Hi all! Just getting into LRH - I just want to confirm what the latest fastest and most accurate long range cartridges are for the following bullet diameters (given 26-28" barrel length...)- please let me know!! From several books and internet sources, I have come up with a short list below. The cartridges can be wildcats, factory or proprietary as long as they have achieved a high degree of respect and credibility against their peer cartridges for velocity and accuracy. 1. .257 - is it the .257 Scramjet or the .257 STW (hot tomale)? 2. .284 - is it the 7mm RUM or 7.21 Firebird, other? 3. .308 - is it the 300 RUM, 300 Pegassus, 30-378WM, 30-338 Lapua mag (wolf), 7.82 Warbird, other? This should be fun Thanks.
