Hot loads
- Thread starter Mark C

Every barrel and chamber is different. That's why you should work up to a load. I have got to much pressure before max on some loads and have worked up past max loads without pressure signs on others. Be safe and slowly work up your loads.
Some of my loads are realitvely hot but none are one shot and done on the brass like I've seen some guys at our matches. On my 243 I'm running 105s close to 3,300fps. I tried backing the load down for mid-range but it just didn't shoot as well. Bottom line I'll run the load where it needs to be to shoot the best.

Well ...I guess you know your limits then.....That's a good thing.

This^^^ Start low, work up and let the gun tell you where max is. And just because it might be safe with 48+ grains doesn't mean it will be accurate there...
That sir is very correct!!
Varget can be tricky. I've seen pressure signs with loads below max in the manuals and well under the expected velocities. Safe reloading requires carefully watching for pressure signs and stopping when you see them.
Very responsible and true replies above. Shooting fixtures and test guns come in all shapes and sizes. If you have several reloading manuals check to see what each used in their testing. I enjoy looking at the old Speer manuals to see what they used for testing...some good data to start looking for loads in old military guns....
A buddy let me borrow a throating reamer earlier this year. A little deeper throat in the chamber allows bullet to stick out of the case further. Less bullet in the case = more room for powder and/or less constriction for pressure to build. In my load, I just wanted less bullet in the case...I did not go up in powder. Some folks do lengthen the throat to eek the bullet out a little more to add powder capacity....it may work in their gun/situation, but not in ALL guns, and certainly not in ALL situations. Working up the load is the ONLY safe way to get to correct charge for your gun.

May i ask, or shall presume that your asking this because you have a .308 that your wanting to load the SIE 2155 or 2156 bullets for. Is this rifle a "Palma" rifle or a run of the mill standard hunting rifle? Do you know what kind of chamber it has? Maybe a 95 or 2011 palma chamber. Maybe it is a Browning BLR with an oversized chamber and neck to facilitate better feeding? I can honestly say, that the best loads i have seen with the SIE "Palma" bullets has been around 46.5 to 47.00 of Varget, Winchester or Lapua brass.. (this is before the new style of Lapua "Palma" .308 brass).
