S+K; ammo seems a little greasy...........



Log in to see fewer ads
Recently purchased a few boxes of S+K "flat-nose basic" and "Standard Plus". The bullets in both types look really perfect. I picked a few out of the box to get a closer look and there seems to be a light coating of some kind of grease or oil on the bullets. Is this a feature added to enhance accuracy? Also I noticed that they have a new ammo for 2019 they call "long range", rated at slightly over 1100 fps, any info on this stuff?..............................

I wish I knew what the grease is on the SK ammo. It's worked very well for me. I had a rifle that would throw the first couple bullets way left with most ammo but not Wolf Std ( SK ) I had. Also, my CZ doesn't like CCI STD but the first group with CCI after shooting SK will be a good group, fliers after that.

That "grease" is bullet lube. Without it the bare lead bullets would lead the barrel. And yes it is there for accuracy. Steve Bolter wrote in his book that you need about one fired round per inch of clean barrel to properly lube the barrel for consistent precision. That's true to a certain extent but some find their barrel require less rounds. Now you can do as some do and wipe it off but be prepared to have your precision go down hill quickly as the barrel leads and then you can spend a lot of time trying to remove the lead.

BTW all .22 lead bullets have some lube on them. Most subsonic ammo has "grease" while HV ammo usually has wax. Is is commonly assumed that the main ingredient is bees wax but there are a lot of proprietary ingredients as well.

Thanks so much for the inputs. I kind of figured it was a proprietary lube on the bullets. I fired a box of old S+K from 12-14 years ago recently and the coating on them was like a wax that was starting to form little white bumps on it; still shot great though. Looking forward to giving this stuff a try......................

Ray.

As other members have alluded to; 22 ammo is almost always covered in a lubricant. The proper wording is lubed.

On some ammo its very sticky/tacky like honey/wax, on others its like a light grease and on other ammo its similar to a fine coat of oil. Each manufacturer has its own mixture.

SK Ammo is on the oily side while Eley/RWS is on the tacky/sticky side,IMHO.

Very good post and spot on.

I just got a new rifle so, of course, I had to try some of the whole stash of ammo this old man has accumulated over the last 10 years. One that I tested was just purchased from Grafs.com, two "cans" of SK Magazine, the bulk form of the boxed STD+. Well, while this was the first time I bought any Magazine, others here led me to believe it would be well lubed. Yes! I just dumped the whole can on a cotton washcloth and rolled them around a bit. I wasn't trying to remove the lube, just what I thought might be excess compared to what I experience with boxed STD+. At the range the bulk ammo was nearly perfect and at least as good as anything else I tried including Lapua Center-X, SK Match, Pistol Match Spec. (old and new editions), Flatnose Basic and Flatnose Match, CCI-SV, and RWS Match Rifle. OK, maybe I got lucky, but whatever "grease" SK uses I, and my rifles, really like it.

SK is my favourite round to use, or Lapua when I can spend up a little. I put their accuracy down to consistent manufacture including their lube.

The lube is such that I don’t mind only bore cleaning my mainly used rifle once a year or every 1500-2000 rounds.

In cold weather, the SK lube hardens up a little and makes the round much nicer to handle.

I’ve got myself a P94s Varmint awaiting pickup at my LGS, here’s hoping it also likes SK!

Quite some time ago, I bought several bricks (IIRC, about 7 bricks) of Eley Match Xtra from Champion's Choice that was - shall we say - outdated? The lot# was ALC064, and the reason I bought so much of it was that it was priced at $39/500, and because it shot pretty well out of a H&R M12 I'd bought from the CMP. However, over the past few years, the waxy lube on this ammo has started to dry out, turning grey, with some having a few spots of white that likes to flake off when the bullet is seated in a repeater. Such flaking quickly fouls the action of a repeater, and of course, when the bullet lube is left in the action, it tends to lead the bbl a bit. I'm not the first one who has posted about dried-out bullet lube here - have read a few similar posts before. This ammo was stored in my basement, where temps tend to stay fairly constant depending on the season; the upstairs has central heating & a/c, but there are no outlets in the basement. I should've shot this ammo up long ago, while the lube was still good, but it was set aside & kind of forgotten while I chased SK & Lapua lots for a couple of Anschutz prone rifles & later, custom barreled repeaters.

The oldest SK/Lapua I've got is some that was bought right after I'd purchased a poor lot of the old SK-made Wolf Match Extra, so that stuff is at least 10-11yrs old. The bullet lube on this ammo is definitely starting to dry out a bit compared to fresh SK, but it's not flaking off, nor does it lead bores.

Hey armtx & Pete- this an excerpt from a post I made just yesterday-

SK Magazine-

The cans come with LOTS of lube- which can be a PITA, but you can use it to your advantage by pouring out half of the Magazine and putting it in an empty can, then mixing in a couple hundred rounds of CCISV into each can. Roll them around gently, to apply the SK lube to the CCI ammo, and you will find that the CCISV shoots much better with the SK lube applied.

Hope this helps-

DrGunner

Wow!, you guys are really SHARP..... Thats great about the SK lube on the CCISV ammo. I have a few ideas about some synthetic lubes for my CCI and select Aguila ammo. I guess its just a matter of trial and error?..........................

I think you have posted that before and that is why I started doing it.

It has given me exceptional results with CCI SV and the 452 Super Match stacks both of them way above their price point.

I still shake my head how different lubes affect the ammo.

When I see Magazine at a good price, I always pick up a couple of cans.
