How short of a barrel is speer gold dot 223 effective?

[WS6]

Technically, they wouldn't refuse to sell anything. I believe I was told that they will typically recommend an American Eagle equivalent load for training if a .223 duty round is sourced.

But I mean, they discontinued it, right? It could get used in a .223 chamber! The only safe way, is to discontinue it, along with M855, just like they did the Gold Dot 5.56...

See what I mean? The story is what it is, I know, but it doesn't hold up for beans in the court of common sense, IMO

Business decisions and common sense rarely go hand in hand...

That is complete BS. I am not saying that that isn't their CLAIM, but it's bogus. The real reason is that when you push the Gold Dot faster, you end up with worse terminal performance due to increased fragmentation due to the "softer" design of the projectile.

The reason that I assert this claim as bogus is that I can waltz right down to Cabela's in the morning and buy as much American Eagle 5.56 pressure XM193 as I want. There is very little logical basis for the above claim, in light of this.

That is exactly what the ATK rep told my agency as well.

However, i agree with you for the reasons stated. We can see the limits of projectile structural integrity when fired from 18+ inch barrels into gel blocks at close range from the .223 pressure loads.

How does the 55gr GD compare? Picked up a couple hundred rounds for a song recently.

More velocity would be nice but its not a deal breaker for me. I would care more if I had an optic with a BDC reticle but since Im running an RDS its a non issue, I just need to confirm at range and know my hold overs. The 75gr allows me to throw more mass downrange and get expansion out to 300 yards without breaking the bank especially since heavy OTM 5.56 and monolithic coppers are more than 2x the price.

What? No. The 75gr gold dots are only cheaper right now on sale at PSA, normally and everywhere else they are $1.00+ per round, unlike mk262 clones that are regularly $0.60 - $0.68 a round.

If that is true wouldn't it be best to stick to 64gr for SBRs to keep the velocity up beyond the expansion threshold as long as possible?

Bump - as I would like to know the answer to Eurodriver's question as well.

Yes, the lighter the bullet, the higher your muzzle velocity and thus the downrange velocity will be higher also, up to a certain point...which extends your effective range (terminally).

According to DocGKR, you want the heavier bullets for fragmenting OTM construction, whereas you can be effective with lighter bullets that are of an expanding design. IOW, it's not necessary to have heavier bullets if it's a barrier blind (expanding) round.

IMO, 62-64gr is a good balance between velocity/weight/effective range/ect. for a round like the GD. Going lighter or heavier should depend on what performance envelope you want to attain.
