Info for .35 cal TSX load

[WhelanLad]

Hi guys.
Im wanting to load up some TSX FB 200gr .358 in the Whelen.

1stly to see where the POI is at 100m compared to my current 225gr Woodleigh RN load.

which will determine if its even worth loading up more rounds to take hunting and see how they perform on a Sambar deer. (tough as nails)


I have done a bit of looking an found ADI data for AR2208 (varget) , Min is 52gr and Max 57gr


I currently load 55gr for the Woodleigh RN, and think I would start with that for the TSX and load 5 rounds.

I would like to know the seating depth & coal for this combo please


Also your thoughts on the performance of the 200TSX and 2550-2600 FPS for use out to 200m.


Im using RP brass- Fed LR primers.

And lastly do you think the POI will be anywhere near the Woodleigh load? est vel-2500fps

Thanking you muchly

The 225gr TSX is what I load exclusively in my Whelen. 58gr of Varget gives me 2700fps in my Ruger with a custom barrel. I don't have the exact COAL right now but it's loaded to magazine length.

Myself, I'd start my first loads with a bit more caution- closer to the minimum rather than mid to upper end of the suggested range. Tsx bullets are solid copper and they tend to respond differently than cup and core lead bullets, the most common issue being the tendency towards higher pressures with any given powder charge versus lead core bullets.

Whether or not your two loads will shoot to the same point of aim can only be answered with one word; Maybe! The next question is whether the difference is small enough that you can use both loads without a sight adjustment. If the velocities are similar, the chances are that the difference in POI will be small, but until you get out and shoot, you won't know.

Whenever I use the TSX, I seat to the forward groove, and pay little attention to the jump to the lands. Ease of cycling matters more to me than fractions of a minute of accuracy. Because the crimping groove is so convenient, I crimp when I use these bullets. This tends to uniform the bullet pull weight, which negates the purported advantage of optimizing the bullet jump anyway. It also means the ammo can be used conveniently in more than one rifle.

I agree that 55 grs is an appropriate starting load, as you already know how your rifle behaves with that powder charge under a heavier bullet.

The POI will be a bit different due to the difference in mass of a solid copper vs a lead cored RN.
There's .35 Whelen data on Barnes' site, but it's limited to 3 powders. 2 per bullet weight. They want you to buy their manual. The data using IMR4064 shows 113 fps difference between a 200 TSX and a 225 TSX, that and the difference in mass will change the POI, but likely not by a great deal.
