neck tension observation
this is just an observation from some reloading work i was doing today. using a kinetic hammer type bullet puller i observed while pulling some 22 Nosler
re-loaded ammo down. i noted how many whacks it took to dislodge the bullet. some took as little as 2 whacks and others as many as 12. question, what effect do you think neck tension in these cases might have on standard deviation and extreme spread as well as accuracy. note: there were several that required 4 and just about as many at 10-12 whacks. sorry for heading misspellings

Generally speaking this is a function of brass hardening. It can have quite an effect on accuracy. The necks "spring back," either after coming out of a bushing type die or back over an expander ball. I have seen it with Lee Collet Dies as well, but normally not to the same degree. When brass is uniformly annealed it will take care of that spring back.

I had 200 40gr V'max to pull once.
That was a real PITA! Same way, with a hammer puller. I've been putting the next batch off. Don't know how many there are, 2/3's of a 50 cal can though. Might be good for me the majority of them were stolen. I had a two gallon bucket full, he got most of them, and 3 gallons of 55gr too. I had 5 gallon bucket of those loaded with a safe charge of 25gr 4895. Lotta bucks worth even back then. Just think what they'd be worth at todays prices. At the time I was shooting a few hundred every week at p/dogs. About that time I picked up an over flowing 30 gal trash can of brass after a 4 day LEO shoot. There was three of those cans full, I got one and helped another guy load a 2nd. we left the third for someone else. I traded most of them off for other things I needed an kept I think 8 or 10 gallons for my own use. Screw the count, I judge such things by the gallon! Even when casting pistol bullets. I got mixed up loading AA2200, max is 23 gr, I loaded 25! Way too hot for my Sako. Guy that stole them said he and brother both had AR's. No feed back on how they shot. I'd bet those guns would take a hammering. I've wondered if the semi auto could handle them easier or not. Anyone have such feed back?

A few years back, I needed some S&B 6.8mm brass. I bought 5 boxes of factory (100 rnds) from Academy with free shipping. Price was cheaper than buying just the components. I pulled the bullets, dumped the unknown powder & sold the bullets. I used the primers to load some .223 plinking ammo. I have a RCBS collet type bullet puller & an inertial hammer. My experience is that the collet marks the bullet a bit. The hammer always yields an unmolested bullet so that's the route I took. NO FUN - that ammo had crimps to make things extra hard (LOL)! On a better note, my arm & elbow made a full recovery. Typical AR15 bolts can develop tiny fractures on the bolt lugs with the extensive use of HOT ammo. The good thing about AR's is that, if you're lucky & notice the problem before it blows up in your face, you just buy another bolt & drop it in - no tools required. BTW: If you know the guys that stole the ammo, why didn't you call them out on it? Last edited by pertnear; 06-10-2022 at 02:15 PM. Reason: bad grammer fixed |

They are no longer made, but Forster possum type bullet pullers make fast work of disassembling loaded rounds. To the best of my knowledge there isn't any ammo they won't snatch apart in a single stroke and the next round pushes the bullet from the last round out. I broke down barrels of military ammo using a couple of them in the 1990s and sold the bullets to a guy who said he could not see any difference in accuracy using them or using brand new bullets.

ray h to the rescue!
Funny this subject came up on bullet pullers recently, but I personally hate using the Kinetic hammer bullet puller...but it's been the only way I've found until yesterday that didn't mar bullets. Last April when Ray was out here on his annual GS shoot I had a problem with my 17 AH that was blowing primers (haven't figured out why yet). Same load I been shooting for a while. Anyhow I put the rifle up and went to a different one. I've been procrastinating about pulling (450) rds of 17 AH for months.
Ray sent me a oilube powdered thrust washer to put between the top of my RCBS bullet puller handle and the top of the die. I have never liked that puller because it mars the bullets most of the time. The washer solved the problem...and it is "fast" compared to the hammer puller. Yesterday I pulled (200) 17 AH loads apart in about an hour. At one point I timed (5) a minute! Someimes I think I know a lot about small calibers...then there's Ray...Lol! The guy knows his stuff! That's what this forum used to be about...helping one another. Wished it was still like that all the time! 410gauge Last edited by 410gauge; 06-10-2022 at 05:42 PM. |

So true, seems like more now want to slam the other guy for his opinion or thought. |

The Grip-N-Pull bullet puller works well and is fast but it can sometimes leave a bit of a ring on some bullets. I polished the holes in mine with 0000 super fine steel wool and that helped nearly eliminate that little ring.

I have had a kinetic bullet puller for years, and they work pretty well for heavy pistol rounds. More than ten years ago, I got the Hornady collet style bullet puller, and never used the kinetic style again. Haven't seen any issue with marking the bullets or other problem. And it is sure easier on your arm and hand than using the hammer style.
