Trailboss in the 38-55

**brstevns** · 10-09-2015, 05:43 PM

Would like to try Trailboss in a 38-55 Win, with the Lee 255gr and a Lyman 285 gr bullet. Need help.

Bill,

Hodgdon's website shows Trailboss loads for that caliber.

I have been there, but it does not show loads for the heavier bullet. Searching the web shows some are using 10, gr ? I would think about 7 would be enough. even with the 285gr lyman bullet.

I am also seeing people posting about loading up to 11.0g of Trailboss in a 38-55, - but all the published data I find says max is 7.0g

There's a formula from the hodgdon website for trail boss in all cartridges. Double check to make sure, but I believe its to figure out where your bullet will be seated. Fill the case to the base of the bullet (not compressed) then weigh the charge. Take 70% of the weight of the full case charge and that is your starting load. So if your full case was 10gn then your starting load would be 7gn.

BP	Bronze Point	IMR	Improved Military Rifle	PTD	Pointed
BR	Bench Rest	M	Magnum	RN	Round Nose
BT	Boat Tail	PL	Power-Lokt	SP	Soft Point
C	Compressed Charge	PR	Primer	SPCL	Soft Point "Core-Lokt"
HP	Hollow Point	PSPCL	Pointed Soft Point "Core Lokt"	C.O.L.	Cartridge Overall Length
PSP	Pointed Soft Point	Spz	Spitzer Point	SBT	Spitzer Boat Tail
LRN	Lead Round Nose	LWC	Lead Wad Cutter	LSWC	Lead Semi Wad Cutter
GC	Gas Check
