I loaded IMR 4895,32.5 grains,one grain below listed minimum for the 53 tsx in the barnes manual.
it is very mild,but accurate in our rifle,and a 62 gr .224 diameter bullet at 3200-3300 is plenty for deer.
when we shoot up the box or two we loaded last year ,we will work up a load,for now,this load seems to work fine.
the reason there is so little data,most 22-250 wont handle this length of bullet,either in twist rate,or magazine length.
it was either barnes or one of the powder makers,will provide load data if you call and ask.
