The lead bullet is softer, so more lead gets left behind with each fired round, possibly gumming up the barrel to the point of a kaboom. The polygonal rifling in the Glock barrel is what causes this. Jacketed bullets are harder, so they won't leave the lead behind in the barrel to cause this problem.gsat wrote:I have read the posts on shooting reloads in a Glock. I recently purchased 2000 40cal 175 SWC from BulletWorks and had the intention to reload and shoot them in my G35. I now may have a change in heart if these posts are correct. What is the difference in the lead bullet compared to the jacketed bullet? If there is any doubt that failure may occur I will sell these and purchase a full jacketed bullet. If anyone is interested in purchasing these I can bring them to PSC anytime.
Like some of the posts above mentioned, it may be worth your while to buy an aftermarket conventional rifled barrel so you can shoot lead through your Glock with no problems.
