Best for the Ar-15

[mrblue]

Looking for a mold that will work well in the mags/feeding and cambering. Whats everyones suggestions for a mold? Thanks(I tired to do a search and it's not working for me)

I use a NOE that is a clone of RCBS 22-055, sadly he is out of stock.

ALSO, I am eagerly awaiting this one come to fruition.
it's a long thread, but a good read, lots of people have put in valuable input, this should be "THE" AR boolit mold.

those molds are coming along, the sprue plates are being cut and are almost done.

Yup I've been trying to get some imput. I want the NOE one, but he's been out for a while, and to wait for that custom one would be nice too. Just wish we could find things instock to buy

I use the rcbs 2 cavity version and it makes boolits just fine.
it has been making enough for three ar's and three bolt guns for about 4 years now.

I'm excited about the mihec 75gr 22nato in the current group buys. It's gonna be a long wait...

Yeah the heavy weight 75gr one has me reaal interested. I think it'll be much easier to get nicer results out of a slower heavier bullet than a light & fast one:

*It can go slower for the same amount of energy, important if you want to use it in competitions where PF matters
*Probably cycle easier at lower velocities too
*I figure it'll burn better with slower powders
*Slower velocity = don't need to use as hard an alloy since it won't go as fast
*Better ballistic coeffient means the lower velocity won't matter as much

And a heavier bullet will be slightly more forgiving towards tiny weight differences as well, though I will probably still sort them by weight like I do my current 62gr ones.

This is for jacketed bullets, but it shows why heavy bullets are nice if you want to shoot far:

Ya'll might want to consider the trade off of having all that nose out front; with the GC at the base of the case neck will it fit the magazine? With all that nose out front (bore rider that it is) will it be accurate in the 7 & 9" twist barrels at the velocities you guys are thinking? Consider the problems the CM gives in the 7.8" twist of the 6.5 Swede..........at any velocity over the reported 1800 fps.......and usually less.......

I have the 62 gr NATO and percieve the nose to be about as long as practical. I have very good success (around 3 - 4 moa with 20 shot groups at 100 yards) with a 69 gr 225462 at 2100 fps in my 9" twist AR and at 1700 fps in my 7" twist AR. It does best at 2300 fps out of my 12" twist AR.

I'm not saying the 75 gr Nato won't work as I'm probably not even going to get a mould. I am saying that it may be a little too heavy for the kind of wishful thinking I see posted here. Remains to be seen, good luck.

I dunno, I looked at the 65gr profile and the 75gr that was published and I put them next to each other. It seems the 75 and 65 have the same nose length and profile. The 75gr bullet seems to achieve the extra 10 grains via the use of another lube groove, so in relation to it's overall length the 75gr has less nose proportionally speaking. I also noticed the nose on my 65gr bullets where smaller than the driving bands so I don't know if they engage them? I am not familiar at all with bore riders mind you.

The 75gr one will have the gas check sticking out of the neck when loaded to 2.260" OAL but no lead should be exposed.
