Thread: 338 Edge on a Factory Striker

    Default 338 Edge on a Factory Striker

    Its been a couple months coming but it is here. Not sure how many handguns are out there in the 338 X 300 RUM (338 Edge)but I have mine now. This project actually started some time ago when the muscle brake was tested on the 338 X 300WSM and then the 338 Win Mag. Finding them pleasant to shoot after making some minor adjustments I took the plunge.
    I purchased a Striker from afar and had it delivered to Jim at The same day I called Ron at Benchmark barrels and ordered the lightest large shank 3 groove, 19 inch barrel he could safely make.

    I and Lisa are up to it in a huge remodel at the facility. I took a break and was camped at the range at daylight and what is pictured are 3 shot groups only and the first and only 12 bullets down the barrel. The velocity I will not publish at this time because I think they were too high. I will take the other chrony out Friday weather permitting and double check the results. I need to do a trigger job on this beast as the trigger has got to be 7 or 8 pounds. If the PACT registers anywhere near what I got today then I will be one extremely happy guy. I can say that with 93 grains of H4831 which is a top load in the 338 Rum I am at 338 Win Mag rifle velocites with lots of room for more powder.

    Video to follow as Lisa won't have time for several days to get it done. The muscle brake was absolutely amazing! Very pleasant handgun to shoot with no muzzle rise so to speak.
    Top to bottom targets. 1: 93grs H4831 (was used in all data with all bullet) 200 grain Accubond
    2. 225 grain Accubond
    3. 210gr Partition
    4. 225 gr Barnes MRX

    The white dot is 1"

    I am not sure if Jim has published the following data before me or not. His wife is an audiologist and has some very expensive sound measuring equipment. Jim used the 260 Remington rifle as a base test, minus a brake and measured the decibel sound to the shooter at 119. He then took his 7 RUM with muscle brake which holds twice the powder of the 260 Rem and registered a 121. decibel to the shooter reading.

    Default Wow!

    Looks like a interesting combination and certainly sounds like a real handful there EI .

    I have enjoyed my Contenders, but I've not seriously pursued a turn bolt handgun. You mentioned you have a 19 inch barrel; are there special permits for such a long barreled handgun? I was thinking that a handgun must not have more than a 16 1/4 inch barrel. Thanks for sharing.

    No sir!

    If one has a designated handgun there are not minimum or maximum barrel length requirements.

    I normally have only 17" barrels on my hunters. With this larger case capacity I wanted a tad more barrel length assuring that I could get the velocities I wanted.

    I have a friend that has a 22" plus brake barrel on his 338 Lapua handgun.
