CC,

I agree with that, my 7 mag is the same way. I always shoot a spoiler before my "group" testing of new loads. Elkoholic307 is saying that during load development that 5 shot groups tell him a lot more than 3 shot groups. I'm interested in what he's learning from the additional shots.

bigshot, I just checked my Barnes Number 4 Reloading manual (the most recent). It has data for the 180 TSX and 180 MRX listing the max charge of Retumbo at 93 grains! The max velocities for all powders range from 3089 to 3180. I had a bad experience once (only a stuck/ruptured case thankfully) from pushing a 270 WSM too fast. be careful.
Sorry it took a bit for me to reply, I worked five hours overtime today. I obtained the info from the longrange shooting forum and I thought it was listed in my Nosler Book as a max load. My rifle and brass do not show any pressure signs, just alot of recoil. I always check the books before I try a new load, and noticed it was way above max in my Barnes book, so I worked up to that load and it turned out to be the most accurate.

Ok,
Just made it home and checked my Nosler book #6, I was wrong, it list 99 grains of Retumbo as max with a 180 grain bullet and at a listed velocity of 3,343 fps. Wow, BB must be right, and just way too much pressure.

I prefer the 200 grain Nosler Accubond load anyway, so I'm going to stick with that load. Thanks for the heads up guys.

bigshot,

The Barnes bullets are solid copper. Accubonds have a gilding metal jacket. Barnes also have relief grooves. These bearing surfaces are very different, so the data used for one is not good for the other.

Those group sizes are downright spectacular in a sporter. Keep that gun.

I shoot a remington 700 Sendero in 300 RUM and did a lot of load testing before I found my load. It is 93 grains of retumbo pushing a 208 hornady
A max 3100 fps. It groups amazing with my best group being .514'' at 300 with 3 shots. Many people will say its not a hunting bullet but they are wrong.
Between my cousin and I we have killed 4 deer and 3 elk in the last 2 years with them, and no animal made it farther than 50 yards. And the bc is .648 so
the long range performance is awesome, we shoot em out to 1400 yards.

Wow, what type of primers do you use.

Hey WA Hunter, how did the Hornady Amax perform on game. You mentioned, you and your cousin took lots of game with them. Do they expand like Nosler Ballistic tips or do they have controlled expansion. Not too familier with that bullet. Did you get an exit on the deer and elk? I found a good deal on some of them bullets and thinking about buying them.
