Just an FYI, but all of the sheets on that Excel spreadsheet were attached also. I'm not sure if you meant to do that or not.

On the rifle loads, are those loads you concluded were accurate out of the respective rifles? If so, what size groups were you typically seeing with each? I'm interested because there is is an obvious velocity difference between the bullet types even with same weights. I find this interesting. I've always held the premise that every bullet/powder/rifle combos need to be treated as an individual set of conditions and have to be tested to find their optimum conditions. If the 300 WM data is all from the same gun, the velocity differences (and standard deviations) between the 180 gr bullets are interestingly spread apart.

The 185 Berger (hunting bullet?) averaged 2891 fps and between the three powders has a standard deviation of 13.5.

The 180 Nosler (Partition?) averaged 2950 fps and between the three powders a SD of 48.5.

The 180 SGMK (Sierra Gameking?) averaged 2927 fps and SD of 38.6.

Just based on the SD numbers, I would suspect you are seeing the best accuracy out of the Bergers and the least out of the Noslers. But neither the Nosler nor the SGMK are even close to the consistancy of the Bergers. Does this ring true?

Assuming you looked at the figures on tab [WEBLoads], I'm curious how you calculated Standard Deviation. Excel gave me different numbers than what you have. In any case, it's useless data, as each shot has a difference amount and type of powder.

I used an N-1 degrees of freedom instead of a basic n value. It doesn't matter which was used as the comparison would still be valid as long as the degrees of freedom was consistent. Granted though, the sample value for each is only three, but that should be enough to look at and speculate.

I did pull the data off the WEBload sheet, but the data may not be useless as long as the loads were the most accurate loads of each combination for the gun. As I stated in my other post, for a single gun the powder and bullet combo for that gun is going to show some consistent desires for accuracy. For example, my Rem 700 PSS shoots a 175gr SMK bullet the most accurate at a velocity of 2730 fps. This is a different charge of powder between Varget, IMR 4064, and RL 15. It's even a different powder charge if I switch from Lapua brass to Win brass. But, the velocity range in which it's going to shoot the bullet accurately remains fairly consistent.

Looking at the SDs of the different bullets is a representation of the differences in the gun and powder relationship with the same bullet. Where the velocities of different powders all preferred a very consistent window of velocity, may or may not point to a consistently more accurate bullet/gun combination. That's why I asked for more info. I want to know if this rang true or not.

Ok, here's the deal on the xls...

I started that sheet back in 2005 when I first got into reloading. Instead of having hundreds of different xls's for every gun and all the other bs, i lumped it into 1 xls file.

So, I still have not found the magic formula for my savage 112 in 300wm. These are not accuracy loads for any given rifle, just different velocities out of the different guns. I'll post more when i recharge my battery...

Well, I picked up the rifle today. Got some factory ammo for now so I will shoot that and get it sighted in and ready for hunting season. then I will figure out some loads to work up based on some of this data!
thanks guys

It's all good. I like looking at stuff like the above. That's all. Since the data isn't what I suspected, the above isn't really going to show any trends.
