Home Forums Reloading Big Game Rifles .300 wsm woes

Try RL 17 with 165/168 barnes ttsx bullets, my M70 shoots 3/4 inch groups with 66.5 gr RL 17 and the 165 gr ttsx. If that don't work then trade in the 700 for a M70.

hey all

Been trying to get a mostly stock rem 700 .300 wsm to shoot reliably. best group has been about 3 inches at 100. stock has been removed and bedded, barrel has been floated, and that helped a little. Bullet/powder combo has been 180 grn partitions, and IMR 4350. any ideas would be greatly helpful.

Thanks

....................Variety! Variety! Variety!

Many variables here.

More bullet variety is needed other than just the Nosler Partitions. IMR 4350 is a pretty good powder choice for a 300 WSM, but there may be other powders which might be more accurate for "your" particular individual rifle. Try some H-4350, RL17, IMR 4007, N150 to name a few.

You are also going to have to play around with your seating depths to determine what bullet jump distances your rifle happens to prefer the best.

Everyone here can give you their favorite powder choice, a favorite charge weight, an OAL, their favorite bullet choices and so on which gives them the best accuracys from their rifles. But their 300 WSMs and my 300 WSM,,,,,,,,isn`t your 300 WSM.

From the box new using factory ammo and prior to my reloading for it, my Ruger 300 WSM never had groups exceeding 1 5/8". No bedding or free floating from Ruger. Since new, I tailor my loads (powders, bullets, etc) and seating depths to what the rifle prefers and not to what I necessarily prefer. I recently had it bedded and free floated. Now most of my best groups are under 3/4" with some at 1/2".

Buy the rifle new? Buy it used? No scope issues? Scope mounts tight? Bore in good shape?

If all of those issues are OK, then expand your loading variety and adjust the OALs in 15/1000 increments.

No short cuts.

RL17 with no compression and Magpro with 7% compression is what I'm going to be running in mine with 180's.

Same powders but 10% compression for the Magpro with 168's.

But then, I'm a speed freak.

Speed doesnt mean accuracy. But ya cant teach stupid.


Swifty

I have been shooting 168 tsx's over 65 grain re17 at 3100 fps and it has been a very accurate load in my model 70. Now a friend with a 700 in 300wsm found that 63 grains of re17 at 2900 fps was the ticket for him.

Re19 also has worked well.

I have found that max loads are rarely the most accurate.

Wild groups like your 3" at 100y. are usually a rifle or scope problem as long as your aiming well. Its not the loads most of the time.

Since you have 'bedded' the stock its not going to be as easy to sell the rifle and move up to a better one.

Change the scope and check the mounts.
Scrub the barrel clean with a lapping compound.

Bring a screwdriver to the range with shims for the barrel and action.
Shoot it starting with tight action screws and later with the rear screw not as tight.
Shoot it with the magazine box out.

If this does not work bring the rifle home and recut the crown yourself.

recut a crown

If all that fails get back to us.
