How much does your gun weigh and how is the recoil??
It weighs 16 pounds with the scope. Recoil is STOUT with the 220 Sierra. Significantly less with the 210 Berger. Seems that way, anyway.
Barnes 180gr tsx
Rhino 19 ( equal to RL 19) 66 gr
Berger 175gr hunting
Wit. n-560 69gr
Nosler BT 125gr
COL 72 mm
Nosler BT 165gr
Wit n-560 70gr
All this 4 loads group very vel, berger and Barnes best.
Was shooting out at 1000 yards last weekend...
66.5 grains of H4831 with a 210 Gr Sierra HPBT MK was giving about 2850 FPS at the muzzle and grouping in the 6 inch range. vertical was a bit flatter than this. Although the wind was holding pretty steady, I did get caught in a few changes that I ignored when measuring the group.
At 300 yards this group measured about .8", just over a 1/4 MOA, my best group to date. ES when chrony'd was +/- 8 FPS from average.
Gun is a Tikka T3 with 26" heavy profile rock creek barrel. Looking to get a 30" true-flite in the fall
A little different load but 23.0 gr Trailboss, wlrm, winny brass, 110gr vmax is pretty awesome. Very low recoil and wrecks hell on groundhogs inside of 250yards. No velocity measured yet but I'm guessing around 22xx-2400 fps.
Good thread as I am just starting to get into reloading for my .300 wsm with a 26" 1 in 10" heavy barrel. Trying to decide what bullet weight to use. I want a good range load as 98% of my shooting is long distance at the range. I also want to be able to take this load hunting once or twice a year. I am thinking about the berger 210 match hunting VLD for its higher bc which should help in the wind. How would the heavier bullet affect barrel life? Any suggestions? When will this guide be ready?

DAZZH - 74mm is 2.920", factory max. OAL is 2.860". My new build in 7mmWSM is finished - just waiting to go to the range for load testing, (Friday morning I hope) but mine are at 2.941" which is 10thou from the lands. I did fire one test round of 63.5gr AR2213sc OAL 2.860" with no obvious problems.
Here's my favorite load for hunting and accuracy in my inexpensive Weatherby Vanguard (yes the black synthetic stock).
68.0 gr Reloader 19
165 gr Sierra GameKing HPBT
CCI 250 LRM primers
velocity I would estimate at 2950 fps
OAL is 2.89"
This round is the most accurate I found so far in my plain ol' weatherby. It puts 5 shots into a quarter sized hole at 100 yards.
I've also had good luck with this load:
Reloader 19 - 70.4gr
125gr Nosler Ballistic Tip
about 3200 fps
It spreads just a bit horizontally but the vertical spread is nearly zero at 100 yards.
Interestingly, nosler 180 grains shoot exactly the same at 100 yards as the 125's do. Weird, I know
RL19 - 64.4gr
180gr Nosler Ballistic Tip
favorite hunting load
165 grain nosler ballistic tip seated back .015 from lands( will be too long for most magazines) 55.5 grns Varget( yes Varget) win LRP
shoots 1/2 moa out to 300yds in my rifle at 2850 fps. Killed 6 bucks past 3 seasons, three at 290yds, no one ran more than 50 yds. can ruin alot of meat with poor bullet placement though.
Tom-South Carolina Deer Hunter
HS Precision 2000P (Handcannon)
165 gr Ballistic Tip
Reloader 15 (60 Grains)
super accurate (less than .5 moa@100yds)
I have a Rem. Titanium 300 wsm 24"bbl 1 in 10 twist stock bbl. Had some minor gunsmithing done to it a little for accuracy but more for lightening as its a sheep gun. It only weighs 7lbs scope and all. Just getting started into the reloading world and was wondering if anyone on here could help me out. I've been shooting 165gr Barnes vor-tex factory ammo. It shoots a 1" group at 200 and 8" at 700yds. I bought some Barnes tsx hpbt bullets to start with just not sure what to go with for powder, primers, AOL's and so on. I was going to use these factory fire formed brass? The reloading manual i have doesnt have this bullet type listed. I didn't see anybody using these bullets in 165gr on here so might go with something else next time but need to use them up. Any info would be greatly appreciated. Thanks and good shooting.
Hi guys, Im about to start load testing a McGowen 30" SS BB in a Savage 12 target action. Im going to be trying 230g Berger Hybrids though there are no loads concerning them here.
I'm looking to use AR2213sc which is the same as your Hodgdon H4831.
Is anyone shooting these in a 300wsm and if not, why not?
I'm shooting Berger 230 Hybrids in .300 WSM. The chamber has a .280" freebore, allowing seating long enough to clear the neck-shoulder junction. Cartridge OAL is 3.260, which represents a .015" jump. Brass is Norma .270 WSM necked up in two steps and turned to .012" wall thickness. This provides a .3325 loaded neck diameter and .0045" diametral clearance in a Ã˜.337" chamber. The barrel is Ã˜1.25 straight and 34" long, primarily for weight. Action is a BAT 3LL147OCTPIC installed in a Manners Composite F-Class stock. [br]
Best load, so far, is 68.7 grains of IMR 7828 SSC over TulAmmo (Russian) KVB-7 LR primers. Instrumental velocity at 15' is 2941 fps. Adding approximately 6 fps provides a corrected muzzle velocity of 2947 fps. The primer edges are still round with some flattening in the center. I believe this is a full pressure load within SAAMI specs. There are no other pressure signs. The load shoots well, as seen in the attached target. The last shot, of course, is the one I pulled. Even in a rifle that weighs almost 22 pounds, this load has a lot of recoil. Proceed with caution.
I am working up a load with 7828, because that is all I could find in a 8# Jug.
Fed 215 M primers
Remington brass, turned to .335 loaded round in a 338 neck chamber. 208 Hornady match
Seated just touching at 3.08
Douglas 1-10 twist 30â€ with brake.
Shooting from a wooden table At 500 M. One wind flag at 385 Its always windy here in Kingman AZ
Thatâ€™s my excuse for the horizontal and I am sticking to it.
Seams to have a forgiving sweet spot as the target would indicate
I'm shooting a clunker small shank savage 300 wsm "cardinal Sin". 30inch Criterion 10 twist bull that wad a 308 barrel for about 15 shots. I shoot 200 gr smk with 72 grains if H1000 with wolf lrm primers and its a hammer. I have it in a master class stock and a Sightron SIII 10/50/60 FINE crosshairs. it does shoot really well I also will be trying N170 tomorrow with the 208 and heavier. I havent tried 4831 but ill try that soon also. I will be getting a muzzle break soon just to make it more pleasurable to shoot
MY QUESTION IS. WILL THE 12 TWIST DO ANYTHING THE 10 TWIST CAN I'D LIKE TO GET RID OF ONE JUST UNSURE WHICH
The answer is no, a 10" twist will stabilize the heaviest bullets at .300 WSM velocities. A 12" twist is only good up to medium weight bullets. I have a 10" twist .308 tactical rifle that shoots Berger 155.5 Fullbores very well. Stick with the 10" twist.
did this ever get published ?
available where...or just print all ??
This is the load that I cooked up for my buddy's Savage 300 WSM: 200-grain Nosler Partition, 67 grains of IMR7828ssc, CCI mag primers, COAL 2.815 (Nosler specs). Sub-minute shooter at 100. He was dinging gongs at 1000. Not chrono'd, but should be about 2850.
