Yes it sure can. With the proper lube, hardness a gc you can push lead at 3000fps without leading provided the fit is correct.
I shoot non gas check bullets upto 1650fps without leading issues. Again proper fit is key, for me its the largest diameter i can fit in a case and still chamber the round without any resistance if the barrel is not the best shape. My 71\84 mauser likes lead .004 over slug size as do a few of my older rifles, but my newer rifles with good bores shoot 0.002" over slug size very well and no leading issues
for my non gas check loads I use this formula to get a idea for what the lead hardness should be
"Simply multiply the alloy BHN by 1,422. or divide the pressure by 1,422
Example: Alloy BHN of 12 multiplied by 1422 = 17,064. An alloy of 12 BHN should be used with a load that develops a "minimum" of 17,000 psi."
