From what I've read and understand, the win action is just as good, if not better then the Rem. I'm not a gunsmith and dont know the technicality behind it, but I'm sure someone can explain. I thought it had somethign to do with the bottom of the action? But not to sure. However, any good gunsmith, like a few on this site should be able to work on Wins with no problems. I think the Rem LA might be a little longer then the Win LA which would work a little better with longer VLD type bullets to reach the lands and be able to use as a repeater, but once again, not 100% positive on that.
BTW- I had a bonestock (other then trigger work) winchester model 70 in 25-06 that I guarantee would give a custom rifle
a run for its money in the accuracy department. I'd bet the rifle on it! I've got a group in the 0's with it and many in the .2-.3 range. It shot every bullet I wanted to better then .75", and more around .5". However on a sidenote, I also had a win mdl 70 in 7 STW that wouldn't group for chit no matter what I did. Bed/free float/trigger job and trying about a zillion different bullet/powder/primer/OAL combos. IT just wouldn't do better then about 1.5".
I"ve converted all my rifles to Rems and have had no problems with every Rem I"ve fired. I've gotten great accuracy .25-.75 with nothing more then a trigger job and feeding them what they like.
I wont buy another Savage as my dad and I both bought .270 WSM's and they both were JUNK. They wouldn't do better then a 1.5" group at 100 yards. Not to mention on my dads rifle the screws to mount the scope base were crooked from the factory, then when he got it back, we stripped them trying to install the base. They both had trigger work done and I tried about 5 differnt bullets, 5 different powders, 3 different primers, and about 5 different OAL's, nothing seemed to make a difference. Kinda left a bad taste in my mouth for Savage.
