TL310-225-RN-CE3 TACO Bullet for the 300 Blk
The Taco bullet was designed by Full Lead Taco to be used as an “easy to cast, coat,
load, and shoot bullet for the 300 blk. The tumble lube version and the nose configuration
were proposed by GearNasher. The tumble Lube grooves do make it a little harder to cast
in comparison to the “Slick sided” version. But should be a small trade off if they help as
proposed – will see.

Used a 5 cavity mould, washed in hot soapy water and pre-heated it.
Pot temperature was 700F. Lightly smocked it with a propane lighter and ran it up to
frosty bullets, about 485F. Backed it down to just a mat grey finish, 390F to 420F and
cast with it. Did have to work with it a little to get the grooves to fill out.

Bullets dropped from mould at .3106”, base band did run .0003” to .0004” bigger on
my mould with our wheel weight alloy. Powder coated with (2) coats of Harbor Fright
Red (400F for 20min) .3128” and sized to .3102 with our bushing push through size
die .310. Did use some Hornady Unique Case Lube to lube them with. Works wonders!

Now to get back in to the reloading room and get them loaded.
Looking forward to doing a side by side with the HTC310-225-RN-CE4
Will post as we go.

Al’s bullets are always the most shiny!  Mine never get as shiny as his, ha ha!

Any update on how these bullets performed. I am looking for something in this weight range to use in my 10.5′ build. My only concern is that my Barrel is a Faxon Firearms 5R 1/8 twist and I have heard from some that its not fast enough to stabilize something this heavy.  Any thoughts?

I just received the HTC version that drops at .310 into water with my current alloy. After PC it is .312 and definitely needs some Hornady One-Shot spray lube to be able to size it back down to .309, plus it increased length by 0.007″ (lead has to go somewhere) – I think this is what the TL version makes a littler easier. Like the banding in Barnes solids to reduce engraving pressure, the TL design would help there too.
I’ll probably purchase the next size larger sizing die to make this a little easier in a couple steps, use a thicker bench top and a longer arm on my RockChucker press.
When I’m done experimenting with the Grendel mold(s) I’ll work on this a bit more.

Using a light crimp from a Lee collet die and 10.5 ~ 11.0 of Accurate 1680 loaded to 2.218″ COAL, I can stay sub-sonic out of my 16″ barrel.
The sad part is that while I can achieve single digit Sd using S&B primers that’s not where the accuracy is. It’s probable that my powder coating is not as uniform as it could be.
