Hammer Bullets compressing my powder charge.

[19 Badger]

At least the OP did stop and think about it and ask before firing it. That would've been bad, nobody wants anyone to get hurt. That loaded round had to have looked odd tho. Lol.

That Hammer bullet is not much longer than the 150 Berger (1.294) and is much shorter than the 170 Berger (1.49) Something is not adding up here.

Good read here.

You need to use your Hornady OAL gauge and measure max coal with that bullet. Come off 50 thousandths from there and check to see if it fits in your boxmag, this will at least give you some type of reference starting point. If this fits or doesn't you can adjust from here. I know guys that are shooting the 170 Berger out of their 270 and have no issues and for many of the powders used they're starting load development in the mid 40 grain area. Here is a load development card used for the 170 Berger. Good luck and keep asking questions. Better to be safe than sorry.

You shouldn't just throw a charge that works with another totally different bullet. That is asking for trouble. Maybe look at the Barnes book to get an idea.
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.

If you are compressing powder that bad, I am betting something is way wrong. No way is max COAL 2.700". The case alone is 2.540" max. Unless you are talking .270WSM. But saying ".270" usually means ".270 Win" in the shooting circles.

If you mean ".270WSM", then 2.750ish would be correct for a SAAMI round. But until you do a seating depth check, you don't know where your bullet to lands length actually is.

How do you know N165 is "the best powder for the rifle" if you are just starting to reload for that 145 Hammer?

My thoughts exactly but what confuses me is that a 270 WSM should hold a tad more powder than 39 gn.

He isn't shooting a 270 wsm. He is shooting a 270 Winchester.

Agreed! That's why I made the comparison with 175 Matrix on #47.

Might not if ...

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

9 pages of speculation and no answer. I think one picture could have given us the answer. But everything is closed so this is entertaining

Sad but true!

OP doesn't want to admit his failure of wisdom.

I am reloading hammer bullets for the first time and when I install the bullet in my brass it goes deep into the powder. I have only loaded with lead bullets to this point and have never put a bullet that deep into the powder. I am loading for my .270 and using N165 it is the best powder for this rifle.

I just replied on another forum topic about what I am going to mention to you. How do you know N165 is the best power for your rifle? Did you read in the book you are loading from that it's the most accurate load tested or are you looking at the fastest load? If you are doing either one is your rifle identical to the test rifle the published loads are derived from? Or, is the twist rate identical or barrel length? What you might find is your particular rifle likes totally opposite loads that the test rifle does. Regarding compressed loads, while I have loaded and shot some with excellent results, I always reduce my starting load 10% of maximum loads published and work my way up to the tightest group.
Hope this helps.

Gotta give the OP a little credit though. He stopped and asked. So "good job" for doing that. Now just take some of the constructive criticism you've received and apply it.

 

[WWP2012]

I just read thru 9 pages of solid advice and the OP being snarky in his posts. He hasn't taken any advice, tried it, and reported back with the result. He is trolling from being bored or trying out for a Darwin Award. Either way seems every one trying to help would be better just talking to a wall.

......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 loaded the 145 Shock Hammer in my son in laws .270 Winchester. It's one of the easiest bullets I've loaded for, 12 rounds to a working sub MOA load with meat on the ground.

1) Erase the board for what you have stuck in your mind.
2) Build a dummy round-just case and bullet.
3 Seat a bullet so it fits comfortably, but use available magazine space.
4) Place it in the magazine, and cycle it. If it feeds without resistance were home for now.
5) If there is resistance, and it's not from the case itself, seat just a bit deeper until it chambers easily.
6) Now you've got it seated its overall length from base to tip will measure about 3.3".
7) Primer
8) Charge 4 or 5 with the minimum load listed in whatever manual you are referencing. Likely 52 grains plus or minus.
9) Range trip, firing one at a time, check for ease of extraction look at base for unusual marking. If good fire a group with the 4.
10) At home look at cases again-think about your goals. If everything looks, feels good consider adding another grain and repeat.

I'm out.

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

This is a max load for cup and core bullets not mono's. Vihtavuori lists for their N165 in a 270 Win:
52.8 gr. MAX w/ 140 Barnes mono and 50.5 gr MAX w/ 150 Barnes mono.
