Re: Moly or Not?
Moly lowers pressure, flattens the pressure curve, and moves the peak pressure a couple of inches down the bore.
Slightly higher velocity is possible with moly but the important benefit, IMO, is increased round count before cleaning and then a much simpler and faster cleaning. I clean with 1 oiled patch followed by 3 dry patches. I am currently using BreakFree CLP but have used CRC 5-56 and know others who use any light oil with equal results.
I moly my own bullets with SF grade moly from Rose Mill Co as price was slightly better than Dow for 1 lbs. I tumble only bullets and moly powder (no steel shot) in large pill bottles. No dedicated tumbler bowl is required and clouds of moly are not produced when using the pill bottles. 10 oz soda bottles do just as well as pill bottles and availablilty is better. I do not wax.
IMO it is better to start with a bore that is either properly broken in so does not show signficant copper fouling after 15-20 shots with non-moly bullets, or with bore hand lapped to the extent that the barrel maker agrees is suitable for moly with the first rounds.
Clean the bore and prep with moly paste or cream sold for the pupose. Avoid molying the chamber. I used a cartridge case with the head drilled and a short length of 3/8" pvc with my .300WSM but you can use a comercial bore guide if you do not mind moly coating it's interior as well as your bore.
Rapid fire is the crutch of an incompetent marksman. ONE SHOT, ONE KILL
