Just a thought! The .17 Remington may not be as hard on barrels as the .17 Tactical or possibly the 17-223. It just depends on your needs. There has been a discussion from time to time about the .17 Tact. and barrel erosion on the Saubier forum.

Here is one person report of using the .17 Tactical
"Kdog--I have only used Varget an N-540 in my .17 Tactical with 30 gr. Golds and 25 gr. V-Max bullets. I used .20 TAC Dakota Lapua brass and Remington 7½ primers.
My fire forming loads with the 30 gr. Golds were with 24.5 gr. of Varget and I also did fire forming loads with 24.5 gr. of N-540. Muzzle velocity for the 24.5 gr. load of Varget was 3,906 fps and the muzzle velocity for the 24.5 gr. load of N-540 was 3,857 fps. These bullets were coated with Danzac.
I also fire formed brass using 25 gr. V-Max bullets and that same powder charge for N-540 and was around 3,900 fps at the muzzle. I had the barrel set back one full inch after only 521 rounds down the barrel. After the set back this same load was then giving me about 3,850 fps at the muzzle while fire forming brass. The first three or four inches of the barrel still look like and alligator hide even after the one inch set back. The rifle is still fairly accurate--accurate enough to hit young prairie dogs a little over 200 yards with seeming ease.
Right now, I'm using 24.6 gr. of Varget and that load is pushing the Danzac coated 30 gr. BTHP Kindler Golds at 3,792 fps for muzzle velocity. I only have 745 rounds total down the barrel so I'm pretty disgusted with barrel life with this caliber, but like I said, I'm still hitting prairie dogs at 200+ yards, but how much longer that will happen, I do not know!!!
