Home Forums Hunting & Shooting AR and Tactical Rifles Most lethal ammo/bullet for 10.5" AR 15

62 fusion is a really good bullet, I did not know they would work well out of a pistol barrel. Its not cheap over a $1.00 a round. Anyone know where they might sell bulk bullets (components) of the 62 grain fusion??

Starting velocity,ain't arrival velocity,thus the penchant to add BC to the equation...to retain same.

Hint....................

The 62 grain bonded Nosler can't be all that different from the 62 Fusion, can it?

Thanks guys.

Jimmy, at one time Rocky mountain reloading sold the fusion bullet as a component at a really good price.

Dude, they seem to be out of them now.

When we authorized 10.5” barrels we switched to 75graim Gold Dots to ensure expansion at 300 yards. The Speer loaf is very accurate as well.

They were over runs rather than pulled. I believe that they were selling at 0.13$/bullet. I hope can dig some more up.

several of my 16.5 inch guns are zeroed with the 62 grain fusion, amazing little bullet.

What powder are you using?

At an agency of immediate interest to me, earlier this year, a goblin pointed a pistol at several officers. A SWAT member engaged him with a Colt's Commando 11.5-in. at close range with issued Hornady 5.56 62 gr TAP BARRIER Item #8125C.

The result from a single, high center chest shot was straight down and out bad guy.

Here's Hornady's ballistics with a variety of barrel lengths:

62 gr TAP BARRIER

I buy them preloaded as I cannot find a source for the component, seems like 26-27 grains of TAC, Varget, or RL15 would work if you could find em.

Coldcase, wonder how that bullet performs at 200 yards?? I think most of them close up at 2700 FPS to 100 yards would be fine, but if hunting with an ar pistol and I see a deer at 200 yards, I would want the bullet to expand. 62 fusion will expand down to about 1400 FPS based on what I have learned, this makes a 10.5 inch pistol work a good bit past 200 yards.

Should not one expect to give up something when chopping a 223 to a pistol? Having your cake and eating it toowise?

Not really. Bullets can be, and there are bullets designed to be used from short barrels.

How about the Sig Elite ammo (77grain)?

Those are all good choices &, along with the 75 Hornady, minus the Fusion, are mostly what I use.

But unless one is a LEO or member of some SOG team, I guess I really fail to see the utility of a 10.5" over a 14.7", maybe even for them.

I carry the 14..7" regularly in a vehicle & have no issue at all with handling that length gun in that situation.

What more does the 10.5" really do for me?

MM

fits in a reasonably sized backpack pretty easy.

Not an issue or even a major consideration for me.

Since it's not a gun I'd not need it for a quick-draw encounter & a 14.7" gun breaks down in a matter of seconds, goes together in a matter or seconds & fits in just as small a pack.

For a quick-draw encounter, I carry a pistol or two with extra mags.

MM

its possible though not probable that seconds might count sometime but its just a matter of preference and what your comfortable with, I am not adverse to a 14.7 inch barrel with a fixed flash hider making it 16 inches.

You aren't going to be able to tell the difference in terminal velocity between any of the 75/77gr bullets out of a 10.5" barrel at game ranges. There's likely more difference in velocity between your individual rounds than between bullet types. I've seen ES over 70fps with a SD of about 20.
