[QUOTE="Blackbears4ever, post: 1993081, member: 115249"] I have Weatherby MK-V in .257 Weatherby magnum. My barrel is a 1:10, 26” and my most accurate & consistent bullet has been the Barnes 100gr TTSX. Retumbo 3550fps which is equal to Weatherby ammo velocity. I can get over 3600fps but groups open up. Reliable 5/8”- 1.00” groups. The heavier bullets I tested didn’t shoot as consistently. Maybe they require a 1:9 or 1:8 twist. I only hunt game with Barnes bullets. Recovered 2 100gr TTSX bullets buried 12 inches in the dirt after a pass through on Black Bears and they weighed 97-99 grains. Have fun working up loads. [/QUOTE]
