Anybody used 62gr. fmjbt from bulletheads? I read somewhere to use speer data ? This would be for an ar with 20" 1:8 barrel. Any info would be great , Thanks

speer manual lists a 62gr bullet. is bullethead the brand name of the bullet?

I would not suggest using unknown products of any kind that you don't have data on if you are not well versed in reading pressure signs. You don't really know what the makeup of the bullet would be, it could have harder allows, or thicker jactets, both of which could increase pressures.

Look at several reloading manuals for data on 62gr bullets in the powder of your choice. Choose the mildest load and work up from there, you will be fine with some common sense.

There are bullets from a website called bulletheads.com. They don't offer any data or bullet specs.

You might send them a message and ask for data .

I'd personally avoid anyplace that uses the complete misnomer "bulletheads" just on principle. If such a sin doesn't set your teeth on edge, just begin with the mildest Start loads you can find for bullets of similar weight, jacket type, and bearing length.

Way back in the old days I would look in my Lyman manual for the right caliber then to right bullet weight and there it was.

Did some searching . On Colorado ar shooters site there was alot of talk about price but no data . One guy said they shot great . On their site he is down to only 55gr. Did find his email address and sent one off, we'll see what happens .

Got a reply for bulletheads . Not helpful at all! His reply was cannot supply data at this time.
