A few questions regarding Min. load data as find in various reloading manuals.
Question 1.
Some calibers have multiple loading pressure data depending on the gun as well as if your desiring light or heavy loads.
One caliber is the 45-70. You have low pressure 18k loads for older trapdoor guns, 28k loads for more modern guns, 40k loads for Marlin 1895 type guns, and 50k loads for Ruger #1 type guns.
I do realize for obvious reasons when it comes to heavy loads you wouldn’t want to use a 50k load in a gun that can only handle 18k rounds. Factory or hand loaded!
it is more then obvious you can use 18k and 28k factory ammo in the 40k and 50k rated guns.
I also realize that for each set of data, the max load listed is the one making out each groups pressure rating. Being that of 18k, 28k, 40k and 50k. Depending on what reloading data manual you look at the min load for each group maybe the same, lower or even higher then the lower pressure data. Example... the min load data for 40k load maybe lower, the same or even higher the. The max load data for 28k.
So my question is this.... use 45-70 as our example, and having a marlin 1895, one could use the minimum data listed for 18k, and work our way up to the maximum data listed in 40k till we find one or more loads we like best based on our desires. Heavy load, and light load.
2nd question.... what are the safety issues with going with lighter then published loads for any caliber?
Example... min load for a particular powder and bullet, is say 18grains, what safety issues should one be concerned with, say using 5g 10g or even 15g? OTHER than the possibility for a squib?
I am not indicating any desire with going with a lighter then published load, I am just trying to learn what safety issues one should be concerned about with going with a lighter then published loads?
The nice thing about 45-70 loads is the vast difference in loading options we have. Ranging from bullet size from 220g to well over 500g, with light loads at 18k all the way up to 50k assuming you’re 45-70 can handle such heavy loads. As a result sometimes we desire light less recoil loads, and sometimes we need a heavy knock your butt to the ground loads. All of which the 45-70 is capable of having.
Thank you to everyone who responds with a serious honest reply.
