My 28 does 3060 with 195s. I sold my Rum but it used to get 3202 with 180 hybrid. Coincidently, I talked to a guy the other day who claims his rum shoots the 195s at 3375 with 28" broughton barrel, 102 grains of H50BMG powder. I can't see how, but he claims he can prove it. I think I may ask him to prove it. Just wont stand too close while he is shooting.

"Sure I can!!! 1 shot per brass, some of them have the primer fall out after I shoot for some strange reason, and I carry around a wood hammer handle to open the bolt after I shoot, it's pretty stiff, I have been meaning to oil my gun, it's dirty as heck!! But that is ok, with the performance I'm getting I only need one shot anyway!!!!!"

Lol. Stand clear when he "proves it"

Put it in a lead sled, strap it down, and use a 20ft string.

My 28 ran them in the 3050 range with good brass life and not hot roddin it, my 7mm rum AI runs them at 3200 on a 30 inch krieger I have ran it up to 3260 but brass wont live past 3 loads there in the summer, When I was testing loads for that rifle it would loosin the primer pocket open before it would get a tight bolt or ejector swipe. I ran it up to 99 grains of 872 and hit 3350 but the primer was not held in any more lol. I look at the primer flow into the firing pin hole with that rifle but at 3200 it keeps good brass life.I have just formed up a batch of Bertram brass for it and I am going to test it and see if I cant get a tad more out of it because it hits a really good node at 3260

I run my 7RUM at high 31's. Have to send my bolt to gretan for a bolt bushing. I'm pretty sure I smoked the firing pin hole. Lost a lot of primers at 32+
Hope it stops losing primers when I get the bolt back. It has a good node right over 32. 28" krieger

When I built mine I did a few things to try to keep pressure down, the AI and a stepped throat, and a .062 firing pin on a one piece bolt(not for pressure but to be tougher in pressure). I really like the 872 powder in that rifle. I bought 16 pounds of 33 but I ended up running the 872. I am hoping the bertram brass has a tougher pocket

If you get the barrel throated long for the 195's in a 28 then performance will be pretty similar with everything else being the same. Both can push it 3100+ safely. 28 can be loaded to that speed in a standard long action (will need longer than standard magazine for a repeater, will need to load around 3.73" to maximize capacity and performance). RUM will need a magnum length action.
