ABLE;
Many are reluctant to offer advice or loading data lest the asker misuses that data and tries to hold the askee/responder responsible for the misuse of said information.
Having said that; I have a load I've been using since the late '70s straight from the old DuPont IMR loading pamphlet/guide.
I load and shoot this recipe to this day in my two 336s. It IS HOT by today's data in all the manuals but it is the most accurate load ever shot in these two Marlins AND in my H&R .30-30 barrel with 150 gr SSTs.
Speer/Sierra; Take your pick...Both equally accurate. IMR 4895 37.0gr/ WW brass/ WLR primer (Started using originally Win. 8-1/2-120 primers and went with newer WLR Standard primer when they hit the shelves). Still have a few old 8-1/2s laying around. If 5 shots covered completely by a nickel at 100 yds. doesn't fit your need, then; [It Ain't Gonna Get Did].
Stats are:
H-2423; L-2387; AVG.-2406. ES-36/SD-18.(150 SIERRA)
H-2444; L-2402; AVG.-2423. ES-42/SD-29.(150 SPEER)
These above loads are from DuPont/IMR GUIDE [1971] and initially loaded in Nov.'75; Still loading same today. Chronoed loads in Oct '91 @ 12' w/OEHLER 35-P (these particular rounds originally loaded in Oct.80)

H-2561; L-2521; AVG.-2545. ES-40/SD-20. (130 SPEER HP/37.8 IMR 4895/Fed/200; Seated deep enough to crimp the case mouth over the shank/shoulder junction compresses the powder enough to keep the bullet in place w/o too-short OAL. 3/8" C-C 5 shots. Chronoed AUG.'03.

As said previously, these loads are Hot by today's data but are still okay in MY Marlins. I make no assumptions as to their safe operation in your rifle(s). You asked for 150gr load info, and here are some. Perhaps the 130gr loads will be accurate in your guns also. I've tried various powder/wgt./bullet combos, and IMR 4895 has been the most accurate by far in MY 336s, followed by H322.
Can't speak for any other combo in any other rifle.... Each one is an entity unto its own.
Good luck;
WILL
