Review of Sparks 175 TMK
Of all my rifles which by the way are all shooters. There seems to be some special relationship that my Savage 308 10T has to Sparks 175 gr TMK and specifically lot # 1911. This lot is special. I took it to bangsteel june 3rd and what I had left of it to the Clinton House 7/9/20. My results are remarkable. First the muzzle velocity is very high with absolutely no pressure signs. Savages have a very hard secondary extraction with any pressure problems. This ammo operates as smooth as silk. My muzzle velocities are very consistent. The density altitude at bangsteel on June 3 was 4500 and some change. My muzzle velocity that day was 2770 ft/sec. Fast forward to the Clinton House 7/9/20. This same lot had a muzzle velocity of 2784 ft/sec at a density altitude of 2532. My elevations on my turrets only changed because of drag. Once I was dialed in at 1000 yards which was 30 minutes that day I was shooting sub moa. I could have literally shot sub moa at 1000 all day long. I have a new lot # 802 that i am looking forward to trying this week. A friend of mine was able to try this new lot in his 308 and it was very accurate. In fact he didnt miss. If I'm not mistaken the muzzle velocity on lot # 802 was 2685 ft/sec. I tell everyone that I know about Sparks. Joe and the guys up there will treat you right. I handload and sometimes I wonder if it's even worth it because Sparks is the benchmark I compare my handloads to. Jim Turner(Long Range Shooters Of South Carolina "Upstate")

Spectacular Results
After buying expensive ammunition from my local gun store, I was disappointed with the results from my precision rifle at even 100 yards. But then I went to BangSteel long range shooting school in Bland, VA, where they recommended and sold this Spark ammunition. My precision rifle was a perfect match for this ammunition and I was able to consistently shoot targets from 600 to 1200 yards. Thanks for making such a high quality product!
