"Be cautious with the exposed lead on some JSP designs. Often they will run great for up to 200-300 rounds, but then mysterious feeding failures will begin as a result of lead build-up on the feed ramps. I have personally seen this occur with a variety of JSP's including 55 gr, 60 gr, and 64 gr in LE training courses. As soon as FMJ or OTM was substituted, all the feeding failures ceased."
I am wondering if this is the case with the Speer .223 62 grain Gold Dot Soft point? In looking at the round it, it seems like the bullet's jacket extends all the way up so that there is no lead on the side of the bullet, only in its face. Hopefully this would prevent it from having lead
Attached is a picture of a Winchester Ranger 64 grain Power-Point soft point (the bullet on the left) next to a Speer 62 grain Gold Dot Soft point.
