Re: Loads for .300WM-.300WSM

Now that I'm settled in with a good load for my Rem 700 300 wsm, I'm finally ready to get to work on a load for my Win 70 300 wsm. Fellow Hider MALLARD gave me some good leads on this load. The initial ladder test was hard to pick through, because it was the tightest ladder I've ever shot.

The picture below was String #4 of the 2nd stage of load testing. If it wasn't for the flyer, I would have shot my best group in load testing ever. I don't shoot 100 yards groups routinely (Now mostly all on steel at LR), but I could tell that the pressure got to me. LOL

Re: Loads for .300WM-.300WSM

My rifle is a Stiller Action with Rock 1-10 barrel and 24 inches long. Barreled by Chad Dixon at LongRifles,Inc.

My 300 WSM hunting load is as follows:
Remington brass: body sized and lee neck sized
Primer: CCI BR2
Bullet: 185 Berger VLD
Powder: 67.5 grains of H4350
Speed based on CED Chrono at 20 feet: 3024 fps average and over 3700 ftlbs of energy.

Group: 0.4 inches at 100 yards off a bipod.
They are seated about 25 to 30 off the lands at 2.265 to the ogive.

Re: Loads for .300WM-.300WSM

I get about 2775 fps from a 210 Berger VLD from my 300 WSM using H4350.

I am doing load development right now for .300WSM / Berger 230 Tactical OTM (Re-22), and for .300WM / 225 Hornady (Retumbo).

Blew out some primers with .300WM / 225 Hornady / Fed215M / 76.5 gr Retumbo / about .020" jump. Backed off, starting again.

Just got some data last week with my 300wsm with a 28" kreiger in a long action. With a 208gr amax I am at 3010fps with a warm dose of re17.

I could go higher I think but my primers are looking a bit cratered. Im using cci BR-2s to keep my es smaller. This load is accrete, all five at 100 can be covered by a quarter, and that's on a windy day.

 

[rusty815]

Re: Loads for .300WM-.300WSM

Thanks ejd049, I was hoping to get a little more room to be able to seat longer bullets, but the 2.980 I'm seating bullets is just fine and will have to do.


Jeepocabra primer cratering is usually not seen a sign of overpressure, at least from the people I have talked to, since it is usually something else (such as an oversized pin hole) that causes it. I know that 2950fps is possible out of a 24" barrel, so I suppose you can get a little more out of a 28" barrel, I suppose 3050fps would be the max. Also, how far are you seating your bullets?

Re: Loads for .300WM-.300WSM

I have two loads so far, need to get some parts for my chrono so I can see how fast I'm pushing them:

Savage Model 16 300WSM 24" bbl

200gr. Barnes LRX
Winchester Brass
65.2 grains of RE-17
CCI LRM primers
OAL 2.935" (about .03-.04" jump, Barnes recommends .03-.07" jump)
.7" group at 100 yards
I like this load, I'm making this my go to hunting load, replacing my 168gr. TSX load with H4350

230gr. Berger Tactical OTM Hybrid
Winchester Brass
62.5 grains of RE-19
CCI LRM primers
OAL 2.965" (max magazine length)
.55" group at 100 yards
this load is almost 2.5 grains higher than Berger's recommended max load, I estimate this at 2650fps, which I think is good since RE-19 isn't the ideal powder for this round, I'm going to get some RE-22 and see what kind of velocity and accuracy I can get.

Re: Loads for .300WM-.300WSM

Went to the range yesterday, it was 110f when I was shooting, so some of my loads were hot. got some very interesting chrony results. I fired several loads on my 24" 300WSM with Reloader 19 and 17, with 208gr. A-MAX, 200gr. LRX, and 230gr. Berger OTM Hybrids. All loads with the same bullet were with the same specs, just different powder. Rirst up are the R-19 loads:

Win brass
CCI LRM primers
Barnes 200gr. LRX
2.910" oal (.065" from the lands)

66gr. = 2833fps average, 21 ES, .78 MOA
67gr. = 2867fps average, 16 ES, .81 MOA
68gr. = 2900fps average, blown primer, did not continue.


