This was a good substitute for Varget. The testing has shown that is both calibers tried, .308 and 6 BR, it is extremely accurate and giving me results very similar to Varget, although IMR 4166 is just slightly hotter than Varget. 29.8 grains of IMR 4166 gave the same velocity and point of impact as 30.3 grains of Varget in the 6 BR. For the .308, 43 grains of IMR 4166 pushed my 175 grain SMK bulltet about 110 fps faster than 43 grains of Varget. This will be a powder to be kept on the reloading shelf along with Varget for those in competitive shooting applications.

Loaded it in 243. 36.3 grains under a Hdy 100 gr interlock . Groups Great deer load with a great bullet also. Give it a try. Thanks Primers outdoor for having both in stock a while back. This works great in my model 70 super grade with Sierra Game King 150s. It’s not a fussy rifle.

308 FMJBT 147-150gn, 42.5gn 2.755 oal through either AR10 or fussy Mauser M18. Fantastic for 55-62gn 223 as well. The IMR 4064 loads transfer closely to 4166 and 4895 in above-mentioned caliber. Relative performance at sea level and high desert LOS etc are easy to build ballistics for with this temperature insensitive charge. Fast burning, ultra clean. which means ultra clean and consistent.

loaded up the 175 Match King with a starting charge (according to Hodgdon) of IMR4166 because on a newer barrel didn’t want to lay down a bunch of copper fouling so wanted a powder like 4166 with the copper eating goodies in it. 1st two at 100 yards landed a foot apart but the barrel started clean and needed to foul a little.

The 4th shot landed OK, went to 200 yards where the 5th, 6th and 7th shots landed in about a 2 and 1/2″ triangle. Now that the barrel was fouled with seven shots (which read once that bench-rest shooters claim it really takes to foul a clean barrel) It took it to a 400 yard gong in light sideways breezes. 4166 will obviously do anything 4064 will do in a 30-06, which people usually choose a powder that burns too slow in for great accuracy.
