[QUOTE="DUSTY NOGGIN, post: 2292403, member: 89550"] no, consider the cartrige you have, has a minimum sammi headspace .. the full length die when bottomed out on a standard shell holder is supposed to size the shoulder to the minimum sammi height to fit in any gun of same cartridge chamber.. lets call that zero most chambers (except yours ) will chamber and fire a minimum sammi cartrige .. but the once fired brass will swell to match the actual chamber size of each and every gun .. that once fired measurement will be somewhere beteeen the zero we stated earlier and +.010 longer than sammi minimum (zero) .. sammi headspace tolerance once you have measured your once twice or 3 times fired brass you will know how much it will swell to fit your chamber the objective is to be .002 shorter than the swollen once fired chamber measurement in your case the Redding comp holders will not help you is your shell holder the same brand as your die set ??? that is why people are suggesting taking your easily replaceable cheaper shell holder and sanding down the top the .002 more that you say you need to get em all to fit but before you do that you will want to soot or ink the brass and see that it is in fact hitting on the shoulder when chambering , and not contacting at the case mouth due to carbon ring or lack of trim clearance or you may need to remove your ejector plunger from your bolt when checking the fitting.. to feel if it may be wedging in the side wall i find it odd when this happens.....because it adds so many more possibilties in a perfect world all once fired brass should be in bewteen the headspace tolerances for the cartridge.. its weird when yours is shorter . that means that some factory brass wont fit your gun [/QUOTE]
