Get the non-moly
Not like it really matters, just doesnt hurt to shoot naked bullets.

Re: Molycoated vs Non-molycoated
Until you fully understand how to take care of a barrel that only gets moly coated bullets stick with naked bullets, also your gonna need a 1/7 twist barrel to stabilize 77s out of a 223/556 weapon.

77gr IS pushing it.. But my mate shoots them ok thru his 1/8 twist
Ar-15 rig.
I would try a lighter weight first until you get to grips with it.

fokai_zach,
The 80 grain Sierras stabilized in my out of the box .223 Savage with its nine twist. Same for the 75 grain A-Max. They gave about the same accuracy as the 65 JLKs wich was about 1 1/2" at 300 yards. Neither was as accurate as the 55 Noslers in that particular rifle.

Re: Molycoated vs Non-molycoated
sorry failed to mention this is shooing out of an spr 1:7 righthand twist.

a search for moly coat, moly coating, etc. provides alot of input, both factual and opinionated.

True, which is also accompanied with lower muzzle velocities, ----
So, with moly bullets, you add more powder to regain the MV and pressure curve; so you pay more for the bullets, more for powder, and maybe clean less.

Re: Molycoated vs Non-molycoated
Sometimes by adding more powder to get the same pressures. You will add velocity to your load.

Re: Molycoated vs Non-molycoated
I would put my vote in for non-moly coated.<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: MitchAlsup</div><div class="ubbcode-body"><div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: Rarebreed93</div><div class="ubbcode-body">According to JBM, Molly gives you less internal pressures. </div></div>

Although there are vastly varying opinions that I have heard regarding Moly coated bullets, my experience with Moly coated bullets is that they run slower than non-Moly coated. I prefer more muzzle velocity so I would say go with non-Moly coated.

Re: Molycoated vs Non-molycoated
By running moly bullet you do decrease the pressure, but adding more powder You add pressure therefore you gain velocity. It takes less friction with the same pressure. If you don't add more powder, you will lose velocity.
I think you will find by running moly. You will gain speed. I use moly on my match guns. The everyday shooters I don't.
I ask a similar question about a 8 months ago. I got answers both ways. So I tried it. In my results showed some benefits. Best way to know, is to try it.

Re: Molycoated vs Non-molycoated
It takes many shots [some say 50] of moly bullets to get a bore coated with moly.
This can be sped up to one shot with Lyman Moly Bore Cream
The advantage of moly bullets is that it may take twice as many to Copper foul a bore.
The disadvantage is that one must get moly in the bore under the Copper, not over it.
Most shooters I have seen cannot maintain a disciplined moly regime.
Maybe most shooters on this forum can, but not shooters I see at the range.
