This always makes me wonder how people successfully reload this round (I know that they do) if they don't glue it. I would think that there would be set back issues with just pressing it in.The only observed round that has a crimp was some older L191 I came across. All 5.7 FN ammo has glued bullets.

yeah, I discovered the same. I was skeptical at first, but I had to find out and even ponied up another $30 to buy another box of SS197 SR so I can pull apart one of them to see if indeed the V Max projectile was only glued in.Just found out Shockingly that the SS197/blue tip has the bullet glued in, not crimped so I wonder if my SS192, SS196 is glued or crimped? I know the SS195 & SS198 are Crimped!
The few times I unloaded some 5.7 mags I had 4-5 of the blue tips break off tips of blue plastic usually at least 1/4" or more per mag, hopefully the glue wont fail and the bullets drop, it is enough worrying about the life-span of the lead primers and now about Glue melting!I hate the plastic tips. They melt and make a mess in the flash hiders and especially suppressors. I really can't find a purpose for them other them to supposably help with "feed issues".
No need to. A buddy of mine who reloads 5.7 also told me yesterday that glue or crimp is not needed. The neck case will be pinched back down from resizing in the die and the neck pressure from the resized neck diameter will be more than sufficient to hold the projectile in place.Makes me wonder if I should get 1 and crimp all my ammo about 2K (OMG!) however if I had a prob with any FN would not honor any warranty and say it was reloaded ?
Excellent info :?I either very very lightly crimp or glue my 5.7 loads. Normaly, I do not find neck tension to be sufficient. If I can push the projectile into the case by placing the round nose down on my reloading bench and pushing down on the round, then neck tension is not sufficient.
The use of the adhesive by the factory loaders also plays a part in the slight delay of the projectile being released from the case allowing a faster pressure spike on tbe burn curve.
The adhesive is not solely used for bullet retention IMHO or in my observed findings. So I crimp very lightly or use a home made adhesive. The Markron works OK but is time consuming for little return.
