Fire forming 280 AI brass
better done with normal factory loaded ammunition or load lighter 280 rounds in new 280 brass..?
Obviously new 280 AI Norma brass is the way to go, just curious about fire forming.. |

resize to a crush fit in the 6.5 chamber prime and charge with 11 gr of unique, put a finger over the case mouth and tap once on the bench to settle the powder fill the case to the top of the case neck with corn meal, put a finger over the casemouth and tap once or so to settle the cornmeal to the bottom of the case neck now tear a 1.5" wide strip off a paper towel and twist it into a skinny worm, stick it into the case neck, wad it in till full then pinch it off, use a small punch to pack the plug in tight. keep muzzle pointed down, if you have a brake remove it, watch barrel heat (cause it'll get hot!) clean your barrel well when done, shoulders should come out just rounded on the edges, but will sharpen up nicely on the first full power firing. RR Might be easier to just shoot some core-loks, at least just for a little pointless range time...Could any accuracy, even remotely, be expected? |

So would you expect better results after the second full power firing? Essentially the first full power load would finish the job of the cornmeal and paper towel. Correct?

I've had fireform loads shoot 1/4" at 100...
Didn't Nosler just come out with .280 AI brass? |

Didn't Nosler just come out with .280 AI brass? Yeah, which is probably how I'd go, just a little curious about fire forming methods. |
I just load up some cheap bullets with a stout (not max, but not min either) load of a cheap powder and go shoot...

That's been my method also. |

RR-
Great pix..so you are actually chambering the empty case to crush fit or is that the done with a resizer die? You ever have a problem with blown shoulders shooting factory rounds instead of the cornmeal process? So essentially it would go through this order......(sans the blown shoulder) |
I've haven't lost any cases fireforming with Lapua brass, but I have lost a couple cases when fireforming with factory Remmy ammo...
|
Personally, Remington is about my last choice for brass, period. It just doesn't seem as ductile as most others. For going on the "cheap", I'll take Winchester brass..........
|
Me too, I just had a box of ammo and wanted to shoot it up one day...I don't think I even reloaded it after it was ackleyed out...haven't had any trouble with Winchester or Lapua, yet!

Seems a lot of jabber about Remmy and Winny, nothing about Federal......out of the question or what?

Damn, no love for federal. I think their shotshells are garbage anyway, except they still make purple 16 gauge shells.
Good info about fire forming, thanks...now just need get the gun built... |
Federals are the main thing I shoot in Trap and Sporting Clays...sometimes STS's or Rio's...

The talk about the "purple" 16 ga. reminded me of something that has ABSOLUTELY NOTHING to do with this topic, but here goes anyhow.... For those who could care....I've found a site that sells old specification shotshells..i.e....2 1/2" 16 ga., 2 1/2" 12 ga., etc. They are of new manufacture and come in a choice of shot size, weight, and powder charge. I bought a case of them for my old Parker 16 double which has 2 1/2" chambers. The cost is surprisingly reasonable, I feel. The web address....www.rstshells.com. The name of the shells is RST, and they are located in Pennsylvania. OK... I'm done.... |
Pa, caught ya on the other side....
The rest of ya need get on with B&P....Competition 2000 7/8's 7.5 at 1160 fps. Yep, sounds light and dainty but patterns like a dream. No kickey means you can shoot all day. They do have some heavy hitters if thats your liking. http://www.bandpusa.com/ The lead in their shells looks like ball bearings. Feds got nada with them in the shotgun department, except purple, which I'll get for nostalgia... B&P will have the fat brown santa put them on your door step for free.. |
Those B&P's look pretty good, just might have to order up a few cases...

Head over to shotgun world.com and check the B&P forum, sometimes they'll give you magic little discount codes. Plus, you can see what scoop is on the different offerings.... In the words of Relentless.......you'll thank me later (grin) (easy Mods, just a joke.........) |

Most of the rest is not so good. I load steel shot, which is a whole 'nother breed of cat. I load federals partly because that is what I have, and partly because that is what the best recipes are for. The hulls aren't very good, often the crimps blow off straight out of the box new, so I can maybe reload them twice. The aforemention gold medals have no problems. If you are loading lead, go with remmy sts, or nitro gold (they are the same) They are top notch, I've heard, although they don't have the capacity to load much steel shot. |
I myself like federal brass. Its true, primer pockets get loose quick. But I find my most consistent accuracy and velocities are usually with federal brass.
