[QUOTE="Dean2, post: 1853214, member: 26077"] On 22 Hornet and 218 Bee brass deburring the flash hole definitely makes a difference in group size. So does using pistol primers instead of small rifle primers. In larger cartridges I do it on domestic brass, not on Lapua as their fl;ash holes have no burrs. I can't prove deburring the larger cases actually works because I have never tried 10 done and 10 not, fire for group. It for sure doesn't hurt and based on the results in the Hornet my bet is that it does at least some good. [/QUOTE]
