I have loaded Sierra 100 gr. Semi-pointed soft points # 1550 bullets that I have to about 2700 fps.
Have not shot anything with them yet but penetration tests in jugs of water are more than a 30-30 with 170 gr bullets at 75 yards. I am sure they are going to work as well as the 30-30. I hope to see this fall.
I have also compared the 243, 100gr. SP to the 117gr. RN from the 257 Roberts at 2700fps. and I know they work.
I have sectioned many bullets and I have seen that heavy Sierra bullets have thicker tapered jackets that other bullets.
I have only just picked up some Nosler Partitions and will be trying them next year.
I have used lots of Sierra 85gr HPBT's and they are tough bullets as well. And to make them better slow them down a bit.
At 2900 to 3000 fps will still expand at 250 yds.
That's my thoughts.
