A couple of mo.ago I aquired a phenomenal gun because the price was right ,I was looking for a 6.5x284.But I found a great deal from an individual . A.300 win mag in a remington sendero with a heavy varmiter barrel and agreat adj. trigger plus it has an HS precision stock . The gunshoots moa with everthing I handload for it but it bug holes 150 grain nosler accubonds with 76gr of RL22. I put a burris 4.5 to 14 ballistplex scope on it .My bow scale says it wieghs about 11.5 pounds. I took it out to the long range [1000]yds tosight it in past 100 yds the gun shot extreamly well out to 600yds ,great groups just not where I wanted to hit. The wind was about 20 mph drifting me pretty bad at the longer ranges CAN ANYONE help with the velocity Number for the 76gr.of
RL22 and a 150 gr accubond ,I think the BC is about.435 I dont have a cronograph and also maby steer me to some simple wind wind drift tables I can tape to the stock. This is going to be one great hay stack rifle for the alfalfa patch. Recoil is less than my lighter 98 mouser in 30-06 Thanks in advance

Bugholes at 100 yds do you absolutely no good unless you're hunting bugs at 100 yds.

If you want to hit things at 600 yds, out where accuracy actually matters, try the 200 AccuBond. Even if the groups aren't quite as tiny at 100, you'll be pleased at 600. Ask yourself where the accuracy is more important. Trajectory is easy to compensate for accurately, wind drift is not.

Wayles, It's going to be hard to tell because every rifle usually chronos alittle different.

The only 300WM I've used the 150ABs and R22 in was a Model 70 and it was hitting 3300 w/ the loads I chronoed but they were around 80 grains. 76 grains is a mild load under 150s in the 300WM so, I'd guess the velocity is around 3150fps tops w/ your load. I will say that those pills will do a heck of a job on whitetails, Mulies, and hogs out of a 300WM.

Good Luck

You may want to try out the 180 gr accubonds loaded up to the max of 75.5gr RL22 which should run a little over 3000 fps. Most 300 win mags don't reach their potential with anything less than 180grs, anything 180 grs and over usually are the most accurate for long range shooting as it reduces wind drift. I will admit I haven't tried the accubonds yet at that distance, but i have used 180 ballistic tips which is practically the same thing as the accubonds on prairie dogs up to 600 yards with no problem with wind drift whatsoever even with approx 15mph cross wind. But either way, you should be fine if you decide to stick with that load.

I also shoot the 180 gr. Ballistic Tips from a .300 Win. I've shot them at 'chucks to around 850 yds. I've found winds at 5 mph or less to be a factor. By my rough figuring, you're drifting about 40 inches at the 600 yard line (assuming you're near my velocity numbers at 3050 fps). IMHO, that's a wind drift problem on elk, moose and bison........let alone PD's.

If you are serious about streching it's legs try some of these.

A heavier bullet with a higher BC will help a lot. You can do a drop & drift cheat sheet and tape it to your stock. But you still need to know how much wind there really is, and get really good at judging distance. Or get a rangefinder. You'll be impressed with the heavy VLD's. Nate
