    I am trying to find a good load with the 180g Combined Technology Ballistic Silvertips in my Remington LSS .300 RUM and am having some form of difficulty. This is the only bullet that this rifle is having a hard time shooting good. The best is 1 1/4" and averages are about 1 1/2" for 3 shots at 100 yards. I am using my trusty H-1000 and have went from 94g up to 99g in 1g increments and OAL's from 3.6" to 3.660" all to no avail. I am getting 3390fps from the 99g load though. What would you do first, change the powder or primer or what?? I was thinking of trying RL-25, Retumbo, or IMR-7828. I was leaning towards Retumbo because I think it is temp insensitive and I have heard/read that RL and IMR powders are temp sensitive. I really really want a good 180g BT load for my .300 RUM, it will be my mule deer load.

    The 180 BST shot good with RL25 in my Ultra out at 1000 yards, under MOA at 500 and 1000 anyway. I only shot it a few times (50rds) The load was tested at 92.5gr, 3.66" OAL at 3190-3200 fps at 16 deg F.

    22 MOA to zero at 1000 if I remember right. They shot very well with RL19 in my dad's 300 WSM too. The 180 BT didn't shoot worth a hoot in either of them though. 1-1.5 MOA or so.

    Is there any particular reason that you are tied to a 180 grain bullet?
