 Hornady SP vs. FMJ

I'm contemplating a 6000 bullet box of Hornady 55 gr. My inclination is the SP (2266) rather than the FMJ (2267).

Thoughts or recommendations?

Thanks,

Sundance

For accuracy, the SP is much more accurate than the fmj.
I went for the SP myself. It's what I now use for all my hog and deer hunting in TX.

In informal shooting, I have found the SP to be a bit more accurate. They're not as abusive to steel targets compared to FMJ either.

I've heard (but have never witnessed or experienced personally) some folks get feeding problems with the SP due to lead build up on the feedramps. On the same lines, I've heard the SP is less tolerant of being chambered repeatedly due to deformation of the tip. I have never experienced either of these problems.

Another bullet to consider is the V-max. Good performance on small game, accurate, and none of the possible problems I listed above. They're offered in 50, 53, 55, 55 with cannelure, and 60gr. The 50 and 53gr have a boat tail, the others are flat base.

That new 53gr V-Max has a ballistic coefficient of .290 according to Hornady's website, better than any of the other .224 bullets until you get to the 68gr and heavier stuff.

I've had the same results but the SP flat base bullet is harder to load. The flat base bullet doesnt sit on top the case mouth as easily as the FMJBT. I assume since you will be ordering 6K of them this is blasting ammo...or a lifetime supply of hunting bullets.

Blasting ammo....with hunting or other capabilities. Price is about the same, sounds like the SP is the better choice.

If you champher (how ever it is spelled) the inside of the case mouth a bit, the resulting taper will assist the flat base bullet to more easily enter the case neck.
For flat base bullets, they make life simpler. Such tools are available from most of the reloading equipment suppliers.

For plinking ammo the FMJ is awesome. I grabbed 4 bulk count boxes when they were $370.00!! I get very good accuracy from AR's and my bolt guns.

I have used both, and the soft point would be a better over all bullet.

Not quite as accurate as a match bullet, but still just under an inch in my AR. 100yd, 5 shot groups off a bench.

AR or bolt gun?

My AR likes the FMJs better for some reason. It will put them all touching at 100. Buy a 100 count box of each and see what your gun likes the best then stock up. If your gonna do any hunting with them then go soft point.

In principle, any SP should be "more accurate" than an equivalent FMJ because of how the bullets are made. SPs use "top loaded" cores, so their bases are closed and thus can be very, very consistent. FMJs are "base loaded" so their bases are open and subject to variation in how well they're finished. In practice, Hornady's FMJs are extremely consistent; I don't know if you could actually measure a difference in accuracy between the two Hornady bullets-but it would be fun to test it out.

I bulk load the SP's. I like them and haven't had a single issue yet with them.

I chamfer ALL of my cases before I load them. It makes loading them easier no matter what kind of bullet you are using, but yes it is absolutely necessary when using a flat base bullet.

If you don't chamfer the case mouths the bullet typically gets pretty scratched up on its sides and this can affect accuracy.

Always chamfer your case mouths for best accuracy and easier bullet seating.

It doesn't take much, maybe a half turn with the tool, but it is time well spent as until you trim the case it never has to be done again.

For those of you who are using the FMJs are you loading to 2.200 like the Hornady Manual says or longer.

I load both FMJ's and SP 55 Hornady's. Very slight edge in accuracy with the SP flat based bullet. For the question about overall seated length, I seat both bullets to 2.220" up to 2.230" with no issues in different rifles. The 55 SP would be better for varmints etc. but the FMJ will penetrate much better.

Two questions...

1) Anyone have a good load with TAC for these SP's?

2) Anyone tried the 70gr. Hornady SP's?

I load 24.5 TAC w/ all plinking loads. CCI 41 and any headstamp. This is damn near a standard you will see if you search 55gr w/ TAC on the forum here.

I don't load the hornady 70gr SPs. I load Barnes 70gr Triple Shock (no lead, so larger bullet) w/ 25.5gr TAC. VERY HOT LOAD, work up your own. I ran this up to 26.2 TAC before I started to get firing pin craters.

The SP will probably be a bit more accurate. Nevertheless, Hornady FMJ is pretty accurate for FMJ. Kind of depends on your application, really.

If you get the SP, just make sure they aren't the SXSP (super explosive soft point). These are super thin jacketed bullets designed to explode on target and are used for varmint hunting. They would not be suitable for self defense, and in some cases, have been known to fly themselves apart in 1/7 twist barrels (I have not personally observed this myself, but I've met a couple of folks that saw it happen).

Remember that in some states, it's illegal to hunt with FMJ. Check local game laws.

If I was going to do serious hunting, I would absolutely use the SPs.
