Home Forums Reloading Big Game Rifles New .35 Whelen data from Speer

The new Speer data for a 250 gr bullet in the .35 Whelen shows up to 2700 fps! The highest velocity powders they show are 2000MR, CFE223, Power Pro Varmint.

I have not seen/heard of these 3 powders being used in the Whelen.

Anyone besides Speer actually try these? How'd they work?

Their new data looks very good, I'm going to be looking at some of those new powders for my gun when I develop 225 gr and 250 gr loads. The data with the 180 and 220 gr FN bullets looks equally as good. Now we just need them to develop a new 225 gr Gold Dot BTSP for the 358 Win and 35 Whelen.

Can anyone post a link to the new .35 Whelen data? Thanks.

For those that haven't seen it you can find all of Speer's data including the 35 Whelen here.

I wish Speer would include test barrel lengths in their data.

I saw that and am going to try some of the new powders.

While neither is new I am getting good results with the 180gr. FP in my .35 Whelen using the IMR 40464 starting load which pretty well fills the case.

Many of their loads appear to be hauling azz.

I'm too damn computer iliterate to open a pdf? file, cant even read the new load data.

Boy that 250 at 2700 would be a hammer!! Gonna have to play around when the weather gets better.

That's full throttle 338 Win. mag ballistics out of an '06 size case. Interesting.

It sounds like a fair bit more than my shoulder would be up for. As it is, 250's @ 2,500 fps usually make for abbreviated range sessions.

I did notice, though, that lots of their loads across several cartridges incorporate 4000 MR powder. I have a pound that's been sitting unopened on the shelf for a good year plus. I might have to play with it some.

I used to hunt elk with a .338 Magnum and 275 gr. Speer RN bullets, since I no longer hunt elk I sold the .338 and now use a .35 Whelen as my whitetail rifle. After much load development and range testing I found the 225gr. Sierra or Nosler over IMR 4064 to be the load my rifle prefers. Agreed that a 250 gr. bullet at 2500-2700 would really anchor an elk or moose and would be noticeable as far as recoil.

Truth. I’ll see what I can get outta a 22” Hart

I feel ya bro.... I built my whelen to fill the larder, with bigger critters, it ain’t gonna be at the range much, but it’ll hammer shiit when need be

What I don't understand is how come the 250-grainer is so fast, while the 220-grainer is so slow.

According to the data, the .35 Whelen with a 250-grain bullet is faster than a .338WM with a 250-grain bullet. And a 225-grain .338WM faster then the .35 Whelen with a 220-grainer.

Anyone get this open yet, I try and some windows explorer program opens.

No problems here, that's strange it's not working for you.

Don’t know where you came up with this but the 338 is faster with both the 250 & 255.
