What is the bullet number listed by Hornady in your manual?
What .25-35 do you have?
The Speer hollow point works very well in our .25-35, .25-35AI and the .250 Savage rifles.
If you decide to try a contender barrel consider the .25 Bellum, .25-35 Tomcat or the .25-35AI. The straighter case shape overcomes the limitation of the Contenders extractor. I don�t remember the details of the .25 Bellum but the .25-35 Tomcat was designed to be formed from .30-30 cases without inside neck reaming. When making .25-35 or .25-35AI cases from .30-30 or .375 Winchester cases it is necassry to inside ream the cases � not a big deal but an extra step.
The Secant ogive on the Hornady bullets and most other jacketed spitzers begins to taper quickly ahead to intended seating point (whether or not it has a cannelure). Even using 100% load density still give you a problem when trying to apply a crimp.
The .25-35 is just too much fun for words. A great plinker, fine small game rifle and adequate for deer.
