Kilibreaux: Hits it on the head: 275-700 grain out of the 4" comped or not are not bad at all, because much of the powder is in the fireball at the muzzle. As you start moving up in length , you burn ( use) more powder and therefore generate more recoil. When you get to 7.5,8 3/8 velocity, power and recoil move up. Note: The 600, 700 grain bullets do not stabilize much past 35 yds out of the 4", they do work well from 6 1/2 up to 18". The most PAINFUL gun is a Magnum research 7.5 BFR with 600/700 grain, very accurate but the grip works too well and you torque your elbow, ( caused 2 cases of tendinitis in 3 minutes ), the BFR is a dream at 500grs and under. I will prob replace my 6 1/2 in 500, and get a BFR in 45-70 in 7.5, very soft shooting with 300 gr Rem factory loads. I would like to try some of the Garret "magnum" loads out of the pistol since they are a blast out of the marlin. Be Safe,
