As usual it looks as if I'm gonna learn the hard way.
I switched from a heavily modified REM ADL stock that was designed as a compromise between a long range rig and a carry gun. It's a 338 RUM shooting 300 SMKs. However, it favored LRH a bit more than walk & stalk.
The tupperware stock is an REM Magnum that is hollow in the but. Thus when you hit the gong you get a Doink------Dong. Unsettling.
I can confirm that its tough to get things to stick to the thing. Only took two days to overcome that one.
Secondly the fore arm is far from stiff. However its about like the B&C classic that I ordered for my 270 AM. It was not stiff enough to my liking so I heavily modified it and she's plenty solid. It was pretty much like building a house around a trailer house. But she works fine.
With the Rum and the Rem plastic stock, after all of the work of reshaping, converting from right hand to lefty, the darn thing only gained me 0.8 LBS over the heavily JB'd, devcon'd ADL.and the ADL was much stiffer.
I fired a shot to see what it was going to be like. Big roar, as usual, not much of a kick (Holland QD brake) but she reared like a horse.
The angle of the comb was a bit the wrong way and the newly sanded primer'd come seemed to grip the ol' cheek a bit. I've since remedied that condition.
Before I break out the airbrush and stencils I'll shoot a group or to validate the accuracy of the previous stock has been maintained.
