Twins, I realize this thread is a bit dated. However, I wanted to check in to see how your CTR is shooting. I have owned one for 2 years and cannot be more happy with it. I have been able to develop some loads that are getting me on steel out to 700 yards. Good luck with the new rifle. Hope it shoots as well as mine.

Beastieboy, what is the muzzle diameter of your CTR 260? I have been trying to find what it is, but have had zero luck. I know the Tac has a 22mm .860 dia and the varmint has an .870 dia.

The outside diameter of my CTR barrel is a little over 20 mm or .82 of an inch. This measurement was taken 1 inch from the muzzle threads.

Beastie boy. Thank you so much for taking the time to do a measurement. I have ordered a CTR in 260 and a Varmint in 223 and they should be here in a couple days. Now I am looking thru the posts to get an idea of a good starting load for the rifles, mainly the 260, as I have been wanting a 260 for years, but after finding this forum and how well the Tikka's shoot, finally buying one. 🙂

Glad I could help. I have had good luck with 140 grain amax and 143 grain hornady eldx pills. Here they a couple of my “go to” loads.
143 hornady eldx
46.5 grains h4831sc
Fed 210m primer
Coal of 2.90140 hornady amax
47 grains h4831sc
Fed 210m primer
Coal of 2.87.These loads are pretty slow at 2570 and 2600 fps respectively. However, they are extremely accurate. Dime size 5 shot groups at 100 yards accurate. I have been using prime brass because I had it on hand. Purchased some Lapua brass 2 weeks ago. I am hoping better brass will get me a little higher velocity. Also, I just scored a couple pounds of h4350. Have read good things about increased velocity with h4350. I have a bunch of new test loads awaiting my trigger finger. I will make sure to post some results of those test loads. By the way, I believe the biggest factor in my load make up is the coal. So far, different charges have not really had too much of an impact on accuracy. Adjusting my coal has really been the ticket to tightening groups.
