pulled bullet gouges...affects accuracy or reloading?

[ExtremeX]

Sure a gouge in the jacket may not but I have seen some machine pulled bullets that were deformed. And that must throw of the rotational balance affecting accuracy.

Air pulled, collet pulled, machine pulled.

Those air pulled bullets look good as new.

Don't have the FPS data off hand but one ragged whole at 300yards 1inch groups at 600.. Not bad for pulled projectiles IMO..

You are either a extremely good shooter, very lucky, or a very good story teller...

1/6 moa? Wow.

[cpatbay]

Does the M118 bullet attract a magnet?

No, they don't. They are not steel core.

1/6 moa? Wow.

Must also be a windless day as well !!

Oh boy, oh boy, I get to comment! Being cheap, and extremely lackadaisical, I used a bunch of collet pulled .224" Varmint Grenades in some initial loads for a new barrel. They had score rings around them, but so what? Well, for one thing the cores aren't soft and pliable like lead, they're more like a copper chalk stick. Hoped they didn't crack from being pulled. Shot one of the smallest groups of all time, at least my lifetime, which drove me to order a Wendy's #4 with extra side of fries on the way home from the range. What a celebration!

I am a story teller.. You happy? Or you calling me out. Take your pic..
Just to clarify some things for you, very simple.. The 6BR you referred to has ancestry leading back to what European country, what 6MM cartridge and why is it still considered a hunting round in Eastern Europe. How did it evolve as a competition bullet and how many variations came from it. My elders use to shoot this particular round for medium game and still do.. So what 6MM cartridge sparked this American Bench Rest Revolution. Mind you the 260 Remington and the 6.5X284 existed in the US..Ole boy Kennedy was assassinated with a 6.5X284.. So. 6MM, 6.5MM. 6.5Xwhatever.. How did this come about, I still have rifles that shot these before any of us were born..

CLEVER

Here is the world record for 600 yards BR competition. Just saying...

and they are definitely not using factory rifles!

PS. Unless your name is Wolf or Terry... then my apologies!

To paraphrase Winnie the Pooh, I'm a bear of little brain. So can someone tell me what's the big booboo about using acetone to wipe down bullets?

there's no issues with it. the guy was probably thinking why i care whether or not there is sealant on the bullets.

it's like telling people, why do you clean your house, why do you wash your clothes, and i guess as it pertains to firearms and this forum...why do you clean your gun, or why do you care what the muzzle brake looks like.

Some people take pride in the work they do, take pride in the cleanliness of their belongings, etc. That guy apparently doesn't.

If it makes you feel any better, I have used acetone on my pulled bullets. Mainly the 147gr and 152gr FMJ's, since they have a lot more of the tar than the pulled 175gr M118LR bullets.

I like nice shiny bullets just like you do. I also tumble my brass until they're nice and shiny. I have plenty of people tell me how that's useless, but that's how I like them, so that's how I process them.

In my earlier post, I mentioned gouges on the boat tail of the bullets. What I mean by them are vertical gouges along the boat tail. For some reason that I don't know why, it affects accuracy on some of the bullets. As for the circular crimp ring on the bullet, I don't think it matters. Like I mentioned in my previous post, I'm getting 1/2 to 3/4 MOA at 100 yards. The rifle I'm shooting it in is a Remington 700 PSS with Leupold M3 scope. It is my departmental issue sniper rifle, so technically, it doesn't belong to me.

You should be fine. I shot pulled 250gr SMK's 338 LM out of my TRG with very good results.
This was my data
Pulled 250gr SMK 338 LM
Lands at 3.755
Seated Mag Length/OAL 3.740 which is .015 jump
Lapua Case Trimmed to 2.714
Federal 215 Primer
Powder 92.4gr of N165
Don't have the FPS data off hand but one ragged whole at 300yards 1inch groups at 600.. Not bad for pulled projectiles IMO..

One ragged whole...and 1" groups at 600 yards...that would be almost good enough to set a world record ,.....if it was one ragged hole instead!! Thats 0.166 moa and taking account for wind I would say...that's crazy.

And....you would better the current world record set in completion by 50%! Now that's simply.....amazing??!?!?


To answer the original question, any changes to the concentricity of the bullet about its axis is surely going to make a bullet less accurate, and a crease in the jacket will affect the concentricty. At high speed rotation any variation or non symmetry about the axis will eventually pull a bullet off course.

Okay, I'll bite:

If your tongue might detect the presence of microscopic acetone particles in a coffee cup recently cleaned with it, what kind of reaction do you think the same amount of acetone might have with the gunpowder in a air tight cartridge case?

I'd be Reloading 7.62x51mm for the next 30 years and I don't think I'd ever think of cruising the painting isle at Home Dee-Pot in search of improving shooting accuracy. Maybe I could learn something here?


Don't take my word for it. Ask the person who issued you the rifle. If I issued a Remington to someone and they used home Reloads with pulled bullets and acetone, no less, and produced half-inch groups I know I'd want to know about it.

thats why you wipe them down with a wet rag of water....

Wait... wait... you are not really claiming that acetone is left on anything that you clean with it right? Because that's "non-science" crazy talk. Acetone leaves no residue when it evaporates. Non Reagent grade acetone may have impurities in it that are left behind but those will be in extremely small trace quantities if they do not also evaporate. Pro tip: most of the impurities found in consumer grade acetone would also evaporate with the acetone. Pro tip #2: the impurity with the greatest quantity found in consumer grade acetone is in most measured cases <.5% and is water, the next are isopropyl alcohol and methanol, both of which are fine cleaners in themselves.
