To avoid bullet break-up at close range, consider using a bonded-core bullet in that .300RUM, like the Swift Scirocco or a bonded-core/partition-style bullet like the Swift A-Frame.
I've never gotten less than 90% weight retention in bullets recovered from large game such as eland, wildebeest, and Cape buffaloes.

Shoot straight, shoot often, but by all means, use enough gun!

I would be wary of shooting round nose bullets from a 300 Ultra at big animals.

My reason for thinking this way is that the round noses in 30 caliber are probably designed with the 30/06 in mind.

You could email Sierra or Hornady and ask them as they normally reply within a few days. As a bonus, after you email them Sierra puts you onto an email list for news bulletins.

As to round noses themselves, I love them.

My 338-06 AI likes Hornaday 250 gr RN better than any other bullet I've tried (and I've tried almost everything available). My load shoots that 250 grain RN -1.5" at muzzle, 2.4" high at 100 yds, 0.0 at 200 yds, and 10.1" at 300 yds.

I am a realist. I do not attempt shots longer than 300 yards. I regularly shoot the 380 and 450 yd silhouettes at the range but I won't attempt a shot on game at those distances.

Many people do, however attempt shots at distances past 300 yds. Maybe they need spire point bullets but they sure as heck don't need a boat tail. All a boat tail does for you is rob you of powder space. The long, spitzer boat tails sell so well because a loaded round looks very much like a Nike missile. But that is all the advantage they offer. My grandfather shot to many hundreds of deer with flat point and round nose bullets, near and far, for me to think otherwise.

I truly believe in the RN bullet. Just ask the man at Hawk bullets. He'll tell you that a bullet can be made to perform perfectly on game easier when designed as a RN than when designed as a spitzer. He will also tell you that, with his bullets, your trajectories won't be that different either. Trust me. He's right.

You must have done more shooting than reading

The Australian Hornady agent will tell you that the buyers of round noses all have one thing in common....lots of field shooting.

Mike

Why then did Remington discontinue the Roundnose Corelokt??? Their customers must read more than they shoot...

You are right about wind deflection. If you are in the situation where you have an absolute 90 degree cross-wind, you will have roughly twice the wind deflection with a round nose as with a spitzer of the same weight and at the same distance.

On the other hand,

I use the 338-06 with a 250 grain round nose. It has a relatively high BC. If you are shooting a 150 grain 30 cal spitzer soft point at 2900 fps in a 30-06, a 20 Mph cross wind will move your bullet approximately 15 inch over at 300 yards. My 250 gr. 338 moving at a lowly 2600 fps will be moved approx 20 inches over at 300 yds.

With either shot, compensation will have to be made for wind deflection. 5 inches of difference isn't enough for me to risk proper bullet expansion and penetration by using a spitzer.

Mike375,

I've done some reading.

Easier to make expand reliaby.
Necessary for tubular magazines.
Heavier weight can be stabilized in slow twist barrel.

Roundnose disadvantages:

Not as aerodynamic, meaning more drop over a given distance, less energy at a given distance, and more wind drift at a given distance.

Everyone has his own idea of the distance at which roundnose disadvantages outweigh its advantages, but most would agree that it doesn't matter at less than a hundred yards and matters a lot at more than 200 yards.

I personally just don't have any use for a roundnose because almost all of my hunting offers opportunities at more than 200 yards.

Shawn

I agree with you actually. I thought I would be a bit of a smart arse. Actually, though I think that a flat point shocks a little better than a round nose though, but I am not certain if it makes much of a difference.

When I said long range I meant loooong range say 800+ yards. At those yardages the boattail is advantageous. The bolt tail improves stability at subsonic velocities, which are attained at loooong range. For 400 or so yards you are right the boat tail serves no purpose and is a powder space reducer.

I use that 250 RN with 4064, at 2600 fps. The deer I shot with it was standing towards me at 120 yards. The bullet went in through the center of the heart, drove in a straight line, and out his hip. I never recovered the bullet, darn it.

When I removed the heart, on the entry side, there was a perfectly round .338 cal. hole. On the back side however, there was a hole about an inch and a quarter in diameter. This shows how quickly the bullet expanded to full dia. Furthermore, the straight path and exit through bone means substantial weight retention and terminal sectional density. I could not have been more pleased. In fact I am going to be doing some penetration tests of many different bullets and building a website pretty soon to display my findings.

I'll keep using the Hornaday 250/338 RN.

The American public is is so obsessed with speed and pointed bullets that the sales of the RN Bullets has all but "died".

I'm surprized that Hornady and Sierra still even make them.

