Hammer Bullets compressing my powder charge.

[338 dude]

First thing I would do is measure where your bullet contacts the lands in your rifle using a Hornady OAL tool and a modified case. Then measure your magazine for max COAL that it will hold. If your magazine allows you to load long enough to hit the lands in your rifle then then start with around .020" jump. If your magazine doesn't allow you to reach the lands then load to max magazine length that still allows proper feeding and function of the loaded round. Then work on powder charge

And when you find your pressure limit with powder and back off to an acceptable amount if accuracy is still not acceptable work backwards from maximum mag length many bullet shoot just fine with an extremely long jump

I didn't see any phone # on his website.

I could be wrong but I believe Steve @ Hammer said they used Nosler manuals as their starting point and worked from there.

That's another good manual my favorite

with this bullet the max oal with the Hornady gauge is 2.77 I set it to 2.66 even if I used the 2.77 the bullet is so long being a 145 ga the bullet is about .5 into the powder. I am going to try the 117 gr. I don't know how this bullet can be used in 270 win I have to remove all the powder but 40gr for it not to be compressed and the is way under min charge

I don't know where you got the idea I was talking about velocity. I was referring to the Hornady reloading manual tenth edition page 354 win 760 the top of the list that goes from the fastest burn rate to the slowest. When I said the the bullet would still compress the fastest powder. I didn't say anything about velocity.

it was the way you worded it. Made it sound that way. But I'm glad it wasn't that way.

Some compression isn't necessarily a bad thing. What is your over all cartridge length from the base of the case to the tip of the bullet, without the Hornady comparator?

Also, without checking bullet seating depth to lands, you can't just use what your seating die is already set up for.

And since you gave no data on powder, charge weight, brass, etc., hard to give better advice other than don't blow yourself up.

Agreed! Way too many uncertainties/mysteries in the OP's reloading process.

You need some help, you don't know what you are doing. If you don't want to answer the questions being asked, you need to have someone you know that is more experienced help you.

I guess you did not read my post in #47. I use a longer bullet without any issues. "IF" you only clarify some of the relevant information that most of us are asking, it can help your reloading process tremendously and most importantly, safer.

Is the 2.77" COAL or CBTO? If the max is 2.77", why would you set even deeper to 2.66"? Do "us" all a favor (including yourself), eveyone here is trying to help you but you need to take the time to do some relevant measurements and re-post.

First I did check bullet seating depth and have with this bullet using the hornady comparator it is 2.77. The brass is win the powder n165 59gr max is 59.9 the bullet is shock hammer 145gr.

Have you done any load development or just threw a bullet on top of a powder charge. As with any all copper bullet, they will be longer than a cup-n-core if the same weight.

CBTO I set it deeper because I haven't loaded copper bullets before and thought covering up all the bullet rings was a good place to start and I could adjust it latter.

I just got a chance to look at that bullet you will be seating very deep due to the bullet design I suggest you go to a faster burning powder or go to the 117 hammer hunter it should be a great bullet for the 270win.

I have loaded for this rifle for years and this powder charge has worked for all the 140gr and 145gr bullets i have used so I thought it would work for this 145gr bullet.
