate jacketed hardness?????? [smilie=1:

I agree totaly! If even a lineotype bullet or a water dropped bullet leads its not the alloy its either the lube, the bullet size, or the gun thats the fault. A boolit is never too hard if fit to the gun.
Soft or under size boolits and poor lube will cause more leading then anything. A poor lube, even with the right boolit will lead the bore.
