You have a bunch of good powders. r15 h335 imr4064. Somewhere around 2900 fps.
The Dunning-Kruger effect is alive and well.
There might be some useful information from Hodgdon. They don't list the bullet you are using but they do list a bunch of powders with two other 125 grain bullets.

According to QuickLOAD
For a 24 inch barrel with O.A.L. of 2.800 and trim length of 2.005
Here is some comparative data for RL-15, IMR4064 and H4895.
The first two are temperature sensitive so I provided data for 40 deg. F and 70 deg. F.
H4895 is temperature insensitive (less than 8 fps change from 0 to 125 deg F)
The 30 degree difference in temperature should be able to cover most of the US during the afternoon hours.
The changes are practically linear so you can adapt the fps for temperatures that are colder or warmer.
All of these loads are well under the 62,000 psi SAAMI Pmax for a .308 Winchester cartridge.
Hornady 125 gr HP #30192
RL-15 40 deg. F. --------------- RL-15 70 deg. F.
46 gr = 2,764 fps 36,520 psi -- 2,820 fps, 38,742 psi
48 gr = 2,888 fps 41,551 psi -- 2,944 fps, 44,024 psi
50 gr = 3,013 fps 47,242 psi -- 3,069 fps, 50,062 psi
IMR4064 40 deg. F. ------------ IMR4064 70 deg F.
44 gr = 2,688 fps, 35,581 psi -- 2,739 fps, 37569 psi
46 gr = 2,810 fps, 40,502 psi -- 2,862 fps, 42,728 psi
48 gr = 2,933 fps, 46,061 psi -- 2,984 fps, 48,605 psi
H4895 -
44 gr = 2,880 fps, 38,656 psi
46 gr = 2,932 fps, 43,912 psi
48 gr = 3,056 fps, 49,892 psi
Thank's CF Junkie, this helps a lot
If you want something really pleasant to shoot and economical on powder, Hodgdon youth load data for a 125gr using H4895 has a huge velocity window.
For the .308 and H4895 they use a formula that lists up to a 60% reduction of a Hodgdon maximum listed charge as safe. ( for H4895 only)
I use 38gr H4895 and 125SSTs for the grandkids neices and nephews as a hunting load. More than the minimum using the reduced load formula, but plenty to get the job done on a deer. One of my nephews took a really nice buck last January on his first ever hunt with one of these loads. The kids will also shoot up 50 rounds of .308 at the range and ask for more.
I've gotten to where I enjoy shooting reduced H4895 and light bullet loads myself because of the reduction in noise, muzzle blast, recoil and powder consumption.
Just thought I'd put it out there in case you're interested.
