That's interesting, thank you. A COL of 2.650 will not fit the magazine, but I have tried a couple of other cases (Remington) and now it looks as though 24gr N140 will go in with slight crunching and give COL of 2.280". A good reason for checking case capacities In the first place! I'm not comfortable with compressed loads though so will abandon this idea which was to use the longer, heavier bullets for 600 yard shooting (in an AR-style rifle, hence the need to use the magazine).Originally Posted by bullbarrel
I use this load for shooting on the local range to 600 yards. I use 24gr of N140 and col of 2.650 in my Tikka T3. I don't think its compressed.
Have you measured your rifle's ideal COL? Could be it will give you the room for those extra grains.
Or just load a test round (not primer or powder) to 2.650 and see if it fits in the mag and chamber. If so, try to see how many more grains you can get in
Remember to measure it again when you take it out of the rifle to make sure the bullet hasn't been pushed in a bit.
