240 Factory Ammo COL

240 Factory Ammo COL
« on: January 11, 2019, 04:26:53 AM »
I hope to have the 250 in a few months' time and figured for a start I would duplicate the (previous) factory ammo and see how I go.

Can somebody assist in providing the COL for the 85gr TSX factory ammunition, either to the tip, or to the ogive measured with a comparator, although those might also not all be identical in size, it will get me pretty close.

Sure, I can measure jump etc myself and play around, but was wonderign how the factory load was set up.

Thanks for any help.

I shoot cases with a belt because I feel the other cartridges need to pull their trousers up.

Just my .02 cents:
I would load to Weatherby premium plus factory lengths and then concentrate on concentricity. Once fired brass that is annealed and neck sized will probably yield the best results. If Weatherby is roll crimping then you should too. I think when you try to measure the jump to the lands you're going to be in for a shock. You may need to cast the chamber in order to get an accurate distance. Don't be surprised it you find that the free bore diameter is slightly less than your measured bullet diameter. This is why concentricity and once fired brass are the key's. The closer to "on axis" that your ammunition can be, the quicker and better the bullet will stabilize.

Sorry... Yesterday was the last and final day for any and all complaints whatsoever.

I try to avoid temptation unless I can't resist it.

Haha, absolutely, thanks King for the number. Thank you HDH for your input.

I've been employing precision reloading principles for quite some time now and focus on what you have suggested and spend too much money on all matter of tools and gadgets! As Weatherby ammunition is virtually unavailable here and the 85gr TSX is no longer loaded, I was just keen to get a number to start to play around with.

By the way, as we know from the long throated Weatherbys jump is not everything. I have quite a number of European rifles and these often feature long throats. I have a Sako .308 Winchester that shot five shot groups with ammo I had for another rifle into 11mm (less than 0.5") at 100m and it is loaded to more than a full 0.25" jump (7mm) for that Sako.

I shoot cases with a belt because I feel the other cartridges need to pull their trousers up.

My 240 really liked the 85 grain,TSX factory load so I purchased about 10 or 12 boxes when I found it on sale at different places on the net.Don't know what I'll do when I run out,but only shoot 8 to 10,maybe 12 rounds a year out of her.Do most of my main hunting with the 224 magnum.Shoot my 6.5-284 a lot during deer season too.I have gotten to where I carry it a little more than my 240 because I feel better with it on long distance shots on pigs.
