The points outlined here, and the issues described, I encountered in my first ELR rifle build in 375 RUM.

I wanted to build the rifle myself, with my limited budget that could not afford a factory ELR rifle like a Victrix or Barrett. I sourced the barrel, action and stock, bought the reamer, and gave the project to a gunsmith.

I was aiming to get to 2 miles with the rifle.

The stock was a hunting rifle configuration, with an adjustable cheek-piece.

The barrel twist was 14, for some reason I had 3000 fps in mind, which was achieved with 247 grain monolithics, but proved inadequate in the wind at ELR ranges.

The action was a Remington that could accomodate a magazine.

At the time, I would have liked to try 338 grain monolithics, there is certainly enough case capacity in a RUM for that, but the twist limited me to 280 grainers. In reality, using 338 grainers would have made very little difference, the 338 grainers BC is marginally higher than the 280 grainers, and both are inadequate for ELR.

There was not enough elevation to get past 2000 meters, it needed an elevation adder, like an Ivey or Era-Tac.

I used a rear squeeze bag, with mediocre results. ELR is better served with a solid rear rest and an adjustable bag rider. If the rifle is heavy, as in the 40 pound heavy range, a squeeze bag is useless - you can't apply enough force to the bag with one hand to steer the rifle.

The most sensible choices I made were the scope and bipod.

The scope is a Vixen Artes with 100 moa elevation. The scope has proven reliable, consistent, and gives a good, clear sight picture at ELR ranges at 20x .

The bipod is a UTG Big Bore Stability. I enjoy the height of it, and the ability to lock the legs down.
