My 6-284 XP-100 was built primarily to shoot the 115 DTAC. MV's currently in 2700+ range. Of course will consider Wildcat bullets for LR hunting, but am working on 1k+ PD's and potentially 1 mile (will be shooting at 5000 ft. + Elevation).
Where to start concerning SP's[img]/ubbthreads/images/graemlins/grin.gif[/img]
Remington no longer makes XP-100's, but you can find them used still [img]/ubbthreads/images/graemlins/smile.gif[/img]
I own XP's and other types of specialty handguns that could be described in terms of LR Shooting/Hunting in these cartridges:
8T 6mm-284, two 8T 6.5-284's, 9T 284 Win, 7T 7mmWSM (still waiting on it), 10T 7.82 Patriot and a soon to be built a 1-7 twist 7mm Dakota.
Several of my SP's will group in the .1's-.3's @ 100 and .75 inches to 1 inch @ 300 yards, 1.5 inches @ 600 yards and 5 shot groups @ 1k (During IBS match for record score) 9-12 inch range. For those who have done the 1k game you will understand when you have four shots in the 6 inch range or better and one that moves you out several inches [img]/ubbthreads/images/graemlins/frown.gif[/img]
Most of mine are the old center-grip XP's (single-shot action) that have a H-S Precision stock ( I do have a one rear-grip McMillan BR stock though.
One way to think of them performance wise (rule of thumb) is if you have a 284 Win. case you will get 7mm-08 rifle performance, or just a tad more. If you have 7.82 Patriot you will get hot 30-06 rifle performance or light 300 WM.
When you have a stiff action and short stiff barrels with the same added machine work that accuracy smith's do to BR rifles you can do to a bolt pistol action. You can shoot sub 10 MOA groups at 1k with the 3-12 Burris LER scope. One can also have a 36x Leupold converted by Wally Siebert into a 20x LER handgun scope. Another thing that i have done for some time is use high mag. rifle scopes on my SP's. I get a full field of view and then pull back. Brakes are a big help here, especially with the big boys.
Well, maybe this will wet your appetite. There is a forum that is dedicated to handguns and primarily to specialty handguns Specialty Pistols
