Recoil should be less. Unless you run into a big big blackie, that 200gr I'd have confidence in.

For reference, that spring bear in my avatar went a bit over 525#. Used a 50 Alaskan on him thou.

With my 16" Bushmaster upper that I sold off a while back, I worked up stout loads for the 275 TSX and decently hot loads for the 200 XPB. Could have gone a little higher with the 200 XPB but I knew I wouldn't be shooting past 50yds, and it had great accuracy at that load. There is a good bit of difference in recoil between the 2. I took my 275 TSX load on my bear hunt in Maine a few years back, and the results were incredible!

I would agree with AL, the 200 XPB should be fine, as long as you're not going after a really big black bear. I would crank up the loads though, it has a higher expansion velocity, and poor B.C.

Also look into a limbsaver or similar pad for the rifle. I have one on my 450B AR, and it makes a difference.

Well we worked up our 275TSX load to 2165fps with great accuracy and the kid said recoil was less than factory Hornady 250's. Kid and I loaded 40 more and crimped them beautifully until we went to put the scale away and noticed we loaded them on the wrong graduation so all of them were 5 grains short charged...DOH!! Pulled one and confirmed we in fact short charged them all. Had the kid pull them all down. The bullets have visible crimp marks so I decided re-purpose them for my MZ instead of re-working up with a shorter or longer OAL to avoid the same crimp indentations. I noticed these 2 boxes were slightly smaller diameter at .450 vs the older box I had which measured .451" and you could feel the difference in neck tension when seating the bullet.. Matters not because a few weeks back I picked upa box of Barnes Vortex Factory 250 TTSX's and tested them. They chrono'd 2165fps with an nice 1.2" group off a single bag. After some consideration of my options with reloading the 275's and keeping velocity above 2000fps, I decided to buy 2 more boxes of the 250 TTSX's as they were softer shooting and I would think offer earlier expansion. They also have the same exact POI as the 275's and 250 FTX's at 65 yds where we will be zeroing..

When I got this ammo awhile back I pulled one and it had 36.2gr of what looks identical to H110 at COL of 2.245" The bullet is a boattail base with the relief grooves more northward than the 275TSX's. The Tip is huge and many have compared it to the 250 Rem MZ bullets with grooves added.

Good info and glad you caught that oops! I had a friend who didn’t catch ones on a 10mm and had the coal 0.020” to short and cracked the frame.
