.270 WSM is not a round you send a lot of lead down range with. It is a hunting cartride. 2 shots in .75" is a good hunting load. Keep it for hunting, and build a dedicated long range shooting rig. .300 WSM won't be much better unless you go with a heavier barrel. If you still want to rechamber, try Phoenix Custom Rifles. They just completed a laser beam .300 RUM for me. And did a 6.5 SLR earlier this year.

30° shoulder, longer neck, same design as the 6x47 Lapua. Shoulder starts at same place as .243 Win. So very, very slightly less case capacity but better & more efficient shoulder/neck design for increased inherent accuracy. Should be the same load info as a .243 Win for the most part. I have a 6.5 SLR and LOVE it.

So I was dying to get a few rounds down the barrel to season it and at least get an idea, so I swapped my SWFA 5-20x50 HD fro my AR onto the RUM. I just loaded 15 sight in rounds @ 85.5gr, of H1000, and also a bunch from 85.5 to 92.0 grains if H1000 for a ladder test later on. Shot a total of 12 rounds today. I took the chrono out just to get an idea of what it was doing from a 27.5" barrel. Sight in loads are as follows: Remington once fired brass trimmed to 2.835" CCI 250 Mag primers 85.5 grains H1000 210 Berger HVLD 3.685" COAL (just barely fits in mag) 3.077" to ogive 2957fps average ES=22fps (2948-2970 over 12 shots) SD=6.11fps Conditions were as follows: 75°F Wind 1-3mph fluctuating Baro 28.22 Humidity was somewhere around 65% according to Weather Center.com Rifle weighs in at 13#. With the Badger Thruster brake, it recoils just barely more than my 10.5# .25-06 Ackley shooting 115 Bergers @ 3400fps. (I hear a lot of people stating their .300s w. brake shoot like a .243). Must be a feather weight .243 shooting some hot loads. Or a 18# .300. Anyway, onto the results. A few of the chrono readings first. First group of 3 shots from the rifle after bore sighting only. I am pointing to the first round on a new, clean, oiled bore. Adjusted reticle right 3 clicks, up 18 clicks (1.8MIL or about 6" @ 100 yards) Shots 4 through 6. Shots 7 through 9. Adjusted down 1 click, left 1 click (.1MIL each) Shots 10-12. I quit there. Not much more I can do other than try to speed things up a bit. This is with absolutely no load development. It is with the first powder charge and seating depth I tried. Just seated to max mag length and let them fly. To say I am happy is an understatement. I think I am going to leave it alone for Taylor's elk hunt in a month, as recoil is very manageable, and with the altitude and projected temps, it should retain 1500 ft/lbs out to 1000 yards or so, and 1000 ft/lbs out to 1350 yards. I will take it out and stretch it's legs after deer season to see how it shoots at distance and true velocity an verify drops however. Should make for an elk hammer once I get it sped up a bit too. It will go with us as an alternate backup for deer though. Huge thanks to Phoenix Custom Rifles for putting together a laser beam on the cheap. I was giving my wife a hard time, since I just bought her a new Camaro last week, saying I get to go buy a new scope now. What can she say?

Not exactly. Base to shoulder, body taper, base diameter, yes. .270 has a longer overall case length (.050"), slightly longer length to start of neck (.050" due to necking down the parent case further to .277" to start), and longer neck for bullet purchase. Forming it to Ackley will increase the base to shoulder length by about .100" over a .30-06 Ackley case and you will gain a minute amount of less body taper too. Every little bit of case capacity helps in the hot rod race. A win by a nose is still a win. Plus, longer neck might mean very slightly inherent accuracy. Again, even .001" in accuracy is still a win. It will be cool to see how this turns out.

I have an idea for you....

Exactly!

Don't crimp. UNLESS you have a bullet with a factory cannelure (the indented ring around the bullet for the crimp to hold into). Even then, I never do. Neck tension is plenty to hold a bullet securely in the case mouth, and improper crimping does more harm than good.

Plus Varget is much more temp stable. RL powders are notorious for big velocity swings when temps change.

I kind of liked the green stock with the stainless in the "white" look, but a little bling for my intended hunting use.

Great to hear you got it back.

Awesome job!

For the metal, I always use a stripper and degrease. Then hit with brake cleaner and finally wipe with water. It has always adhered perfectly. Even on polished stainless. Never had a chipping issue except around the crown where I get solvents on it. For the stock, I used 120 grit lightly, then 220 grit sand paper. I didn't want it too smooth, so the paint will adhere well.

Aerovoe for the metal. Rustoleum, Krylon, and will use a bit of model airplane paint for the stock.

You cannot compare the binos to the accesories. The binos are the best made, by anyone. Other companies make a better adapter however. Swaro is not in business to sell adapters. They are there to sell optics. They should stick to that.

Absolutely love this thread! Awesome job to the huntress on a fantastic buck, to Dad for getting here out, and to Adam, Big Browns, for helping out!

