Sure the cases cost more than your plain Jane cartridges

My .240 HS Precision SPL also loves the 100 NPT and over MRP, half MOA at 400 yds. In fact the NPT is the best shooting bullet in that gun, and I tried a bunch. I haven't tried RL-26 yet, may need to check it out. Speed may be a bit more; it'll have to be pretty good to beat MRP accuracy. MRP is pretty close to RL-22, some say it's the same powder. So, RL-23 may also be one to try.

.240 cases don't have to cost more. Roll your own using 25-06 brass and a CH4D belt forming die.

W/W on L, Wby on R, can't tell the difference. Neck is fully formed after firing. Performance is the same, W/W primer pockets are said to last longer than Wby/Norma. Brass may be harder.
