Loaded my 30-30 cartridges 7.5 gr of Bullseye, bullets 168 gr. CB's from Bullet barn. primers were large rifle. fed 210
Shot in my savage 340..
Well at 25 yds they are fun to shoot , accurate to an inch.
Question is after firing the primers are slightly protruding.. is this a problem ??
want to try trailboss drove all the way to chilliwack last wknd, could buy anythin at that show but no trailboss!!!
 
I will be honest, I've never heard of anybody using Bullseye in a .30/30 before. It's the fastest powder out there, commonly used for handguns.

I dug through a stack of reloading manuals and the only reference to that combination was the #38 Lyman manual from the 50s, which lists 3.5 gr of Bullseye under an 87 grain cast bullet and 2 to 3 gr of Bullseye under a 45 gr round ball.

Where did you come by that load?

Well I had some!! I cant remember where I got the load I just used 168gr bullets and looked at loads of other powders and tried it.. I figured around 1100fps as the bullets are not gas checked.
I did ask some other reloaders and they thought it was safe also,, please dont think I am recomending this I only used it myself..just the primers bugs me..not new to reloading but am to the 30-30
 
Primer backing out suggests either there's not enough pressure in the load, you are sizing your cases too much, or you have too much headspace.
If its a chamber issue, or sizing issue, it can lead to case head seperation. Neck-sizing only, can mitigate this.

My first thought would be the charge. Try a powder more suitable.

I would agree.
 
Somewhere there is info on a thing called the universal load. It involves light Bullseye in just about any calibre if I recall.

The primer backs out, then normally the high pressure pushes the case back onto (reseating) the primer. Yours didnt get seated due to low pressure. This is OK.

You need to always make sure the bullet left the muzzle before firing the next shot with really light loads. If it hits a target and you know fine, if not you need to check the bore.
 
Thanks . I might check the headspace. Also, might try large pistol primers. Trailboss must be pretty popular hard to find
 
Its a low pressure issue, and very common on light cast bullet loads. When a cartridge is fired the fireing pin drives it forward in the chamber. The building pressure first unseats the primer and blows it back against the boltface, then the entire case is driven back reseating the primer.

In the case of light loads the cartridge doesn't develope enough pressure to overcome the friction of the chamber walls and the primer is left sticking out.

With bottle-neck rimless cartridges the practice can permanently shorten the case from shoulder to base, causeing excessive headspace and problems of case head separation if the cases are later used with full power loads. This doesn't apply to your rimmed 30-30 cases though.
 
I would put my money on a low pressure issue. Are the cases sooty?

A little.!!

I got a handfull of kids 13-17 all wanna shoot .I got lots of rifles and a few 30-30's they all want to graduate from .22's so 1. safety 2. cost 3.recoil 4. easy on my rifles!!! Once these kids get bored I'll work up to reduced loads with maybe H4895 or somethin.
Lots of fun good on grouse and excuse to buy more rifles!!
 
I get rounded primers with Trail Boss too, they don't look flat and flush like a normal load. Anything with that little pressure will not flatten the primer out, or stretch the case back against the bolt face.
 
You have received good information above about the light load, and slightly excessive headspace. Nothing to worry about.
There is also nothing wrong with the load of Bullseye you are using. That is the correct range of powder weight with fast burning powders, to include Bullseye, 700-x, Red Dot and the like, to propel a cast bullet. At that weight you don't need to be paranoid about sticking a cast bullet; your velocity should be around 1200 fps. Sticking is an issue down about 2-3 grain when you are shooting the cast bullets down around 600 fps.
You don't need trailboss. I have shot thousands of rounds using fast powders. You simply need to set up your reloading to ensure no double charges. Some routines that I use with rifle cases (because you cannot see down into them easily as you can with pistol cases) are:
- All cases mouth down, charge the case and put it in another block.
- Charge all cases in the block and then run a small dowel down into the cases. After the first couple you will know exactly the height and you will feel the dowel touch the powder.
You are on the right track. Enjoy your loads.
