21.1 Grains Green Dot / Figure 8 / Versalite / WAA12 / Fed 209A, 55lbs wad pressure. 1.125 oz. Shot. This is one of the closest duplicating loads I can find. This is a great load and easy on the hulls so you get more reloads out of them.

Git-ER-done has a good replacement load. That is close to what I reload for HDCP. STS/Nitro hull TGT 12 wad Rem primer w/18 grains of tightgroup a little goes a long way!!

The ORIGINAL nitro 27's contained 21.5 grain of Clays International, all Rem. components, primers and figure 8 wads I was fortunate enough to be among the prototype testers, the second generation nitro 27's have 18.5 grains of Tight group powder and Rem. primers and TGT-12 wads, as the Tight Group powder is very dense, all factory ammo will read 30 to 35 ft. per second faster over our chronos than the OEM testing which reads the pellet mass not the lead pellet, if you reload and want to duplicate, keep this in mind. incinerate em!

This is living in my archives:<blockquote><I>"To duplicate the Nitro 27 shell use the following recipe:<ul><li>Remington hull<li>18.0 grains of Hodgdon's TiteGroup powder<li>Remington TGT-12 wad<li>1 1/8 oz of shot<li>Remington 209 primer</UL>

I believe the pressure is 10,200psi and measured 1235 FPS through a Ohler chono out of a 30" barrel with an IM choke. My deviation was 10fps out of 10 shells. This same shell chono's the same out of a 34" barrel."</I></blockquote>

There was no mention of a pressure value.

I use Green Dot powder and it is too bulky for the TGT12 wad but works fine with a Figure 8 wad or equivalent.

Unknown1 has it.

18 grains of Titegroup with the listed components.

bigben is right with the history (although Remington no longer buys the powder from Hodgdon, what they use is essentially identical to Titegroup.)

But I think his 18.5 with Titegroup gives you 1255 fps, and 18 grains gives you 1235 according to Hodgdon's data tables.

Rob, Downrange has a great clone of the TGT. Or you can buy the real thing. This is a great load for Handicap.
