I have log on to post a question twice this week and I see someone has posted the same question only hours earlier. Without hijacking this post I hope I can ask another question about adjusting the powder charge and effect on accuracy. I have read a few times that you should pick a powder that...
With the advice from others on this group I started at .100 and have not tried anything less yet. But I think seating so deep is going to restrict the amount of powder that I can use. With 51gr of RL-17 in my 280AI I'm only getting around 2640fps and the cartridge looks faily full. But...
Here is an interesting article. They mention some starting depth for different manufactures. This might save you a few rounds.

The reason I am trying the Remington 280 brass is because the Nosler 280AI brass is very tight in my chamber. And I saw JD338 was having very good results with the Remington also.
Is it possible that I had high pressure when fire forming the brass and did not recognize it. And now the primer...
I am starting with new Remington 280 brass. I fire formed it in my rifle then trimmed, neck sized and reloaded once.
I can’t say that I noticed if the expander was difficult to pull thru the neck. But I did notice a little resistance from my seating die when lifting the handle after seating...
JD338 your cartridge look very long. For my rifle with a 150 E-tip seated .100 I get a COAL of 3.293. I also think I am compressing the charge of 57.5. at this depth. Does that sound right?

Hi 30-338, yes I'm still shooting the same rifle. And it does shoot Sierra 150 and 130 bullets very well and with no issues with the primer.
I did have good results with RL 17 and the E-tip. But I thought I would stop experimenting with 2 fairly new components until other more experienced...
Dave the brass is fire formed then neck sized. I have to confess that I have not wiped out the chamber before shooting. I'll make that a habit for now on.

I would like to hear any suggestions or opinions you might have. I’m shooting 150gr E-tips from a 280AI, Remington brass, Fed 215M primer and 57.5 gr of RL22. The outside temperature was about 74F.
With the bullet seated .100 off the lands I see some flattening and cratering of the primer...
I hope that after enough request that Alliant will post some test data for the 280AI. I received my reply from the same guy. I’ll paste it here maybe someone could use the info.
“Nosler says the etip bullet require about 2 grs less powder and should be seated from .050 to .100 off the lands...
I'm getting a good education from you guys. That was an interesting chart Woods. The nice part about reloading is we can pick our components to obtain each of our own objectives. I’m turning 49 and this is the only new rifle I have ever owned. I want to do what I can to make it last.
I have started with 47 grs of RL17 (recomended by Alliant) and fired 4 set of 3 shot each. After 2 fouling shot the first group was .100 off the land and each set .005 longer. The .95 look good and I will start increasing the powder charge next to see how that effects the groups. I do not...
Thanks for all your replys. I take pride in the care I give my rifles. But I have been doing alot of shooting these days and I would hate to ruin my favorite rifle.
I just started shooting the Nosler 150gr E-Tip in a 280AI and they shoot great.
Other then my shooting habits and barrel care. What factors affect barrel life? I'm sure heat would be the primary contributor to short barrel life. And this can come from a number of different ways. Like the interval between shots, and the velocity of a round? At what velocity does this...
