MM .360 280 gr Mold

Postby Knox » Tue Oct 27, 2009 9:54 pm

Dan,
A little over a week ago, I received a mold you cut for me and it has been fantastic. For the .35 Whelen, I've tried a few production molds in the past mostly with failure or they're so hard to find, it cost an arm and leg to purchase. So far, with limited time to experiment, it hasn't been hard to work up a load to make these things shoot well. Cast with WW, sized to .359", gaschecked and heat treated to 20 BHN with a load of 51.0 gr of RL-15, my first 3 loads at 50 yards went into a nice .430" group and the second 3 shots went into .350". Rifle is Win M70 with 20" barrel. Avg. Velocity is 2212 fps. Now to get out to 100 yards then 200 to see if they will stabilize in this slow 1 in 16" twist. Great work on the mold! I look forward to more of them.

Awesome photos ! ! !

I'd like to take credit for the good shooting, but I'm sure that was due to you creating a sensible design. Plus a little luck. :lol:

Thanks for sharing. I love it when customers post results.

A little more about sensible design. What you did was create a design with lots of bearing length, and a short ogive. I've preached on this over and over, nice to see someone doing it.

Lots of bearing length is usually always a good thing with cast. This particular rifle has a deep throat and this bullet engraves into the rifling just enough to get it lined up and straight. On the other hand, the other Whelen I have has a short throat and the bullet still fits up nicely into the rifling without any problems. Me, being the way I am, I hate to use up extra powder space with such a large bullet, so this seemed to be the most sensible approach. By the way, those are lubed up with Lee Liquid Alox. So far, I used it on cast up to 2600 fps without a hitch. It's now becoming my favorite lube. I think that a bullet that is nice and oversized is a large contributor to being able to run at high speeds as well.
