Re: Why not lazzeroni rifles?

Not to hijack this thread. I would really like to see Kirby start a thread on detonation. I think that I have had some dealing with this. I would like to know why.

Re: Why not lazzeroni rifles?

Thanks for the input Kirby. It sounds like your 300 AX Has slightly less capacity than the Imp version I described? And to make clear regarding RL33, it works much better when using heavy for cal bullets such as the 30 cal 230 Hybrid.

John, I am not your "pal"

Being a sponser here, I think you would do much better to be a little more professional.

Once again, you have strayed from discussing to facts and figures into bluster, patronizing and personal attack. Your post has zero info in it pertinent to whether or not lighter bullets are more efficient and accurate than heavier bullets and whether or not your Warbird brass is the only brass in it's class to give that level of performance. The plain and simple truth is. it isn't.

Lapua brass is better than your Hornady made brass period. And the Imp Lapua is essentially the same capacity as the Warbird. That's a fact that Kirby has shown us in his comparison and a fact the case spec dimensions clearly show from a mathematical view.

More facts... heavier bullets are more ballistically efficient than light bullets, especially when it comes to hunting. You only need to punch the numbers into the calcs to prove this.

Thumping my chest? Really? Would you care to point out any statements I made that would be "thumping my chest" or "bragging"? Have you gone back and read your post? This is what I call bragging and chest thumping...

I would like to go down to Arizona and shoot with you guys, but I wouldn't be betting anything more than dinner and beers and would be glad to buy. that said, I have other travel priorities if i do travel. However, I would like to extend the same invitation to you and maybe we can stretch it out to a mile or more shooting steel and killing rocks. It gets a little windy up here but don't let that scare you and your 150 gr bullets.

BTW, this isn't a popularity contest. It's about the facts. And whether or not I out shoot you and your gun or you out shoot me and my gun also proves nothing. This isn't about the quality or accuracy of your rifles or my rifles. I'm sure you have and make fine rifles. Like I said, I would be glad to do a little challenging and fun shooting and glad to pay the dinner and beer tab as well.

I true 338 Lapua Improved does have slightly more capacity then my design but the difference is really minute. 1 grain at most difference.

That said, the reason I put more taper into my design is simple, more body taper enhances extraction with top pressure loads, ESPECIALLY if there happens to get some dust in the chamber which certainly can happen out in the field.

The reason for it is more function then performance, or should I say, better function at high performance levels.

[QUOTE=MontanaRifleman;

Have done ALOT of load development and ballistic testing with big magnums ranging from 25 cal up to 50 cal. Looking over my notes I have found some interesting data that supports Marks comments in a couple ways. Let me offer some of these results. Since these are with my wildcats and this post is about Lazzeroni products, I will not mention my wildcats specifically.

First example is my 25 cal wildcat which is based on the 338 RUM, necked down and fireformed to my shoulder and body taper design. This is certainly a hot rod capable of driving a 100 gr bullet to a legit 4100 fps. That said, with the 100 gr bullet weights, does not matter if its a ballistic tip, Partition or Barnes TSX, about the best extreme spreads you will get for a 10 shot string is in the 25-35 fps range. Not bad. 500 yard accuracy with best loads for the test rifle were easily in the 3/4 moa ctc range for three shots at this range. THere was the occasional 1/2 moa sized group but can not say these loads would average this size groups. Again, not bad at all and in all honesty, I was stoked when I got this level of performance. That said, I was about to learn a valuable lesson with this testing.

I then switched to a custom 156 gr ULD RBBT made by Wildcat Bullets specifically for this big 25 cal magnum. Compared to the laser fast 100 gr bullet, this one is pretty poky clipping along at an average velocity of 3450 fps., that's more then 600 fps slower then the 100 gr bullet.

