There is no way you will squibb a round that falls within lead load data.
Keep in mind, all else equal, lead bullets will have less pressure and move faster at the same charge than an FMJ. Theoretically, you should have more pressure for cycling, but the bullet will move slower.
You can run plated with a higher charge and jacketed even more due to the bullet maintaining Integrity at higher pressure, and no worries about fouling the barrel, velocities may not be significantly faster though.. The term "gas check" is used to describe when the gases get a head of the bullet when too much pressure blows passed the rifling. At high pressure, lead doest seal as well against the rifling as plated, and plated less than fmj. You are on the low side for FMJ, but that just means it will be a minor load, very soft shooting. Depending on your recoil spring it may Fail to cycle worse case, and accuracy may be bad, or good.. never know till you try.
You are supposed to run plated bullets with lead data. So that would be a starting charge if it were me.
