Good 270 Weatherby Loads
« on: August 03, 2017, 07:35:09 PM »
A co-worker of mine recently purchased a 270 Weatherby...Accumark...I believe. He wants to shoot/reload Nosler 130 gr Partitions and Accubonds.

I've had good luck with Reloader 19, which is listed in the Nosler manual as the most accurate powder tested.

Anyone else have a great pet load for the 270 Weatherby?

I've had good results with IMR7828ssc, Accurate MagPro, and RL19 with 130 in my 270Wby. Nosler data is good, but in many instances, their listed velocities are higher than I've achieved in my rifle.

I've had good results with H1000 using 130gr. Partitions and Swift A-Frames.

Does anyone have a load for the Hornady 130 grain Spire Points?  They shoot very well out of my Dad's Custom Euromark so my plan is to stick with them since they work so well and are so accurate.

What works in my 270WBY from 1958 is not for everyone. Mine is 1 in 12 twist rate and is limited to 130gr. or less to stabilize.  It's best is 110 gr. TSX which Barnes recommends as the limit in mine. I don't see that as limiting any game animal I would use it for, but damaging that stock relegates that 1958 deluxe to the target range.  :)

Regular IMR7828, about 75g will give you around 3500 fps.

The factory loaded 130 gr spire point's shoot very well in my ultralight. I was able to pretty much duplicate the factory loads using MRP and IMR4350, with the 130 gr spire points, 215 primers, and the same OAL as the factory loads. I forgot the mention in my previous post, MRP works well, with 130's in the 270 Wby, if you can find it.

What charges are you using with the IMR4350?  I'd rather stick with that powder since it's easy to find.

I'd be curious to hear what the factory COL is on the 130 great Spire Points, as well, if you don't mind. It will be Bea good point of reference if I ever decide to try the other half of this box of Interbonds I have on my shelf. Never could get then to tighten up like I wanted. Took some work with the E-Tips but they're running along nice and tight so I am good there. But I'm running them markedly shorter overall than i ever ran the Interbonds.

I had to do some looking for my notes, I started do reno's on my reloading load last winter, and don't have it done yet.  ;D
These notes are based on my ultralight(which is picky on loads) only, I have never tried any of these loads in my other 270 wby's, so I don't know how they did in those rifles.

The norma website and info I got, says they load the ammo to a OAL of 3.228", but my actual measurement of factory loads are 3.20". The factory 130 gr spire point load, shoots on average just under 3/4 moa, at a chrony speed of 3355 fps.

With 68 gr of IMR 4530( max load), 130gr spire points at 3.20", I get 3/4 MOA and a chrony speed of 3347fps. Loads from 66gr -68gr was accurate.

With 74gr of MRP,130 gr spire points at 3.20", I get just under 3/4 MOA, at a chrony speed of 3362 fps. Loads from 73gr -74.5gr(norma's max) was accurate

Just in case someone else is interested in a few other factory OAL's for the 270 WBY

factory 130 gr TSX load OAL- 3.250"
factory 150 gr spire point load OAL- 3.210"

forgot to say, with the 130 gr interbonds, I haven't found a load yet I real happy with in the 270 Wby's (1-1 1/4 moa) They shoot well in my old 270 Win, so I just been using them for it.

Catskinner, thank you for the info, I'll try that load.  The load I have for my .270 Winchester is a Remington 9 1/2 Large Rifle Primer, 52.0 grains of IMR 4350, and a 130 grain Sierra Game King head.  I get 1/2 inch five shot groups with this load in my Vanguard VGX.  This load is the duplicate of the Federal Premium Vital-Shok Ammunition from my experience in that you can interchange both bullets and they have the same point of impact and group the same.

Chris,
Did you ever take the vel of your 270 Win load. Just curious, because I.ve got two 270 Win rifles and am not very impressed with  their velocity.
Thanks CR
