Yeah the doctor blamed my shoulder on swinging sledge hammers at work for the last decade. Probably a bit of both. I couldn't even shoot skeet this year. Target loads in an 8 lb Citori were too much. It has come a long way in the last few months though.

I hate to sound like a hippie, but I'll risk it.

Sauna. It's freaking amazing. Find a massage therapist with an IR sauna and do a few sessions. You'll thank me.

Very lovely & rare .450M Steyr Big Bore.

Currently load my .450M BLR & .450M Ruger No.1-S with Buffalo Bore ammo 500gr Barnes Buster chronographs ~1675 fps mv. https://i.imgur.com/fu9TTGp.jpg / https://i.imgur.com/ynwjBnY.jpg / https://i.imgur.com/Qipe85J.jpg

Mild factory loads held to 43,500 psi for use in .450M Marlin & Winchester lever rifles. In strong actions I'm pretty sure .450M 500gr @ ~2000 fps mv is safely possible.

Thanks. It's one of my never sell rifles.
I'm also a huge fan of the browning BLR stainless takedown I'm 450M. I love the 1-lever takedown feature which makes it very easy to pack out. Only "downside" is the 7lb weight and straight stock design make it less pleasant to shoot hot ammo at the range. I got a half dozen boxes of Buffalo bore 430gr hardcast back when wanstalls was clearing them out for 66$ (again I want to say 2019) and they definitely get your attention. With the so-so trigger I feel I can't shoot more than a few rounds or I'd develop a flinch. I had mine cerakoted burnt bronze by blackbox customs and am very pleased with their work. Perfect for the wet coast. I had them do a Sako 85 375 h&h Kodiak (in a brown bear stock) and finnlight in 243 (perfect for island blacktail).

My 450 Rigby with reduced loads 500gr campro semi spitzer (100gr IMR 4831) let you know that you have touched it off.
Full power 550gr round nose loads lift your front foot off the ground.
Too me that is a big bore.
If it doesn't wake you up like that then its not a big bore, lol
 
Firing CamPro 405gr with my .458 Lott @ ~2400 fps mv seems some didn't make it to the 100m target board disintegrating in flight? Maybe not surprising copper plating only 8 thousands of an inch.

Gotta say, shot a lot of full house .450 Rigby, never had my foot leave the ground. They’re tied for my least favourite recoil impulse, but they’re no 4 bore. ;)

Had a 9.3x74 R in a Ruger No.1, regrettably sold that many moons ago. More of a medium bore, and reasonably comparable to the .375HH. Stylistically I was never a huge fan of the design of quarter rib and banded front sight, but a real sweet rifle.

Picked up a custom left handed .458 Lott built on a CZ550 Magnum action, thankfully it came with some brass and dies! Looking forward to seeing how it shoots.. and if I really dislike the recoil I'll consider re-barreling to a .375 or .300 HH.

lol the ammos in 375hh or 300hh will float in the big magazine ... you can still load down the 458 lott ...
 
Just thinking it makes sense to redefine the categories into 0.1 in increments, as the really big bore cartridges are much less common with modern tech.:

.20-.308 Small bore
.308 - .400 Medium Bore
.400 up - Big Bore

I'm good with considering all >0.40's as big bores but that doesn't appear to be the consensus here.
