Since I posted that info 5 years ago I have switched to VV N570 for magnums. Its very stable for temperature. About .1 fps per degree compared to 1 fps per degree for RL 33. But honestly i havent built a 28 nosler in a year for customers. Everyone is wanting my 30-28 nosler or 300 norma improved. They have 75% less throat erosion and are way easier to keep in tune. With the 30-28 you simply run a .306 mandrel through the 28 nosler brass. Stuff 83 gr of h1000 into a 230 berger and it bugholes. Or 86.5 gr of h1000 and a 215 berger and it bugholes also. Both those loads have shot into the .1s moa wise out to 950 yds in my setup. My 230 load is probably the most accurate combo Ive seen. 83.2 gr of h1000 will hold under an inch of vertical at 580 yds. The last two groups I shot had 1/2 inch vertical at 580. 230 berger at 2965 fps. Ive switched to the 230 bergers though in my 30 cal setups since theyre a little more optimally seated in the case for my throat setup. Also the slightly lower velocity compared to the 215 berger is an advantage at closer ranges. The 300 Norma improved starts off where the 30-28 tops out at. The lapua brass for the norma is indestructible. I put 28 WARM firings ona single piece of brass and the primer pocket feels almost brand new. Very wide powder/velocity nodes in this cartridge. Not much recoil either with my self timing 5 port brake. I can watch the vapor trail and spot hits no problem in a 10 lb w optics 300 norma improved or 30-28 nosler. The 30 cal magnums have been so popular Ive just started keeping complete rifles instock ready to ship.
My next barrel will be a 30-28 from you without a doubt. In the mean time I've got another 300-400 rounds left in my 28. I couldn't get my hands on any nv570 so I've got enough RL33 to last the life of the barrel.
I have a question.... if my 28 shoots 3050 at 80 degree sea level. Will my gun be shooting roughly 3000~ at 15-30 degrees in November? Also if the node is 3040-3055 should I increase powder charge before hunt to stay in that node?
