What is a tool that is used thats not super expensive to remove primer crimps...Id like to reload these casings and use some for sizing to 300blk. I have tried, unsuccessfully, using a chamfer tool.

I dont mind spending a little, as it would something I would use.

Please share your methods and cost of tool.

I like my RCBS primer swaging die set also. For occasional use, a chamfer tool should work fine. May I ask which tool you were using? The RCBS (made by Wilson)tool is much more effective than the Lee. And you will enjoy trimming cases more.

^^what they said. However, I've had no issue using a Lee chamfer tool to remove crimps.

Mine is a Lee...I tried and still couldn't get primers in there. The end of the Lee chamfering tool is just about too big.

Try the Hornady Primer Pocket Reamer . It removes the crimp and puts a bevel on the primer pocket lip , making seating the primer easier. Chuck it in a drill rather than twisting by hand. Costs about $10 and lasts for several thousand cases.

The tools that squeeze the primer pocket outward work best. The chamfer style tools that shave the crimp work, but require more work and the primers still hang up often when priming. I like any tool that squeezes the primer pocket open and outward, since it puts an even pressure all the way around and helps open up the pocket.

I use a primer pocket reamer, since I already have a Hornady case prep center. I load it on 1 of the 6 stations and do the whole case prep in one routine.

Work well so far.

Lyman handheld reamer, models available for both small and large primers.
I have the RCBS crimp removal set, but have better luck with the Lyman tool.

I bought this all in one hand tool.;gclsrc=aw.ds

Works pretty good for me. I do have some issues with 5.56 military brass every now and again.

I ended up using one of those 45 degree drill bits and cutting away the crimp. Ill go about a second and a half clockwise to cut away needed brass and then about a second counterclockwise...and that smooths it out and makes it look good.
