With their 286 Big Game data, they are beating my load by 75 fps with 4 grains less powder. My barrel is a 12-twist 22 1/2" Pac Nor. Safe to say they are using historic, and low, pressure levels.
Edited: I hope you are using a chronograph? Might not be getting what you think you are getting for velocity sans it.

Anybody who seriously concerns themselves with the adequacy of a Big 7mm for anything we hunt here short of brown bear, is a dufus. They are mostly making shidt up. Crunch! Nite-nite!

I do have a chrono and will put it to use and report back.
All of them do something better than the 30-06, but none of them do everything as well.

Been waiting on some measuring components. I like to measure to CBTO vs COAL. My only ammo I have shot out of my Sauer 100 are the S&B 285s. re loading the once fired brass. 285s are 2.756 to ogive, the Accubonds are 2.600 I trimmed my case to book specs. 2.431, I wish I would have left it at max of 2.441 after getting my chamber gauge, I guess can leave little more meat on the case for next time. loaded up with big game for next weekend. Wondering if it's ok to have the bullet stick out as much as it does past the cannelure.

took out some loads this morning. I have to say, I am not impressed or maybe embarrassed a little? there were lots of variations and not consistent. velocity or some loads were off the paper and some were perfect. I'll post a pic the best one and it's the max load of 63.5 of big game from ramshot. no where near the velocity of their published data. I was really hoping to be over 2500. Rifle sauer 100 xt, Monarch 2.5-10x42 in talleys. I will look into the 62 and 63.5 gr loads and play with seating depth. 60gr 2368-2372 fps 60.5 2302-2393 61 2380-2398 61.5 2402-2433 62 2433-2478 good group 62.5 2424-2446 63 2433-2469 63.5 2455-2473 best group 64 2455-2482 [img] https://i.imgur.com/gkYkgG5.jpg?1[/img]

Big game is going to shoot a ton better when you get above those computer generated loads western lists
Also what primer ?

Dre,
What jmd025 posted--which is essentially what I posted before in response to your questions You're still not anywhere near the best operating pressure for Big Game, and that still means a SAFE operating pressure. That's indicated by the velocities you're getting.
One of the problems involved with century+ rounds is throat length varies considerably, which affects pressure (and hence velocity) considerably.

Big game isn’t designed nor will it perform worth a flip at conservative , old school 9.3x62 pressure levels . They are the way they are for safety in old guns . Big game needs modern pressures . That’s why it performs better with heavier projectiles as well . In modern guns , you can get there , but the load isn’t in a book (unless you bought Gun Gack )
Once upon a time I tried some light loads with Hybrid 100v in another cartridge ... same results , flat sucked at low pressures .

Also what primer ? Yes, Sir, as in John's observations. As far as I know, I was the first person to try Ramshot powders in the 9.3x62, about 6 years ago when I purchased my CZ 550 in that chambering. I worked up to 65 grains of Big Game with 286's and got superb accuracy (as in 3 shots touching or nearly so) in the 23.6 barrel, at right around 2500 fps. This is with the Nosler Partiion or Barnes TSX. I had it pressure-tested and it got around 60,000 psi. Charlie Sisk and I have since used this basic load in a number of rifles with uniformly excellent results..... Ted

Thanks everyone for the replies. I also have hunter laying around for my 270 and tac for my 223. Which one should I try? Also when I got upto 64 grains I’m not sure how much more capacity I had left....looked pretty full.. I didn’t want to compress the load. So should I go to 65, 66 with BG? Or just invest in varget or rl15?

Well my rebore by JES in my Remington 03A3 shoots super! Loaded some Woodleigde bullets 250 gr. bullets is grouping nicely and it's a 4 groove, so don't know why pabucktail says he only does 3 groove in 9.3 ? One hole works for me! Tried some Big Game was ok and shooting Varget with the 250's doing great, but it does have a thump! CCI 250 primers just about to get it dialed in and going to shoot some hogs next week in OK to see how it does. Those Woodleidge bullets ain't cheap! Taking it to Romania this fall to shoot Roe buck, fallow and boars!

Dre how do you like the sauer 100 xt? Really thinking about ordering one myself to just use the 250's with. Will keep shooting 286's with 65 grains of big game in my old mauser with red dot. It flat hammers deer. But not wanting to get a new bolt put on for scope use. So really thinking about the sauer. Your first person I've seen using one , so figured I'd ask how you like it?

I still use JB's data in a CZ550 like his, still does the exact same things, and still seems to kill whatever I shoot at.

My Sauer 100 9.3x62 is shooting 1/2" @100yds and 2" @400yds. I know it shoots alot better than this old wore out hunting guide can. Good Luck!
