Home Forums Hunting & Shooting Custom Rifles & Wildcats Need Load Data for .35 WSM with RL17

No new data?

77grains of R-17 with Barnes 200grain TTSX for 3180fps worked up

Hey guys just got my rem 700 35 wsm done about to load some 225 nosler accubond anyone have some advice on best all round powder to start with! Mood take temp stable and accuracy over speed! Any info would be great! I see rl17 and maybe h4895 and possibly varget??? What about h4350? To slow to fast?? Help a brother out!! 😂

I’d bet 17 would work well, along with any of the 4350’s. I’ve had a Newton and Whelen but not a WSM but since case capacity is fairly close to the Norma I’d look for 358 Norma data and work up careful. Someone with QL should be able to help you out as well, at least for beginning data.

I dunno about starting with 358 Norma data. There's damned little Norma data out there anyway. It seems the WSM case capacity is between Whelen & the Norma. My Norma brass holds 92.4gr of H20 full to the top & some Hornady 300WInMag reformed holds 92.7. I would start with a warm Whelen load & work carefully upwards.

The 250 QL data below shows 70.6 as max for A4350 in the 35 WSM. My (newer) lots of A4350 are almost as slow as S/World 4350. I have been to 80gr with both IMR & S/World 4350. SW was disappointingly slow @2650fps while the late '80s lot of IMR showed a slight ejector mark at 78gr. @2826fps. so at least 10% more powder (possibly more) in the Norma cases than WSM for comparable velocity. It seems a warm Whelen load for your chosen powder would be a safer start & expect to burn some components working upward. I did 2 shots at each full gr, then 1/2 gr. increase over the chronograph while being aware of bolt lift etc.

I dont believe that PP2000MR is in QL yet, but is a winner for speed with accuracy in both my Whelen & my Norma with 225s. H4895 & RL15 did almost as well in both with 225s.

Here's 2 35 Sambar QL I copied from somewhere on the web. Hoping the columns stay in line... but they didn't.

Guys, I completed my load development for my .35 WSM several years ago. I settled on RL17 with either 250 gr Speers or 250 gr Nosler Partitions (for Alaska hunting). I settled on 71.0 grains for the Speers and 70.6 grains for the Partitions. Both made just under 2,800 fps. And out of my 8# rifle that is a bit of recoil.
