    Hi,
    I use neck sized fire formed cases in my No4 MK3 and I have never had a problem.
    In fact, I have never heard of the one you mention.
    If a case is tight it is usually because the breech pressure was too high in the first place.

    The only thing you have to remember, (if you do not already know), is that cases stretch everytime they are fired.
    Watch out for a shiny ring near the head of the cartridge, it indicates that the case is getting weak and will seperate eventually.

    do you trim your cases to make sure there the right length if they get abit long that isnt going to help chambering rounds.

    20 years of neck sizing for 16 Enfields and I've not broken anything yet.
    Once the cases start getting a little tight to close the bolt, I ever so slightly bump the shoulder back a little with a full length die, check the length, and trim to 2.222 if needed.
    I also do the bump regardless, for ammo I load for comps to make things a little smoother.
    15x 303s, 1x .223, 1x 7.62, 1x .308, 8x .22s, 1x7.5, 1x30-06, 2x.357, 1x45-110, 1x45acp, 2x32-20, 1x.50, 2x12bore, 1x 357lbr, 1x .22 lbp and some others... 42 currently :-)

    Whoever told you about the extractor snapping/chipping is confusing handloading with loading by hand. If you use your Enfield as a single shot a lot without using the magazine it can lead to extractor damage. Necksized cases can't and don't cause damage to extractors.
    The South of England has 2 good things, the M1 and the A1. Both will take you to Yorkshire.
