I read this thread a week or two ago so I went and picked up some PP Varmint and MR2000.
I could get the 200 TSX going about 2950 with a book max charge of Varmint from my 20" Whelen but accuracy was better between 2815-2850.
MedRiver, I never found a published load for the 200 TTSX (or any 200 grain bullet) with Varmint, so I interpolated between Speer's Varmint maxes for the 180 and the 220 to estimate what max would be for the 200, then worked up to confirm it with two separate bullets. I got about 2975 (in 23" barrel) which comports with your 2950 from the 20". Would you please share the source of your book max for the 200 TTSX with Varmint - I'd like to see how close I got with my estimates.
Thanks, Rex
My "book" charge was a simple interpolation between their 180 and 220 grain data. I went up to 67 grains to hit 2947 with the TSX. From the brass it looked like I could keep going but figured I was getting pretty warm by then so just went to shoot for accuracy. 64 grains gave me about 2815 and the best accuracy.
HA!! That is exactly the same way I got to my load! Great minds work alike, obviously! Here's a discussion on another forum where I posted my load work with 200 TTSX and Varmint: My 200 TTSX Varmint load development Cheers, Rex EDIT - when you go to that link you'll have to scroll through a bunch of yammering to find the posts of mine outlining the load development...
