Quote: The original 450/400 was 2050 fps I think with a 400 gr. The original .404 was about 2150 fps or there abouts. Seemed acceptable back in the day. Now the .404 reaches 2300 to 2400 fps. All these cartridges have very similar performance. From 2100 to 2400 fps and even up to 2600 fps I believe with 400 gr bullets. Myself 2350 fps plus or minus is fine. What speeds are people getting with 450 gr projectiles, .416 or .423? |
