Hi everyone,

I just started reloading and this weekend I took 100 shots of various loads and bullets.
I used Speer Varmint Soft Point (model 1047)
Hornady SP
as well as Nosler Ballistic Silvertip

all 3 are 55 grains.

I used H335 powder as well as Benchmark powder.
I used minimum, happy middle and almost maximum loads.

the Hornady and the Nosler where very accurate and with new stock/bedding and some practice I am thinking I would group them VERY nicely.

the Speer Varmint on the hand was way off EACH and every time, all 3 powder levels.

all 100 casings where preped the same way (lubed, de-primed, priming chamber cleaned, new primer (Same type), inside the neck slightly lubed and bullet seated.

I also tried a few seating depths.

Any ideas?

I am not too worried as I just won't buy them anymore, just wondering if anyone else has had problems with them.

This is why it is important to try severl bullets and several powders and several powder charges at the start. You did exactly the right thing.

It is not unusual for a rifle to not like a bullet. Don't argue with it. Use what it likes.

Here is a plan for testing a new rifle.

Buy 3 to 5 different bullets. I would try 55 and 60 grain bullets.

I tend to start with a known good powder, but using 2 is fine. Your choices of powder are good.

Use a seating depth for the first test of all bullets 20 thou off the rifling.

Load the starting load (5 shots) and then hotter loads in half grain increments (if the full charge is less than 30 grains -full grain increments if the charge is more than 30 grains).

I use 50 round plastic ammo boxes and label the boxes with felt marker on masking tape.

The picture shows such a test. In this case I loaded 10 rounds with each powder increment, being 5 each of two different bullets of similar weights.

This was done with two differnt powders, just as you did.

Now, when you load all teh way up to the max in the book you have to be prepared to come home from the range with unfired ammo. Stop when you get ANY sign of pressure.

Start loads. I saw a rifle that blew the primer badly withthe start load. Each rifle is diferent. My 22 Hornet shot terribly, even after I tried every load and trick in the book, until the day I accidently loaded ammo 5 grains too light. Shot great. Just likes a very mild load.

Thanks for the great info GANDERITE,

I am using plastic boxes that hold 50 rounds as well it works great for this :)

I only have 10 shells left using the Speer, I won't be using it anymore.

Here is a question, how do you know the bullet is 20 thou off the rifling?

I tried checking the bullet tips for rifling marks but having a hard time seeing them.

I am using a Remington 700 SPS Varmint.

Currently I am loading the bullets a hint less than the maximum total lenght for a 223 cartridge.

Thanks

There is a good chance the bullets you are using are not long enough to reach the rifling in your 700 SPS. Also do not lube the inside of the neck when seating bullets (if I am reading your post correctly).
 
ah, in my speer book and also in my Lee reloading guides they all say to lube the inside of the neck a tiny bit (same with the videos on the Lee website)

is there a reason not to lube them?

I am up for trying anything as long as it is safe! :)

What I am reading in your first post is that you are lubing the inside of the neck before seating the bullet? A little lube on the inside of the case is OK when resizing but not when bullet seating.
