Worked up a load in my 300 WSM. ( 24" bbl ) 66grs Win 760/H414 & the Hornady 165gr BTSP. CCI #200 LR primer, Win brass.Over my chrono 3150 fps. Got my loading info from Nosler . They of course were using a Nosler bullet. Their max load was 66.5grs Win 760. Load worked out great with consistently pleasing accuracy. Just wanted to do some comparison with others out there who might have similar results.

The reason I didn't use the Hornady manual is that I sold my place here & am in the middle of moving. All my loading manuals were packed except for Nosler. Guess I could have looked on line but had limited time to load & shoot. The load work out wonderfully though.

Hornady with 165gr bullet. The max with 414 is 66.9 and their max with 760 69.1. Which makes no sense considering they are the same powder.
Then STFU. The rest of your statement is superflous bullshit with no real bearing on this discussion other than to massage your own ego. Suckin' on my titties like you wanted me.

Will add nosler always been on the conservative side. But if i remember right the partition will show pressure long before a interlock bullet, so that’s probably why.

It is true the partition will create more pressure than a bullet with no partition. Also strange to see such differences in loads listed by Hornady since Win 760 & H-414 are the same powder just with a different label. I assume it could be a difference in lot productions which shows why it is important to work up any load you have if you acquired with a different lot # of the same powder.

MD verified what I was using for years....the Hornady bullets shoot right with the Barnes, they are a good bullet for cheaper practice, etc. I've also used Sierras (Pro Hunters) for that too. Did you trade in that .270 EW for the 300 WSM? ha

3150fps is what I was getting with 65.0grs of 760 and a 165gr Hornady Interbond.I just ran 20 fire lapping bullets down the bore to give me a touch more free bore because my rifle could never shoot anything close to book max without getting pressure signs.After shooting those lapping bullets,the velocity did drop a 100fps on my loads,so I'm thinking now that I'm going to have to bump my loads up a grain or two.I noticed the same thing with the Hornady manual.There loads are kinda all over the place.I too saw the same thing on their H414 and 760 loads.They are the same powder just different lots.If you look at Hodgden,they show the same data http://www.hodgdonreloading.com/data/rifle 760 was the one powder that gave me the best accuracy and velocity in my rifle.Reloader 17 was the highest,but it wasn't as accurate.Reloader 22 was very accurate but the velocity was a bit lower.A lot of powders will work well in the 300WSM,it's kinda like the 30-06,just some may be a lot better than others.I haven't tried Reloader 16 in it yet,but that powder has given me good results in a 30-06 I was loading it in and I think it will be a good powder for the 300WSM.

Are you referring to powder charge or velocity when you refer to book max ? I don’t believe you can speak of them interchangeably. I’ve always used velocity. It will take more or less powder to achieve this velocity depending on your barrel or even the condition of that barrel. 3150 FPS with a 165 on the upper end .

What have you guys shooting the 180 AccuBond found the upper velocity to be with H4350 and RL17 ?

I had to use the help of my chronograph to tell me when I should quit even if I didn't see pressure signs with some powders.Most of the time I'd be getting a tight bolt lift a few grains below reaching book max.There was no way I could load book max loads in my rifle.After fire lapping,I knew the velocity of my loads,the velocity dropped about a 100fps.I was starting to get a little erosion on my throat so it not only cleaned that up a little,it also gave me a little freebore that my rifle never had that was why loads listed in the manuals where always too hot for my rifle.180gr data max loads were about perfect max for my 165gr loads.Now I'm sure the 165gr data will now work for 165gr bullets in my rifle.

I had the same problem with one of my 300WSM rifles. It had a tight chamber and I'd get a stiff bolt lift with 66gr of H4350 and the 165gr hornady interlock. I backed off to 65gr and that was the sweet spot for accuracy as well. What really sucked was I was only running 2,900 fps. with that load. Not that I'm complaining though, as it was very accurate out to over 600 yards. I shot one of my furthest bucks with that rifle and load at a LR'd distance of 600 yards on the nose. Every rifle is its own entity. Some rifles reach their "max" before the books suggest. The only thing you can do is switch to a different powder and see if you can get closer to the stated max velocity without getting obvious pressure signs, such as stiff bolt lift.. I always heard RL17 was made for the 300WSM and you can get excellent accuracy and higher velocity than H4350. I've never used it, but it is definitely on the list of powders to get for the new 300WSM...

I was able to try R17/168 TTSX a few days ago. It worked out especially well as I wanted to try it in temps over 80 deg. ( I had tried R17 in a couple other cartridges that did swell in cold temps) It was 83 deg, and I was only using 3 shot groups ( I always do then I shoot more if a load has promise first) anyhow, this Kimber has a tight chamber too, 64gr was very accurate. easy extraction ( if that means much) went into.40". 65gr, also easy bolt lift, went into a nice, rounded .75". I will chrono them later. Anyhow, R17 proved ( to me at least) every bit as good as H4350 for the temp issue. I'm very pleased, to say the least! I'm settling on the 168 TTSX for this rifle now.

Finally got to chronograph my loads today. The 300 WSM/ R17 64gr/168 TTSX is going 3167fps and it repeated its accuracy. I'm impressed! My 300 WinMag/R23 73gr/175 LRX is going 3081fps, also repeated its accuracy. My 270/R16 53.6gr/129 LRX did not. I went on up to 54.5 and it clocked 3160fps, but 4 shots went into 1 1/2". I'm going to seat them a tad deeper and try 54.5 to 55.5 in increments, see what happens.

Here you go. I believe SAAMI standards are closer to 65K PSI for the WSM:
Cartridge : .300 WSM (CIP)
Bullet : .308, 165, Hornady BTSP 3045
Useable Case Capaci: 74.129 grain H2O = 4.813 cm³
Cartridge O.A.L. L6: 2.860 inch = 72.64 mm
Barrel Length : 24.0 inch = 609.6 mm
Powder : Hodgdon H414

I worked up loads with H414, 760, 785 in 300 WSM. All of them were initially perfect. Subsequent range trips proved to be disappointments. The dependable, repeatable accuracy was too sporadic. JB warned me of that & he was sure correct. Got no tolerance for sometimes things.
Wound up settling on H4350 for 165’s & VV N550 for 155’s. Fully reliable on race day.

Was able to shoot my 300WSM the other day after I ran the 20 fire lapping bullets.Prior to lapping I was getting 3080fps with 64.5grs of Win 760 and 3137fps with 65.0grs of Win 760 with a 168gr Nosler Ballistic Tip.After lapping,using the same bullet and powder,66.0grs 3113fps and 66.5grs 3167fps.The 168gr bullet is just a little longer and I see about 20-30fps slower velocity than I get from the 165gr using the same load.
