I'm shooting sierra and hornady 250gr OTM bullets from a .338 RUM. My local range that I use 90% of the time only goes out to 500yrds and I'm wondering if I'm wasting my time expecting to see a benefit at that range. 2nd question. Will uniforming the meplets increase the ability of the bullet to expand at long range? The SMK has a pretty small meplet and by trimming them they do open up a little more. Any thoughts would be nice. I'm expecting shots on deer or antelope no further than 850yrds.
