    For you gents shooting the big 7mms, How fast have you been able to drive these bullets before they start coming apart?

    3,200 ft/sec has been no problem in my Hart barrel with 11 twist. Bullets do a job on whitetails!

    Thanks VH, thats a start. The 160/162 class will be as light as I go, I'm leaning towards a 9 twist as I will mostly be looking at 180 gr Bergers, 190 gr JLKs and 200 gr Wildcats.

    Anybody gone over 3200 with the Amax?

    Chris...
    I have a multitude of different big 7's, and have run the present style 162 A-Max out if most of them at over 3200 with no issues. These bullets never seemed to shoot well at the hyper velocity. I never settled on it as I went to the heavies in all of them.

    What barrel lenght and twist would you guys recommend for the 162gr bullets.
    I have a bone stock rem. 700 adl right now and was wondering if the stock barrel would improve with a heavier bullet. Been shooting 150gr bullets right now, but after reading all the great info on the 162gr I was thinking of trying it out. The stock barrel is 24", i've been told that a longer barrel could help. If I go with a premium barrel I would want to get one to utilize the 162's.

    Everything I have is 28" or longer.
    26"-28" will work well with a 9 tw.

    My 7RM with 24" barrel shoots the 162's really well. I can't remember the twist, but it is the Remington stock twist rate. Best 5 shot group is just over 5/8" at 200yds !
