I'll tell you a bit of the story behind my REM 700 LH 338 RUM.
Started out as a 338 Win Mag BDL model with a chopped off stock.
Swapped for a 338 RUM new factory sporter 26" take-off barrel. 40 bucks.
Didn't have the action or bolt face or lugs trued during the rebarrel. Told the smith I wouldn't blame him if it didn't shoot.
I had the Holland QD brake from the Win Mag barrel switched to he RUM barrel. I'd get good brake on there ASAP.
I remodeled the stock into a heavy but nifty configuration. I could spot all shots from close to far myself. That is a very big plus.
Stock was too heavy. There was a discussion here saying "tuperware" stocks were crap. I called BS on that one.
To prove myself I bought a Remington BDL totally tupperware stock, no aluminum whatever. I filled the magazine bottom and rigged it as an ADL as I glued in a follower to make it a single shot and tuck it on the barrelled and weight dropped to a bit over 9 pounds w/Weaver Tactical (old) scope w/burris signature rings and bipod.
The rig is solid less than 1/2 MOA @ 200 yards my zero distance. It shoots well enough to notice the effect of the 1/8th MOA clicks.
First run at a drop chart from JBM with 300 gr Berger Hybrids @ 2760 is spot on, and I mean spot on, elevation wise at the distances tested so far.(560/680/1003/1177)
That's my story and I'm stickin' to it!
