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:
Win Large Rifle Primer
140gr TSX TB
22" barrel on a Model 700
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.
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!
