Jack used 62 grains of H-4831 in a Winchester case with the 130gr. Nobler partition. He said 60 gr. Was the max. with the Remington case.

58 to 60 gns of surplus 4831 was considered to be a good zone with 130 gn bullets.
i used a lot of it at 59 gns, giving around 3050 in a brno 600 24"barrel, and just over 3000 in a 22" rem 700.
it was in fact the go to powder for 130 & 150 gn 270 bullets.
modern h4832 (ar2213sc) is equivalent.

I took the chronographer out the other day and here are the results:
.270 Win
Win Large Rifle Primer
58gr H4831
140gr TSX TB
COAL 3.245
22" barrel on a Model 700
2900 fps
No pressure signs and sub 1 MOA! Fast enough too (IMO). Faster than I thought I would get with that barrel and still 2gr below the max recommended by Barnes. Mission accomplished.

I bought some bullets from Rimshot and he is good to trade with!
Greetings all! I've been a hunter for 50 years, but only now planning a trip to Africa. I was fortunate and successfully bid on a couple hunts for plains game in SA later this year and next. Also a rare Native Texas (5th generation) and USMC Vet. Hunt safe y'all!

I am looking for a Safari Express. Was yours made in New Haven or South Carolina? Any other details you can give me? I am very motivated to buy.