On the other hand, those of us that have used them, love them.

It�s annoying that there aren�t any RN:s at all in .222"...

Most seriously,

Fritz

If you mean in .224" I used to load the 55 gr Sierra semi pt in my .222 Remington. This was to get more "killing power". This was a long time ago before there was a Blitz or a Hornady SX made for those velocities. I don't know if that bullet is still made or not. For sure I was just guessing then.

I have some Speer 70 gr round nose bullets in .224. The box looks quite new but I don't recall when I got them or if they are still made.

Yes Don,

you�re right: so I mean. I�m going to have a look at the bullet you suggest.

Fritz

Hornady bullets .338 at 2600 fps 100yds zero 15mph cross wind.

range,,,,100,,,,200,,,,,300,,,,,,400
trajectory
RN,,,,,,,,0,,,,,-5.1,,,,-18.8,,,,-43.7
SP,,,,,,,,0,,,,,-4.6,,,,-16.4,,,,-36.7

drift
RN,,,,,,,,2,,,,,,8.2,,,,,19.7,,,,,,37.3
SP,,,,,,,,1.3,,,,5.4,,,,,12.5,,,,,,23.3

I'll use a well made SP over a RN anytime

Sorry about all the comas but it just wouldn't leave the spaces in when I submitted it and there I was thinking that microsoft word was the most frustrating program I had used.

Your figures leave out to vital points.

Firstly, checkout how small the extra distance is before the Spire Point has dropped the same as the round nose.

Secondly, my experience has been that the spitzers don't always deliver the quoted ballistic coefficient.

Undoubtedly nose damage could contribute.

But I think what also happens is that the sitzer often gets a bit of a wobble up and that wipes out a lot of ballistic coefficient.

Remember that extreme range target shooting is done with rifles where the twist rate is only just enough to stabilise the bullets. I think twists that are too fast are inclined to cause spitzers to wobble for a while.

Mike

uhhh. I guess you saw the figures before i put all the comas in. I looked at the traj figures out to 800 and the sp just keeps getting better, the RN drops 78" more than the SP at 800.

You may be right about the drop figures for the SP I may one day do a test.

Could I borrow your chrono to test remaining vel at 800

What I meant is, that let us say a round nose drops 18 inches at 300 yards and the spire point drops 12 inches at 300 yards.

You will find that the Spire point will be down 18 inches at not much past 300 yards.

In fact it takes a huge difference in muzzle velocity to gain 50 yards.

I have never chronographed bullets at anything except 15 feet range.

But my general observations based on bullet drop and shooting steel plate lead me to be very suspicious of quoted ballistic coefficients of spitzer bullets used in what amounts to twist rates that are far quicker than required for the bullets.

The bullets I have shot the most where both spire point and round nose are used is the 270 grain Hornady 375 bullets.

I have used the 375 since I was about 20 and am now 53. If shooting roos and pigs is a sin with 375s, then in hell I will be for a long long time

Some rifles will shoot the Spire better and some riflesmight shoot the Spite better with certain powders. So I have, I do and I will continue to use the Spire.

But for me at least, the 270grain round nose has given better result at all ranges tha the Spire point and is my bullet of choice.

As I said, some time certain 375s will do better accurayc wise with the 270 grain Spire with certain powders etc. so sometimes I am forced to use the spire point.

Lastly,when measured against many years of use, where bullets are changed by manufactures for different reasons etc., the round nose just seems to be the most consistent.

Mike

I have always found that both Hornady 270 round nose and spire points work well on roos, as have other shooters I know who use them. Low chest shots and gut shots are often quite devastating.

As to wind, to me they both seem about the same.

But I guess I find wind out west a bit like distance. The animals seem tobe inside 300 yards or way out further. At 300 and less a 308 or wahtever is fine and way out further you are holding over no matter what the caliber.

Wind seems to be the same as well.

The conclusion I came to years ago was that there was not much real world difference between calibers, so use what you like was the best.

But one thing that is strange.I have used the 270, 308, 300 Win and 375 more than anything else.

But my "hits to shots fired" have probably been better with the 308 and 270.

The only explanation I have is that with the shots out towards 300 yard you are starting to do some holdover with the 308 and 375 and perhaps this just better equips you for the much longer shots.

Don,

I have seen these Speer 70 grain RN, but never tried them, as they are rather heavy. Did you ever try them in your .222" Rem? Did they stabilize? And if so, with what powder load?

It would be a ideal bullet for roe deer, if I could fire it in my BRNO .222".

Best ragards,

Fritz
