I'm new to reloading and have a quick question.  I loaded some 338 win mag rounds and was unable to chamber most of the rounds in my gun.  I checked the over all length and that was correct, so I think that I crimped them too much and deformed the bullets a little.  I was able to force the rounds into the chamber with some difficulty, and they got a little easier after a few times.  Still a little tight though.  Are these safe to shoot or should I just scrap them.  thank you.

dont force stuff anymore, did make absolutely sure that you sized the cases completly 100% all the way? i had this same issue with my 22-250 last week and i thought the cases  needed a trim, but it turned out that when i re sized the cases last year about this time that i didnt have my die set deep enough and they wouldnt chamber up either so i resized them again and they worked like they should.
 why are you crimping??? may i ask??  i wouldnt shoot anything, pictures of the cases would be really nice to see as well

Promise not to force things anymore.  I'm sure the resizing die was set correct, cause I actually loaded 40 rounds and the first 20 I crimped them the way that the book I read suggested.  It felt like I was having to pull a little hard on the press.  After 20 I decided to loosen up on the crimp and those are the ones that loaded fine in the rifle.  The only reason that I was crimping them is because the book said to crimp magnum calibers and all revolvers.  I had a feeling that I should have stopped sooner.  I would rather scrap them all instead of hurt myself.  I wish there was a class on reloading, cause the books don't answer all my questions.  Should I not be crimping these things?  thank you

i dont crimp anything, and since i dont reload for pistol i really have no need to, you need to get yourself a bullet puller if you dont have one already, any questions you have do not be affraid to ask me, i can probably get you an answer either from my own experiences or one of my other reloading partners in here
so what do you have questions about?

  Crimping the bullets into the case mouths of hard-recoiling cartridges is done to prevent the bullet from being pushed back into the case in rifles with box magazines. EXAMPLE:  You go elephant hunting with your trusty .577 RONK magnum. It is a bolt gun with a 4-round box magazine. Upon entering the bush, you stuff 4 cartridges into the magazine and one into the chamber.

Well, the recoil from the first four elephants you shoot slams the front of the magazine well backward into the bullet nose of each of the cartridges in the magazine. The first three cartridges manage to hold up, but the fourth shot finally drives the bullet completely into the case of the fifth cartridge in your gun. (Which is actually the first one you placed into the magazine this morning.)  No matter. You're rifle now jams up hopelessly and elephant #5 drives you into the ground up to your armpits.
 That is why crimping magnum-class rifle cartridges is often recommended.
 Your Milage May Vary....

class of real world
if you want to crimp use a lee in the last step, these squeeze the brass around the mouth --I use them on .223 and .308 for auto loaders, in some loads.

I can agree some bif bore rounds do need crimping but under normal shooting no it dosen't if it's not shooting right then something is wrong somewhere. As for chambering sound like the die might not size the brass like it should was this brass fired?

It's hard to say for certain without examining them, but I would hazard a guess that your crimping operation pushed the whole neck toward the case head, buckling the shoulder slightly outward, thereby increasing it's diameter just enough to cause the chambering issues you ran into. If that is the case, you may be able to see a slight shiny ring at the shoulder/body junction after extracting a live round, where it was burnished by the chamber wall upon chambering. If you feel that your shooting circumstances require a crimp, Lee factory crimp dies are the only way to fly. In many cases, a light crimp can improve accuracy, the theory being that start pressure can be made much more uniform within a batch of handloads by lightly crimping them.

Well I think you are right Ronk.  I do see a shiny ring around the  shoulder/body junction.  I will not do that again.  Since they will chamber now with just a slight push on the bolt, would it hurt to shoot them anyway?  Thanks

 Over the Internet, it would be rather foolish and irresponsible of me to tell you to just go ahead and fire them.....Whistling

like i said some pictures of them would be helpful, but i would probably use a bullet puller or pliers and just put the powder back in the can and start over.

Your right Ronk.  That was a stupid question.  I'm gonna take pyro's advice and remove the bullets and start over.  I need the practice anyways.  Thanks

it just sucks because you have to waste the cases and the primers and the bullets plus the time you spent to do it, that is one bad thing about screwing up while reloading, it can take twice as long to fix stuff as it does to do it right from the start but you wont ever do everything perfect, you will get ahead of yourself and screw up again i know i do from time to time so yeah it will make for more practice.

 I have been there a few times too. I hate to dismantle ammo that is probably just fine to fire, but it's best to play it safe and start over. BTW, I used an inertia bullet puller until I couldn't stand it anymore. (The hollow hammer gizmo.)  Now when I need to pull bullets, I just run them up into a press without a die in it, with a large washer on top, grab the bullet with a pliers, and lever it back down.  Faster, easier, cheaper. Usually sort of wrecks the bullet, though.

i hate pounding on small diameter stuff like those 22-250's they take forever, not enough powder to make it work right, start doing some .338's its pretty easy 2-3 smacks on the concrete and your done, until i got a bullet puller i used my pliers too but didnt use the press to help

while it may not seem worth it at the time, RCBS tapered collet bullet puller is well worth the money, especially if the caliber is your favorite, and will be around for a while. the round is run into the collet, collet then tightened ram handle eased down and there is the bullet, reusable.

Yeah Pyro, the bigger heavy bullet stuff works a lot better in an inertia puller than the small calibers, that's for sure. I'll have try Dale's suggestion for the collet pullers, at least for the more common calibers. They are a little pricey, but with the cost of bullets these days it wouldn't take too many saved bullets to earn it's keep. Forster also makes a really neat device that looks like it might work pretty well, but marks the bullet at least a little.  Anybody use one of those?

before i bought another bullet puller, (had one then i moved and didnt buy another one till recently) i used rags and a pair of pliers, no marks on the bullet but man it took forever, i shoot cheapo sierra bullets so if i have to throw a few away its not a big deal, if they were swift a frames or barnes tsx then it would be another story, one nice thing about the nosler accubond and ballistic tip, the plastic tips dont take to much of a beating

I use an inertia bullet puller with a wad of tissue in the end to protect the bullet tips from damage when they drop. Mine uses the one expandable collett and seems to pull any cartridge with a couple hard taps on my vice. Bullets ain't cheap and expendable anymore.....

A soft foam ear plug in the bottom of the inertia bullet puller also works.

You might think about getting a set of Lee Collet dies.  I use those for my .338, and they work extremely well.  Essentially, they neck-size the case.  This reduces stress on the case,  which has already been fire-formed to fit the chamber of the rifle from which it was fired.
