Do Moly Coated Bullets Shoot Any Different?

On Cabelas? I was looking at that too. I do know they have Hornady 55gr FMJ-BT in stock right now as well.

From what I understand they will coat your bore and supposedly improve your accuracy. I've used them for 100 rounds in a 75 grain Hornady A-Max. I didn't find any additional accuracy out of the rifles I tried them in. Further I heard that they can damage your bore if left uncleaned for an extended period of time. I'm not certain of any of this though.

For me the shoot just about the same. The theory behind them is coating your bore in moly and gaining more predictable (AND SOME PEOPLE CLAIM) higher velocities. If youre going to use them and switch back to jacketed youll need to clean your bore if youre worried about accuracy. Sometimes the moly in the grooves will cause groups to open up if switching back to jacketed. Also moly is a pian in the you know what to clean out of a barrel
Thanks for your help. I went ahead and picked up a couple of boxes of the Moly coated 55gr V-Max at Cabelas this afternoon. They also had a pretty decent selection of powders in stock. I managed to get 2 lbs of H322 and there was at least 6 more lbs of it on the shelf when I left. I also picked up 2 boxes of 50gr V-Max without the Moly coating.

I shoot moly coated bullets often. Using the same powder charge as a standard jacketed bullet,I have always showed the moly bullets to be slower than the jacketed bullets.
I was surprised by the chrono numbers the first time I shot them,but in every caliber I have shot moly's out of,they are a lot slower than the same jacketed bullet powered by the same powder charge. The chrono doesn't lie!
I've never found cleaning moly residue any different than regular cleaning of a barrel.The patches just look dirtier from the moly/carbon build up at first.

Yep, that's common knowledge amongst us reloaders. I used to moly all my rifle bullets. Got tired of it and only shoot plain jacketed bullets now. Did ruin a barrel, because I thought I had all the moly out of the barrel when I put the rifle up for the season. Bore was totally rusted out.
So Moly absorbs moisture? I always clean my guns within 24 hours of returning from the rangee, but during deer season I try to keep the bore fouled unless it rains or snows and then l'll run a patch with oil down the barrel and wipe down all metal parts with an oiled rag.
Do you happen to know if those Nosler CT's are Moly coated? Thanks for the info.
Moly coated bullets will run slower with the same charge because they are slicker and that reduces pressure. We can however, increase the charge and not only match but run them faster than uncoated at the identical max pressure, but not identical charge weight.
Benchrest shooters, including myself at the time, gave them a long look, but the vast majority gave up on them.

Yup, as it travels down the barrel, the friction causes a major heat wave which then morphs the bullet into a screaming ectoplazmic orb...
Oh wait, no that was my dream, ... gotta talk to the doc about them meds.
Ah, well , maybe a little, see Walkalong's answer..

To me the benefits are not great enough to complicate matters. I like 'em nekkid!
I'm with you, but these are trying times so I guess it won't hurt to give them a try. Hopefully I'll locate some of the regular 55 gr. V-Max before I get around to reloading these. If they don't do as well in my to bolt action rifles I can always use them for plinking in my Mini-14. I've got about 6 different online stores that are supposed to notify me if they get any of the regular ones in stock.
This is completely unscientific but I shoot moly bullets exclusively through one of my ARs and consider them to be extremely accurate. The bullets in question are 77gr SMKs that come moly coated from Sierra. I have a few thousand on hand so I'm not going to switch now. I seem to remember a distinguished shooter telling me that a number of Army shooting teams use the moly 77gr SMK bullet for service rifle, maybe even the AMU. I use 25.0gr of Varget or 24.8gr of 4895 with the 77gr moly SMK and both will produce sub 0.5 moa 5-shot groups off a bipod at 100 yards so I wouldn't consider moly to be detrimental in any way. The 5-shot groups shown below are typical of my DPMS 24" heavy fluted stainless barrel. Notice that I had good results with 24.7gr, 25.0gr and 25.3gr of Varget but the "standard" 77gr SMK load that shoots great in just about any 1:7 or 1:8 barrel is 24.0gr of Varget. Maybe as Walkalong mentioned the moly results in slightly lower pressure at the same charge weight and perhaps that's why my DPMS shoots great at +1.3gr. I don't think I can get much if any more powder in the case so that's as far as I got.

I was at a br shoot yrs ago and the weather was misty drizzly. IOW a lot humidity in the air. When the guys shooting molly went to brush their bores they found an ooey gooey mess that they couldn't hardly brush out. It was a mess to say the least. So I never considered shooting molly after that.
