Mine is a push-feed Model 70 with a 24" Schilen barrel (1:12) and McMillan stock.
Using Norma cases or Necked up W-W .338s and Federal 215 primers.
Norma factory loads with 250 Woodleighs went 2702fps over the chronograph.
The outstanding powders with 225gn bullets were Reloader 15 and Varget. Also had some excellent groups and good velocities with IMR4350 and H4350. IMR4831 gave great accuracy but not enough could be stuffed in the case to reach top velocity. The best 225gn accuracy load was with Reloader 15 and TSX bullets at 2940fps. Nosler Partitions and Ballistic Tips were nearly as good.
H4350 was the star with heavier bullets, exceeding 2800fps with 250s and groups under an inch. It also pushed 280 Swifts to 2680 and 320 Woodleigh solids to 2490 without exceeding the factory load expansion ring measurements by more than .0005".
Have fun with your .358
