I have read that the cartridge used in the Rem UML are a shortened 308 but they are larger then my #2 shell holder I use to reprime 308 brass. I bought a Lee hand loader to deprime the spent cartridges while I am away on a hunt if needed but I need to know which die and she'll holder works best.
I did deprime some with my 308 die on my Foster press but they were very tight. I have read that I may only want to deprime them twice. I may not need them but I would like that option.
Also. So far I am very pleased with the accuracy. But I still plan on sending it out to Hankins for the sabot less refit.

The cartridge case sizing or length is of no concern. Just deprime them and reprime them. How many times they can be reprimed depends on how well the head space is set. Inspect each piece of brass after its been fired. Any signs of gas leaking and that piece should not be used again. |

Thanks. I was not running through the die to resize them I just wanted to deprime them but as I said the 308 die was a tight fit so I need to go another route. I am going to mic the brass to see if it's any smaller then original.

Maybe just use a small punch to de-prime and not use the die, or use a neck size only die to de-prime them. |

Use a universal decapping die form rcbs. If you want to make you own cases, buy some 45 win mag brass from starline brass, and trim to fit, they have a .020 thicker case head and will close a little tight for a firing or two, but you will get no leakage and they’ll last for up to 10 firings. You can make 100 in an hour and youl have enough to last a long time. Ray

Ray If the case head thickness is .020" thicker on the 45wm than the .308, getting the bolt closed is going to be difficult at best, if at all IMO. I believe you'd have to ream the inside of the case to get the bolt closed, which should be tight. To ream the inside of the case, you'd have to trim all the cases to the same length to set the reamer depth. The 45WM case head thicknesses can vary as much as .005". |

My setup....... Of course with the differences in head thicknesses, the brass must be trimmed to identical lengths before you can set the reamer depth. The reamer is only required if the bolt won't close. s19.postimg.org/hua37x1bn/IMG_0994.jpg |
