    Rookie here, and would like to know what type of crimp for 200 gr lswc should be used. In the process of setting up and will be using hornady nitride dies and power cop die. Is the crimp/seating die ok or should I use a crimp die seperate from seating die. Thanks in advance.

    Rebjac,
    You should be using a taper crimp die as your last station. Crimp (measured at the bullet case juncture) should usually be .468-.470. Through testing you may find your pistol prefers a tighter crimp, but ammo crimped to those specs should feed flawlessly. Don't try to seat and crimp in the same stage, these are two distinct separate process'.

    On an added note, bullet seating depth can be puzzling at first. A general rule of thumb is to leave 1-2 thumbnail thickeness' of lead exposed above the mouth of the case. It doesn't have to be any more complicated than that.
    FWIW

    I've found that the Redding taper crimp die works the best for me on my LnL AP. I shot some 200gr swc yesterday and they fed perfectly. I seated them identical to what Stork mentions above.

    All it needs is a light taper crimp. Just enough to remove the bell or a hair more (001 to .002)

    I used mixed cases so I adjust the die to remove the bell on the shortest and give a hair of a crimp to the longer ones.

    There is so little crimp going on it is easy to seat and crimp in one step, but many like to crimp in a 4th step to make it even easier to set up.

    I load a lot of 200 gr. LSWC....I basically do what Walkalong says....barely crimp them using a Lee seater/crimp die.

    I like to taper crimp as a separate step, but I got into that habit from the days when auto pistol seater dies only came with roll crimps. I still use many of those old dies.

    The Hornady progressive works just dandy for that and fits my process to a tee.

    But, everything else folks have said is valid, so what ever suits you is fine.
