Good morning chaps,

I need a load for my 3006 using the 155gr A-max bullet, Norma cases, CCI primers and preferably H4895 powder.

I have looked in the manuals I/ have but no joy I’m afraid. If anyone else has a tikka m690 I would also appreciate some pointers as to overall length.

I am currently setting up the die to the same length as some 150gr Speer softs the previous owner of the rifle loaded for me, is this a reasonable approach?

With thanks,
GH

Don't know if youre already in the know , but Hogdons charts have this, 155 gn Sierra HPBT col, 3.225 start load 46.0 gns H4895 pressure 41,200 CUP, maximum charge 51 gns 45,000 CUP.

Thank you Steve, I did see that load but it as it was for a different bullet I was unsure as what to do with the powder charge.

Can all bullets of the same weight and approximate construction use same data? If only interms of the starting load?

Ta,

Amir,

within reason all bullets with the same weight can be interchanged,

limitations are, as follows,

BT to FB,

Spitzer to RN

Cup and core bullet to any other configuration as A-frame, TSX, Partitions, and surprisingly enough

Accubonds that appear to have a thicker core yielding higher pressures.

Hmm I wonder if any of this makes sence, I know what I am trying to convey here but I am unsure of the clearity of the statements above.

Ohh well, best regards Chris

Hornady does not list this powder for that bullet. But as others have said, some people will interchange data for similar bullets. If you do that, start low and work up slowly and carefully.

I have a tikka and it lets me really seat the bullet long. This doesn't mean your gun will let you do the same but it is possible. You can tell how far out you can seat the bullet IN YOUR GUN BY DOING THE FOLLOWING:
This is how you make a test cartridge to check your possible length. Do it by taking a once fired case and making a "slip fit" so you can slide a bullet into it with friction. I do it by taking the case mouth and pushing it against my reloading bench or the base of my press. You will make the case mouth slightly out of round so a bullet will fit in with light friction. You should be able to move it fairly easily with you fingers but not so loose that it will move by itself. Then "finger seat" the bullet so it hangs out of the case further than you think it will be when chambering. Chamber the bullet and close the bolt and it should slide back into the case when touching the rifling.
Be careful when extracting the bullet and case so it doesn't move when rubbing against the chamber. Take several measurements until you are confident that you have a consistant reading. Once you've make up a bullet/case that does this and you get a feel for things you'll be able to easily do it for other guns.
Sidenotes:
Sometimes a bullet will stick in the rifling and stay there when you withdraw the case.....a couple light taps with a cleaning rod will drop it back out.
Some shooters take a fully sized case and cut slits down the neck for a slip fit...this works also.
I've seen some people say they consider the measurement to be off by about .010"...they say that doing it this way pushes the bullet about .010" into the lands to get it to move....this may have some merit but it will sure get you close to the right number.
If your gun is like mine it is possible you could hang that bullet out as far as 3.360 or so.

Yes, for sure. If not, there would be precious few bullets any of us could load! Book cautions to use exactly the compnents they list are vastly over blown. The single biggest "component" change we could use would be the firearm and none of us are loading for what the book makers used.

OAL is no more a law than the suggested powder charges are. It's just what the book makers used to develop the data they print. We each must find our own "best" OAL just as we find our own best powder charges, by expeimentation!

thanks guys,


All good information. I will post a target when it all clicks!

Amir