Interestingly enough, I tested H-870, AA8700, WC860 and WC872. Every one produced top loads that had Extreme Spread numbers between high single digits to low teens...... Add to that, 500 yard accuracy was also noticeably different, Average three shot group size was was just a hair over 1/3 moa but in doing accuracy testing over several different shooting sessions at 500 yards, I shot numerous groups that measured between 0.880" to 1.130", roughly 1/5 moa.

So, with the heavier bullet, Extreme Spreads dropped DRAMATICALLY as did group size at distance.

Now, to test this even more, I tested this at 1/2 mile (880 yards). The Hyper speed 100 gr bullets all produced groups in the 3/4 to 1 moa range in good shooting conditions. In slightly windy conditions, groups averaged in the 1 to 1.5 moa range simply because the wind was having its way with the lower BC bullet in spite of its hyper velocity launch speeds.

The relatively slow 156 gr ULD RBBTs on the other hand EASILY held WELL below 3/4 moa and there were several groups between 1/3 and 1/2 moa in size. While calm shooting conditions produced the best groups overall, even in the windy conditions, the group sizes were smaller then the 100 gr bullet groups when those were shot in calm conditions.......

When your dealing with large capacity magnum chamberings, the heavier the bullet you use, the more consistant your powder ignition will be. The resistance of the heavier bullets just improved ignition and powder burn which translates into tighter Extreme Spread numbers. The slower the powder used an the lower the expansion ratio of the chambering being used shows that the heavier the bullet the better the results.

These results have held true for 6.5mm, 270, 7mm, 300, 338, 375 and 50 cal. In every case, the heaviest bullets produced the tightest Extreme Spreads for each caliber. So as far as consistency goes and internal ballistics, the heavier bullets produce superior consistency in almost every chambering I have tested where case capacity is over 80 grains of powder charge size.

Now, as far as external ballistics go, the reason that the 156 gr ULD RBBTs shot tighter groups then the 100 gr bullet weights is likely a result of several things, Higher BC value which simply bucks the wind better and better velocity consistency adding up to better accuracy results at long range and even moderate ranges.

Again, this has been tested in every caliber mentioned above and inspite of the velocity advantage of the lighter bullets, and at ranges out past 800 yards, the heavier, higher BC bullets have a clear advantage, even more so then what you would expect comparing the two on paper.

Now, out to 500-600 yards, its a simple matter to flat out HORSEPOWER a light bullet out to these ranges with good results and very flat shooting. Past this range however, things REALLY start to fall apart for the lighter weight, hyper velocity bullets. Anyone that has tried to shoot a small target at 1000 yards with lightweight bullets and then tries it with a heavy weight bullet will or has realized that the heavier bullet just makes hit at longer ranges easier.

This is especially true when your shooting in a location that has unknown shooting conditions such as on the windy prairie or in Canyon country. Much different then shooting on a controlled shooting range that one is very familiar with.

I hate to use the word ALWAY because there are always anomalies that vary from the norm but in 90% of my testing, using a heavier bullet will produce finer velocity consistency. Also, the added ballistic performance of the higher BC bullets will make up for and then some any issue that may come from starting these bullets at lower velocity ranges compared to heavier bullets.

Gotcha, in any case, there is maybe 1 gr difference between the Lapua Imp and the Warbird.

Yep, and seating depth with a given bullet could give the edge to the Lapua Improved or the Warbird depending on what each rifle was set up for throat length wise. They really are extremely close.

In fact, My brother keeps asking if I think he could use Lapua brass to make a short necked Warbird case. The main problem would be the slightly larger head diameter on the Lapua so I told him just to go with the Warbird until be burns the throat out and then we can rechamber if he decides to at that point.

Nothing at all wrong with the Warbird chambering, very potent, its just nothing more then the 300-338 Lapua Improves or the 30-378 Wby. All three are in the same performance class and all are very impressive. AND with the correct twist barrel, ALL perform more consistently in velocity and long range accuracy with heavy for caliber bullets. There is no question about that. Again, as long as the barrel being used has a twist rate that will fully stabilize the bullets being used.
