I recently purchased a browning x-bolt in 25-06 with a 1:10 twist. I don't have any reloading equipment so I bought a box of hsm ammo with 115 gr berger vld bullets and a box of nosler ammo with 100 gr nosler partition bullets. I went to the range to shoot and I was not impressed with the above ammo. The hsm and the nosler gave me a 36" group at 50 yards. At first I thought it was the scope, I checked the scope for tightness and all was good. I decided to buy a box of hornady superformance with 117 grain sst and federal fusion with 120 grain. both of these shot 1/2" groups at 100 yards. What would the problem be with the hsm and the nosler ammo? Is the twist rate not fast enough for these bullets or what . What would be recommended for ammo and bullet selection with lighter bullets for use on deer size game?
