Zero 185 SWC Lubrication?

Post by Dcforman on 11/22/2017, 7:05 am

Hey Guys!

Newer shooter, first time poster .

Did some searching, couldn't find an answer. This may be a bit of a newbie question, as I'm getting ready to start reloading... Do Zero swaged bullets come lubed? Do all swaged bullets come lubed?

Is it correct to operate under the assumption that as long as I keep velocities down, and make sure the bullet is 0.001-0.002" wider than my bore, that I shouldn't have significant leading issues? And if my bore is the same width, I should use something like 45/45/10 to prevent Leading? 

Shooting out of a series 70 gold cup, circa early 70's.

Thanks in advance! Happy to be here.

Dave

Typically the hard cast bullets we see today do not lead at our velocities but you will see it sometimes with the swaged billets.. I make it a habit to tumble lube my swaged bullets in 45-45-10.

swaged bullets are usually tumble lubed with some sort of liquid lube that dries on them.

All the 45 caliber swaged bullets I've ever bought had a Lube Groove that was full of lube. I didn't even know they were offering a swaged bullet with tumble Lube. What brands are tumble lubed?

I had some Hornady 38 bullets that appeared to be tumble lubed. The bearing surface was knurled, no lube groove

Ralph,
I knew .38 came lubed like that. I've just never seen 45 bullets sold tumble lubed. I'm aware of the Lee tumble lube bullets.

All the original star bullets were tumble lubed with either a sticky black that use to be sold in plastic tubes then they came out with special match lube it was sort of a white grey lube, the copies of this bullet from zero,magnus and delta precision are all tumble lubed with some sort of tumble lube, and none have any true lube groves on the bullets only one band with hash marks to hold the lube.

You have to specifically order unlubed cast bullets. Otherwise, all lead bullets are lubed.
All the swaged bullets I know of are more than hard enough for 9x19, much less .45 and lubes work well.
The critical thing is that the bullet, after seating and crimping, is STILL at least 0.001" over GROOVE diameter. If it was just 0.002" over BORE diameter, gas cutting would be quite severe.
