Has anybody tried and used the FREECHEX III advertised on Handloads .com ? Was just curious. Do you really need them when re-loading for T/C 10" max , or will they fowl up your barrel without the gas check ? Been shooting the RCBS 180 gr. cast for years now., but not lately . Just noticed I was real short on gas checks. Wanted to know about those FREECHEX or homemade checks if anybody had ever tried any ..Anyone ?
