USMC pistol guide Question

I normally shoot 50 ft gallery at my indoor range. My typical score is mid 250s. I want to improve my shooting, so I want to do the USMC Pistol Guide. 

I have the following question:

1. is L-8, L-9, or L-10 the slow fire or fast fire sizes?
2. Can I just use the equivalent sizes from the B-2 or B-3 targets?
3. For home dry-fire practice, can I scale the B-2 or B-3 targets?

Thanks,
Paul

Not to hijack the OP, but I too have a question about Zins Workbook.  He says in the 2nd drill to use a small practice target.  What exactly does that mean?
Thanks in advance and thanks PaulNYC for your original question.

Workbook link, for those who don't have it.

I think L-8 and L-9 are based on the 25-yard timed/rapid fire target. I don't think it would hurt to use the 50-foot T/R target.

@BaldingEagle:
"TRAINING TARGET SMALL – A PLAIN BLACK CIRCLE THE SAME SIZE AS THE STANDARD 9-RING."

Again, I think this is the 25-yard timed/rapid fire target. I don't think the USMC workbook involves any 50-yard shooting:

"A PRINCIPLE ASSUMPTION IN THIS GUIDE IS THAT THE 25-YARD LINE MUST BE MASTERED BEFORE TIME IS SPENT SHOOTING THE 50-YARD SLOW FIRE."

(ALL CAPS are due to my copypasta directly from the workbook.)

Good on you both for working through the USMC workbook. My standard question when people post in the "Fundamentals" forum is, "What section of the USMC workbook are you stuck on?" It's too much HFW for a lot of people.

Ok, so after reading John's post, I'll be focusing on the t/r target, b3, for my 50 ft practice.

Thanks,
Paul

Thank you

I made some 50ft targets. Follow the link if you want them.

Paul, 

Those would be great at 1 per page.

My intent is to save my arm from the fatigue of bringing the target back to my position.
