Re: .35 whelen loads
I've read good things about the RL15 but since I didn't have any, I'm using Varget and 225gr TSX bullets.
Mine is an old ADL rebarrelled with a new CDL takeoff. The action and 1" of the barrel is bedded, then free floated, with a trigger job, decelerator pad and vxII 4-12x40. I don't have impossible accuracy expectations for this gun, and I'm happy with it.
If I stick with cold bore shooting, I'm holding 1.25" groups at 150yards. I'm using 57gr Varget to produce just under 2600fps. During initial load development (Jan-Feb) I achieved 2700fps but didn't feel good about it - very flat & cratered primer. Besides, I'll be hunting mostly in summer with this gun (pigs) so I don't want any surprises. This should be hell on pigs!
I used winchester 30-06 brass, run straight through the 35whelen RCBS FL die and now I partially size without bumping the shoulder. Seems to work nicely. The brass was substantially shorter than spec, so I didn't trim at all, even after 3 firings. I just did the standard flash hole debur, ID/OD chamfer, polished the case mouth and primer pocket uniform (now just a primer pocket brush) Recently I annealed some of my brass - we'll see if there's any effect on accuracy, I doubt it...
