Should i be worried that maybe using max load for deepcurl HP may not translate well to solid brass of the same weight? Any info is appreciated.
Worried? Ab-so-frackin-lutely!!!!
Is your rifle going to blow up with these loads? I doubt it. Is there a possibility of damage? Quite possible. Are they likely to malfunction? Very likely, but not an absolute.
One of the things that determines the pressure of a given load is the bullet. NOT just the weight, but what it is made of, and the bearing surface. In other words, the resistance it has to going down the bore. More resistance = higher pressure.
A bullet made of brass, (lighter than lead & copper) MUST be longer at the same weight. Longer means more of the bullet is in contact with the barrel (longer bearing surface to be engraved by the rifling). This means higher pressures, for a given powder charge.
Using a max charge for bullet A shooting bullet B could put you into dangerously high pressures, right out of the gate.
THAT Is why we ALWAYS say start low, and work up, in small steps.
Every gun & ammo combination is a unique individual. They tend to fall in patterns, but exceptions DO exist. What is max for one rifle and bullet may not be for your rifle and bullet, or it may be well over max for your combination. The ONLY way to know that is careful testing working up loads from BELOW published maximums!
If you don't already have one, get a bullet puller. You WILL need it, at some point.
You only have two "safe" options. Pull down the loads you made up, OR put them aside, and, using the SAME COMPONENTS work up your load from below, until you reach the load you made up before, IF YOU DO!
If you run into pressure signs before reaching the load level you made up when you were "in a hurry" (and you might), then your option is simple, you must pull down the "too hot ammo".
You spent a lot of money on your gun, kind of stupid to risk damage, I think. Even dumber to risk injury over a few dollars worth of reloading components.
Done right, all the components of the pulled down ammo are re-useable.
