I went to the range to put my load work for my Savage 116FHSS 300Win Mag to a final test by shooting five shot groups. I adjusted the OAL from 3.340" to 3.3195" The bullet used is a 180gr TTSX. The brass is Winchester brass with CCI250 primers. There were three powders that produced the best three shot groups and highest velocities out of 7 powders tested last week. The three powders tested today shooting five shot groups were RL-22, W-760 and MRP. MRP was by far the best performer in a five shot test as the target indicates below and the velocities were exceptional for a 300Win Mag with this level of accuracy.

180gr TTSX, MRP, Win brass, CCI250 primers, 3075fps with an OAL of 3.3195" group size is .333"

Nice group....... but you failed to list the distance.

very nice grouping. I have used Rel22 in the past but have not tried the MRP for 300win. Looks like i should after seeing your results.
The ttsx is a barnes bullet? If so glad to see your rifle likes them, i have had mixed results with the barnes tsx, so i now shoot 180 accubonds and really like their performance.

It is a Barnes bullet but most folks don't realize them really need a jump to the lands and if so will give great accuracy. If you will notice in my post I adjusted mine even father away from the lands than than when I did my initial testing and it improve my grouping.

Most bullets will be more accurate using that method and i load that way, but they still didnt perform as well as the noslarBT or accubond. Well on paper they didnt perform as well- on deer- OH DAMN they are effective. On my custom guns i have my chamber deminsions so getting thousandth off the lands is a little easier on them. I have shot a lot of rounds of the BT and it always does well i have probably shot about 200 to 300 accubonds so far but am impressed with them so far.

Until my MRP comes in, I went a head and bit the bullet and ordered two pounds of Ramshot Magnum. reasons, 1. It is a double based spherical powder that is coated so it is not temp sensitive and should give not only 15 - 20% longer barrel life than extruded powders, but since it is not temp sensitive it will not have as much Dev as other spherical powders do - therefore being consistent in accuracy like extruded powders. 2. It is at the top of the velocity chart with Quick Load program for a 180gr TSX. 3. It is a very clean burning powder. 4. It will be easier to use as a compressed load than extruded powder. I sure hope it is as accurate as some say it is. One thing for sure I will find out pretty soon.

My Ramshot Mangum powder is suppose to come in this week and I have also received some 150gr TTSX's that I will be trying and I am confident that they will shoot well in my Savage 116FHSS because it does not seem to care what weight of bullet I use.


ACCURACY EXAMPLES:

At 100yds this180gr TTSX five group size was .334” moving 3074fps

At 100yds this 208gr A-Max five shot group was. .528” moving 2945fps

At 100yds this 165gr Sierra G/K HPBT five shot group was .389” moving at 3245fps

Very Nice shooting indeed.

Thanks man, this Savage is a real shooter.

Savage has done a great job in listning to what the shooters are wanting and then building a very accurate gun at a good price.
They are out doing remington at a rapid pace, the last few new remingtons i have looked at have had crappy workmanship, the action to stock fit is freaking terrible on most. The savages i have seen are very well built. i am drooling over the 110ba in 338 and the 10fcp in the mcmillian stock.
