Gentlemen,

some comments about the mentioned topics :

twist rate and bullet weight:
- Mauser 98, barrel length 58cm, twist 250mm or approx. 1:10"
The rifle shoots very good with 200grs bullets: the Swift A-Frame, the Sierra Matchking and the Nosler Accubond at measured velocities of ca. 820 - 840 m/s

- Mauser 2000, barrel length 65cm, twist 280mm or approx. 1:11"
The rifle shoots very good with the 220grs Sierra SPBT Gameking at a measured velocity of ca. 825 m/s.
The RWS factory load with the 224grs Kegelspitz (cone point bullet)was measured at 835 m/s and shot out of a firing device 5 shots touching at 100 meters (!)

- Remington 700, caliber 8mm Rem. Mag., barrel length 61cm, twist 254mm or 1:10"
shoots very good with 200grs Sierra Matchking and 180grs Barnes TSX (and nothing else)

181grs and 224grs RWS Kegelspitz cone point:
According the the RWS relaoding manual the 181grs bullet was intended for hunting medium sized (german) game like red stag and chamois at longer range. A possible explanation would be that the bullets slowed down after 250 meters and the penetration would be better but bullet mushrooming at this distance would be ensured with a soft bullet.
The 224grs Kegelspitz was intended for shorter distances and heavier game.

I do not use the RWS conepoint bullets in my rifles, I feel that the bonded core or partiton type bullets ae better suited for this cartridge.

best regards
Rolf
