.35 Whelen acquired, now optimizing.

I topped out at 56 gr I believe for about 2650 fps, I'm going to revisit that load here shortly since Sierra goes higher than that.

I stopped at 55.5 and the primers were getting pretty flat. 60.4gr is yeesh. Did you ever establish the most accurate charge for your gun? looking for the velocity based on charge that others have found was happy land.

At 56 gr it grouped fairly well, a bit under MOA if I remember right. IMR 8208 been a standout with 200's though. I'm going to try CFE 223 with 225's this year too to see how it does.

That helps a lot. I'll creep up to 56.0 and see if the groups shrink. I could see the groups get smaller as I went up in charge weight. I wondered if there was a node just a little higher.

I’ve had great in my 35 Whelen with the 225 gr SGK and CFE223.

Where did you end up?

 

[JD338]

I’m loading 67.5 grs CFE223. It’s more than enough for what I would use the 35 Whelen for and I have bigger clubs if needed.

Awesome, thanks.

Did you switch to a mag primer or did you shoot this with Large rifle primers?

 

[JD338]

I did switch to a Federal GM215M primer

I played with many of them. My most direct route to success was CFE223 and Ramshot TAC with the 200 gr TTSX . 61 gr TAC is good for 2850 fps and well under sub MOA
65 gr CFE 223 about 2700 + and again sub-MOA. Both are started by the WIN Large Rifle primer, but a mag cap would not hurt either.

I take a more traditional approach with 55 grs. of RE15, standard LR primers and a 250 grain Northfork semi spritzer at 2500 fps with single digit SDs. Hasn't let me down on 2 safaris and 8 animals.
