Mike. i am off the lands approx .1 . I do have an inexpensive chrony and need to get back to the range. Just was curious. there seems to be alot of knowlege here. Will do.
Also, I tried the retumbo. didn't find it shot well in my rifle and noticed compressed loads in recipes listed on LRH.
I will chrono the original 51 gr. I will also load some with different seating depth( to the lands)

I'm running the exact same recipe with 52.4 gr, getting 2854 fps out of a 26" tube.

Hmmmmm. Finally got a chance to shoot through the crony. Got a reading of 2936, 2960, 2949. Fyi. This recipe is shooting approx half to 3 quarter inch groups. Needless to say I'm very pleased!

After the reading these other responses something fishy with my feet per second. I'll have to go find anothe chronograph and recheck.

Out of a 24" barrel you should be running about 2875 FPS with 51 gr. of H4831sc. My current loads for both my rifles is 57.5 gr of Retumbo in my 26" Cooper for 2965FPS, and 53gr.of H4831sc in my 24" Savage at 2950FPS. These loads have been chronographed and drop tested at long range. I use Berger hunting VLD's seated .075 off the lands, Lapua brass, Fed 210's with H4831sc, 215's for Retumbo.

I just shot some 140g Nosler Custom Competitions in my 111LRH with 51g H4831sc and a BR2 primer. The average was just shy of 2800fps. The same powder charge with Accubonds and WLR's went in the mid-2800's. The different loads were shot minutes apart.