You tell your gf to fetch the napalm out of the utv, instead she brings you an F...ing hockey stick? Time to reassess this relationship. Heck with the Gopro, its only going to bring nightmares. I killed a rattler out back and cut his head off. A dude from CWT was coming over to borrow a horse trailer, it was dark out we both had flashlights. so I coiled the dead snake up and placed under the trailer tongue to scare him. Dude hooks up the trailer, steps on it several times but never once saw it till I pointed it out. That is plain mean! I like it!

Congrats on a great mule deer. Going to be some tasty eating!

DAMMIT!! I am sitting on site in my work truck, and a dang plastic wrapper blew by my open door and scared the crap out of me just now while I was watching that video!!!

Great memories, and lessons learned. Sounds like a successful hunt to me. Even with an unused tag.

I appreciate it. If I get desperate, I might have to take a drive.

My add would look more like this...... Bed. Rustic, hand carved, w. shed deer antlers. Wife does not approve. Wife for sale, $400. Trades for hunting dog will be accepted. Located in Tucson, will deliver within 1000 miles at no extra cost.

Huge thanks to Charlie, 5GuysHunting, for selling me a 3/4+ # of H1000 to get started. I got 10 sighters of a light charge @ 85.5gr. loaded, and a ladder test set from 85.5gr. to 93gr. in .5 grain increments. I still have plenty for getting some loads together after my ladder test & group testing. Got my seating depth for mag length right now, and still have plenty of case capacity, even at 93gr. if needed. Base of a 210 HVLD is still just barely below the body to shoulder junction at mag length plus a little wiggle room. Berger book states 84.0 to 88.2gr. of H1000, Hodgdon book states 85.0 to 90.0gr. for max. Another source has multiple people shooting 92gr. and one guy shooting 95gr., but he states it is a hot load in his gun. Seems high to me too. I hope to get out and do a ladder test in 3 weeks. I plan on sighting it in and getting some foulers down the barrel this weekend. I won't finish the paint on the stock before the elk hunt at the end of Nov., because I need to get a load worked up first.

Great story. Congrats on the deer. Congrats on the shooting. Good to see people giving thanks to God & the AZGFD.

Awesome story, awesome deer, awesome huntress and values. Great job on raising her correctly.

Sound like too hot of a load if you are getting sticky bolt lift. Be very careful. Any other signs of overpressure, like flattened or catered primers, case head swipes, ejector marks, brass flow, etc.? The reloads are the minimum powder load, not sure on factory but buddies gun doesn't have issues with the factory loads. Books give you a reference. Only your gun can tell you what it likes. Depending on brass make and content, I have had way over pressure from the same loads I always run when it is hot outside, and when using Federal brass or military surplus brass for various chamberings. The more brass content, the less case capacity. Meaning less room in the case=more pressure when fired. There are other possible issues that can lead to over pressure. Bullets jammed or touching the lands of the bore, high ambient temps, different powder charge or different brand or lots of powder themselves. Tighter chamber cut, not all "SAAMI" chambers are cut exactly alike, either from a factory or a good gunsmith. I weigh each case and discard any that are out of spec. I like a 2 grain max difference in brass content for my rifles myself. Something like 124 to 126 grains for each case, or 171 to 173 grains, etc. Mixing different brands is bad. So if you load some Winchester at 160 grains of brass content, Remington at 170 grains of brass content, and Federal at 185 grains of brass content, and size them all with an FL die, they all have the same outside case diameter, but thicker walls equals less case space inside the brass. Bad for velocity, accuracy, and pressure. I have found up to 55 grains of brass content difference in .25-06 cases between 7 brands/head stamps. Winchester, WW Super, Remington, Federal, Frontier, Hornady, Nosler. Nickel plated cases make a difference too. Depending on how you weigh each charge, you can easily get discrepancies in charge weight. A powder throw can miss a charge weight by .2-.4 grains. My Hornady electronic charger/scale is off sometimes up to .2 grains for a 43.0 targeted charge weight. I individually weigh each charge on my RCBS 5-0-5 beam scale for this reason. If you set an auto charger for a certain charge weight (say 50.0 grains), they are good to read within ".1" grain. But they also have an error factor of .2 grains easily. Meaning you can be at the low end of your charge and be at 49.75 grains, or be at the high end and be at 50.25 grains. A .4-5 grain swing is bad for accuracy, and if your max pressure that your gun likes is at the 49.8, but you are getting some at 50.2, that might be enough to cause overpressure. Go up in charge weights, the error factor goes up too. Add a slight overcharge of up to .4 grains, a case that has more brass content/less capacity than previous cases (whether from brand changes or just batch or machining changes), a powder that is temp sensitive (and you did load development in a cool month), higher ambient temps, a bullet that is touching the lands, and a tight chamber, and you have a recipe for a hot load very easily. You might not even know about it. Just spit balling here.
