Ok like was mentioned, why not...not sure if mine qualify being modified, but here are a couple anyway.
I don't have much in the fancy dept. or short barreled dept either. I like velocity, range, and heavy for caliber bullets. Hard to get the most of them all from a short barrel. The accuracy ain't too shabby either.
First up my old 25-06. It started life in a standard BDL fashion, but after around 10yrs of hard hunting I replaced the warped stock with a Fajen laminate. Sometime around 5yrs ago I presented it to the daughter, and now her oldest is working hard to pry it from her hands, so here is "our" rifle,
The grandson and I did a little shooting back around Memorial weekend, and after he got done burning up some old mixed loads, I cleaned her out and fired one fouler and two for group at 250 yards. I do not have to shoot any more than this to know it's on, with the 18 - 25 gusty wind we had that day I didn't even bother adjusting the scope. The load is a 110gr AB over a goodly amount of RL-22. It shoots the 115gr Partition almost identical.
Then I guess there is my 25-06 AI which started life as a standard 700 ADL in 30-06. It sports a Broughton 28" 5C 1-9", HS Precision stock, Holland .250" Lug, Callahan firing pin assembly, and Jewell Trigger set to 1.5#, and Weaver 3.5x15 Tactical optics. It runs a 125gr Wildcat RBBT ULD out at 3350fps, and they groups pretty close to the one above at 300yds. This little shoat was earholed from 275yds.
Then theres the standard ol Sendero in 7mm RM. It sports a Burris Signature 6.5x24, the load used for this deer shoots averages around 1" at 300yds using moly coated Hornady 162gr BTSP pushed along at 3150fps over a load of RL-19. It dumped this nice buck on his nose at 285 yards.
Then just for kicks, here's my .270 Allen Mag, which tarted life as a standard 700 ADL in 7mm RM. It sports a 30" 1-8" Lilja, Holland .250" Lug, Jewell trigger set to 1.5#, H-S Precision Stock, Nightforce 5.5x22x50. She don't do bad out at 500yds,
She's a bit rough on the feral hogs at ranges closer than around 400yds, with shoulder shots usually resulting in prairie dog like explosions from the 169.5 or 195gr RBBT ULD Wildcats running 3250'ish fps respectively.
