Hammer Bullets compressing my powder charge.

This is why I dont go to public ranges...... never know who's at the bench next to you! Please take the advice that many of these members have told you. We dont want you to hurt yourself or someone else. Those rings are not seating depth lines!

Feenix guided me to looking at the Hornady data and it does spec 59.9 as a max for a 140gn bullet so still believe 59.0gn of N165 is a bit hot for the 145gn bullet and could be compressed with the mono.

Agreed, esp., if he does not have a good grasp on seating depth.

Sorry but "if" this is true, you should know that your statement below is not true and you would not be having this issue. One thing I learned early on is that there is always someone far more knowledgeable and far greater real-world experience than I am. Most of them are always willing and able to help. "If" you are receptive, you will learn a lot as I did ... and continue to do so. Knowing just enough can be dangerous to you and others around you. There is no substitute for safety. SAFETY, SAFETY, SAFETY!!!

Start over with load development like (dirthead1) suggested . A full work up will answer and relieve any concerns you may have about it.
IMHO

A person can have 30 years reloading experience OR 1 year's experience 30 times over. I was the former before following this forum over the years and paying attention to the advice offered here. It's really easy to make an assumption that is seriously wrong and not know it.

I did read the whole thing and not to be rude, but it doesn't seem like you entirely know what you're doing. That is why I think you should read more loading manuals and do some more research before you hurt yourself or your rifle. You can't use the same powder charge for every bullet you intend to shoot. Also seating the bullet based on looks because of the rings on it is a terrible practice. I seriously don't want to see you damage your rifle or hurt yourself.

Yes what you are saying is correct but you are missing the point or maybe i'm not explaining myself so let me try again The CPTO using the Hornady COL gauge is 2.77 I am hitting powder when I install the bullet at 3" so when I install the bullet to 2.77 the powder is being compressed by .3 of an inch and I cannot reduce the powder charge low enough not to be compressed. That would be 40gr and under min charge.

I think you have more powder in there then you think you do...dump it and weigh it.

Quit using the Hornady tool and measure your COAL and compare that to SAAMI.

LOL! Can you say "social distancing"?

What is the maximum length (COAL) your magazine or internal box mag can hold? How does that length compare to CBTO of that bullet to your lands? That's the first thing I do when starting a load is figuring out max COAL based on my rifle and CBTO to the lands. Then, I start load development at the longest length possible (based on my rifle) at a low charge weight and work up. AFTER finding a node I do a seating depth test to determine the best COAL that works in my rifle and will feed from my magazine. That's where you need to start.......from the beginning.

Also, don't assume that the same weight of one power will fill the case exactly the same as the same weight of another powder. Finer/smaller kernels will pack together and fill less internal space. Larger kernel powders take up more case space for the same weight. You can use drop tubes to get the powder to pack together in the case a little better. You just need to go back and actually start from the beginning. That bullet might be fine in your rifle if you just do a proper load development, but I get the feeling you don't know what that actually means. Again, you are trying to go from point A to point Z without doing any of the work required to get there.

If you don't know how to do load development, just say so and many of us will be more than happy to help.

You should read this whole thing and you will see I know what I am doing.

Sad to say, no you don't. By simply seating the Hammer bullet till all the rings were inside the case proves that you don't. Copper Hammer bullets are a whole different animal than what you have worked with in the past. Stop-Read-Start Over

I think his problem is this ...

I am using 145 gr shock hammer. I put the bullet in to cover the top ring and the powder is 59gr

"IF" he is using the top ring of the bullet to seat his bullet, it is too deep. I cringed just thinking about it.

As Creedmoor shooter noted, the rings are not seating depth lines/indicators.

 

[Korhil78]

LOL..holy crap! That picture says a 1000 words! Can you imagine seating that bullet that far in! The mental picture of it so far down in the case is pretty funny to imagine though.

 

[Korhil78]

Would have been even better if he was loading for a 270 WSM though

 

[Creedmoor shooter]

Looking at that bullet, I'm trying to imagine stuffing that much bullet into the case.
