Re: Reload 17 for 300 WSM

I read somewhere Barnes worked pretty good seated at 50 thousandths (.050) off the rifling. Problem for me was that they won't fit in the magazine then.

Re: Reload 17 for 300 WSM

I've noticed some significant differences with different rifles. I have a Browning A-bolt that absolutely loves 67.5 grains of RL-17 and a 168 E-tip at 2.840 and 3200 fps with no pressure signs. I had to scale the load back a bit to run in a Win 70 300 WSM.

I know some may argue, but I generally use burn rate as a starting point to work up loads when data isn't available. Using the burn rate of RL-17 I've noticed that my load charges are very similar to H4350 for each given rifle I've used it in.

For those of you that have already worked up a load using the TTSX what are you using for you OAL and how far off the lands are you? I was thinking about starting off at 30 thousandths (.0030) off the lands.

The TTSX will jump fine. As for seating depth I would try a general COAL at around 2.84 and see how that does. Once you find a potentially accurate powder charge you can start tuning the seating depth. Get your powder charge first. Your rifle will tell you what it likes. In my A-Bolt most of the bullets I shoot will shoot well seated between 2.84 and 2.85.

Re: Reload 17 for 300 WSM

Did some measuring last night and my max COL is 2.965 (touching the lands). I was initially thinking of backing of off .03 so my first loads would be right at 2.935. From all the loads that I could find most were between 2.9 and 2.84 with Barnes manual suggesting 2.84. Should I start at 2.84 and work up a powder charge and then play with seating depth or should I start with my original plan of 2.935? I did put together a dummy round last night at 2.935 to see how if feed and if it would work in the magazine and everything seemed to work out fine.

Re: Reload 17 for 300 WSM

Unless your gun is a single shot, IMO your are wasting your time measuring the lands and working from there as the round will not fit in the mag.

Got to ask why?

Start at max magazine COAL and work from that.

the barnes are designed for jumps and big ones, at .03 and similar intervals you will wear out 5 barrels.

Make big jumps and then fine tune between the best nodes for an acceptable group for what you need. If .5 MOA works for your gun as hunting rifle, then do you really need to get to .4?
