Re: Bullet seating depth and load suggestions for Tipped TSX?
Thanks for the suggestions guys.
I finally had some good luck with the TTSX and RL17 today. Wind was calm and temp was around 55 deg F.
My rifle: Remington 700 CDL SF .300 WSM with HS stock and sako extractor.
I weighed the bullets and all 3 were within .1 grains. Did not weigh cases.
I used brand new Winchester cases and Federal 215M primers.
I seated the bullets about .050" off the lands which in my gun gives a COL of 2.825"
64 gr resulted in an average velocity of 3062 fps and .3" 3 shot group that was a clover leaf. This is the best group to come out of my gun this year.
65 gr and 2x fired Norma cases trimmed to 2.092" gave around 3115 fps and a group around 1.25" although i may have pulled that one.
66 gr and once fired Federal cases trimmed to 2.092" gave around 3160 fps and group of .75".
This is 2 grains under the max load on Alliant's website for 165s.
I stopped here because the wind picked up.
I have shot up to 66 gr with 180s at over 3100 fps before but that seemed pretty warm.
I shot a bunch of 1" groups with RL15 and Varget but nothing spectacular.
