The 300wby with the 200gr AB shoots very well. I like to use a bigger bullet where I can. The Weatherby is the perfect example of where you can do that. The 200gr AB gives you more energy and only drops two more inches at 400 yards than the 180gr AB. That extra energy is like an insurance policy.
At Nosler we have found that the Norma cases last much longer and are not as undersized out of the box like Winchester brass. We use Norma brass for our WSM ammunition.
Leo M, I am sorry that it is not the answer you wanted to hear, but at the same time, when the 260gr Partition bullet came out, that weight grain was not that uncommon. In the 60's 260gr bullets were more common than they are now.
As to the question posed by dubyam, this is a perfect example of...
The biggest advantage to neck sizing in my opinion is the preservation of case life. This way the brass is not stretching, and then being sized again. A lot of metal fatigue that way.
The Nosler brass is weight sorted to plus or minus .5 grains for every box. Consistency is the easiest way to keep accuracy from one shot to the next. The more consistent you can be from one shot to the next the better. I would have to agree with Val though and say that you probably won't...
It appears that when the .375 bullet was built by Nosler, it was made to 260gr because Federal wanted a lighter bullet. That way they could load it to shoot faster than the 270gr bullets. As we all know, speed sells. There you have it.
Anyone else want to try and stump me on Nosler history...
I am not sure what the volume is on the brass, but I can tell you that the neck thickness is 0.015. Very consistent! I measured it myself.................for what ever that is worth? :wink: The weight of the brass only varies +/- .5 grains per box of brass.
We will not see and announcement for the new brass until the Safari Club show next year. Of course there is always a chance that something may slip out before then............................but not today. :wink:
Thank you for the report. We are very proud of what we do. We work very hard to get it perfect because we know that you the customer will accept nothing less.
That is a tough question. I do not think that anyone can decide that for you. You will have to make your own decision. I personally would shoot it. I hate the idea of having a firearm that you can't shoot.
I hope that we will offer the 338win mag brass. Don't worry, you have a guy on the inside that will be pushing for the cartridge. That is one of my favorites. Unfortunately we will have to wait and see.
The Nosler brass is doing very well. The uniformity of the brass is excellent. Not to mention how much time a person saves using brass that is already trimmed to length, flash hole de-burred, sized and chamfered on the case mouth. The weight sorting is very nice feature as well. You should see...
You should probably check the OAL of the brass each time, but I would wager that you will not need to trim until the fourth time. JD338 is correct about the variables being load type and chamber size.
