.35 Whelen & CFE223 - magnum or standard primer?

always run WLR primers
@wolfhunter
The 35 AI will need about four grains more powder to equal the Whelen. I have an AI version and find it a waste of time. Fire forming cases then reloading equals half the barrel life for an extra 100-150 fps. To me not worth the hassle.
Yes the AI is a fractionly better but do you need more than 2,700fos with a 159 gn or just over 2,400 fps with a 310gn.
I get over 1,899 fps with a Woodleigh 225 gn and close to 2,800fos with an Barnes copy the 229 gn Australian made atomic 29. Don't need any more than that.
Just my opinion owning both.

Late to this party. I will make my points, based on my ~50 years of loading;

1. There is no substitute for testing. Always take whatever someone else says with a grain of salt...even if their opinion is based on test data. Lot #s of primers/powder vary. Chambers/barrels vary. Brass varies. Loading techniques vary. It all varies!!

2. Loading density is, in my opinion, more important than total grains of powder, when it comes to the mag vs non-mag primer question. I have done a fair bit of work with mid-range loads in cases as small as 22 Hornet and as large as 470 Nitro. Any load with less than around 75% loading density with stick powder or 85% with ball powder, in a case with >50g capacity, generally ends up with a magnum primer due the better consistency afforded. But primers are never just substituted. Always work up. Lower density loads can be a nightmare with a marginal primer...even in smaller cases with less than 50gr capacity. Test!

3. Low temps definitely matter! It is simple thermodynamics. All else being equal, I will entertain magnum primers more readily when loading ammo for cold (below 0F) weather. And I always try to do my load testing at temps approximating the temps I will hunt in. Old habit from before the days of temp stable powders...less of an issue today, with some powders. Not sure if primer thermodynamics have changed as much?

Always remember #1 above, even if you forget the rest. And use a chronograph. No excuses any longer. My Oehler M33 cost an entire month's pay for a Marine Corporal in 1978. Not the case today!
 
I know what the experts say, but be damned if i can tell any difference between the two, My chrono graph shows about 100 fps or less in extreme cases and little or no differeccd in POI in most cases but that varies as to caliber..Over all I get better accuracy with my favorite primer the FC210. I would recommend using fed 210 in the 06 case and 215s in belted magnums but don't over think it.

Currently doing a load development on a .404 Jeffrey... it's always surprising to load .423 caliber bullets into a .404 caliber rifle. But we love it when we get 400 Gr North Fork SS bullets to 2300 FPS, those should hammer down on buffalo. Next up are the Cutting Edge solids and then Raptors... load 200 rounds of ammo for the customer and on to the next gun!
To much to political shit, to little Africa :-)
Spending a few years hunting out west then back to Africa!

Hello. If you haven't already sold this rifle then I will purchase. Please advise. Thank you.

I doubt you are interested in any trades but I was getting ready to list a Sauer 404 3 barrel set in the 10-12 price range if your interested. It has the 404J, 30-06 and 6.5 Creedmoor barrel. Only the 30-06 had been shot and it has 7 rounds through it as I was working on breaking the barrel in. It also has both the synthetic thumbhole stock and somewhere between grade 3-5 non thumbhole stock
