| My 243 does really well with 70gr SBKs and 46.5gr of IMR-4350 with an OAL of 2.72". It's a warm load so work up.

| One of my .243's most accurate loads is the 75 sierra in front of a max load of imr 4350. I wouldn't think there would be much difference between the 75 and a 70. Good velocity also.
velocity is like a new car, always losing value.
BC is like diamonds, holding value forever.

| IMR-4350 is one of the better powders for this round with any bullet weight. |

I disagree: It works fine with 80 or 85 grain bullets and under, but higher velocities and a more favoarable (ie. near 100%) loading densities can be obtained with slower powders using 90 to 105 grain bullets. Still, 4350 is not a bad powder with the heavier bullets, it just lags 50 or 75 fps behind some others. |

| In the two 243's I've loaded for, H-4350 has worked well with 85 gr and heavier bullets. With 75's I've found Varget gave better accuracy.

| With the lighter bullets I'm having great success with Varget. Good luck.

| Point of information: The moderator referred to H4350. To my knowledge, load recipes for Hodgden 4350 are not interchangeable with IMR 4350. |