Remington Brass
CCI LRM Primers
208gr. Hornady A-max
2.950" OAL

66gr. = 2797fps average, 17 ES, .54 MOA
67gr. = 2815fps average, 15 ES, .51 MOA
68gr. = 2851fps average, 22 ES, .58 MOA
69gr. = 2884fps average, 20 ES, .61 MOA
These loads were all pretty accurate, but far lower than what I was expecting for this round. 69gr. gave me sticky bolts lift, so I wouldn't go any higher.

Win Brass
CCI LRM Primers
230gr. Berger OTM Hybrids
2.950" OAL

61.4gr. = 2580fps average, 45 ES, .85MOA
This was a very bad load, but I was surprised that there were no pressure signs, since I developed this load at 70f and it was already very hot; I might have to increase the charge and see where I get.

Overall, Reloader 19 was a disappointment. I was expecting higher velocities, but just could not get there without pressure signs as shown by me blowing a primer on the 200gr. LRX load. These loads were pretty accurate though, oddly consistent with most loads, maybe thats just my limitation though. Now for the reloader 17 loads:

200gr. LRX load
64.2gr. = 2980fps average, 8 ES, .52 MOA
64.7gr. = 3005fps average, 6 ES, .46 MOA
65.2gr. = 3027fps average, 12 ES, .67 MOA
All I can say is wow. Reloader 17 completely shattered the low expectations I had for this round and has made this the best hunting round I have so far. I wasn't expecting more than 2800fps since this is a very large bullet (1.624") and the load data Barnes has for the 200gr. TSX were all in the 2700fps range.

208gr. A-MAX
64gr. = 2879fps average, 4 ES, .74 MOA
65gr. = 2928fps average, 15 ES, .64 MOA
66gr. = 2968fps average, 8 ES, .53 MOA
I had a load with 67gr. but I got ever so slight pressure signs at 66gr. and decided not to continue.

Reloader 17 performed better than I could have possibly expected, especially with the Barnes round. I am kind of regretting not making some loads with R-17 and the Berger 230's, I might have to try some next time. This data just reaffirms in my mind that R-17 is THE powder for the 300WSM. What surprised me the most was the very low Extreme spreads I was getting with R-17, it was much more consistent than R-19. Also, the 200gr. LRX load with 65.2gr. was very hot when I tested it in 70F (65.5gr. gave me pressure signs), but in 110F there weren't any pressure signs, so that makes me believe that R-17 is very temp stable. I believe the very high speeds I was getting with the LRX in relation to the TSX is due to the fact that the LRX has a boat tail and the TSX does not, giving the LRX much less gliding surface and thus, much higher velocities. This load I believe is ideal for hunting anything in North America effectively, I found a round in the backstop that was perfectly expanded to .7" in size.

</div></div>

Ditto here. I would like to to know what a good starting point would be for this combo.

Here is an excerpt from RTO on page 4 using H4350:

"FN SPR 300WSM

208 Amax
WIN Brass
62.4 H4350
.010 off lands
CCI Mag Primers
2800fps
SD 5
ES 10

This stick loves the 208's .41 when I do my part. Initial ladder test was 1.25" at 100yds with 4 grain range and 20 rounds. Didnt seem to matter what was the load it just gobbled them all up."

when I went to the Hodgdon reloading center, the dispersion between H4350 and H4831 is not consistent as bullet weight increases. A 4 grain spread from starting load to max load seems reasonable, but I'm not sure where I should set my upper/lower limits.

Any help would be appreciated.

My load for the 208gr. AMAX right now is 65.3gr. of RL-17 at 2.955 OAL with Win Brass, if I use it with any other brass, I reduce by a grain. This is very accurate, only shot three 4 shot groups but the smallest was .371 with the average group being .466.

I had a load with 67gr. but I got ever so slight pressure signs at 66gr. and decided not to continue.
</div></div>

I have since adjusted my loads a bit since I did load testing. I used my LRX load with Remington brass and got some pretty severe pressure issues (two blown primers), although it didn't have any issues with Win brass, I reduced the load by a grain at 64.2gr. and made the rounds longer, now at 2.920" which made the rounds a bit more accurate, and the velocity is right around 2965fps.

My load for the 208gr. AMAX right now is 65.3gr. of RL-17 at 2.955 OAL with Win Brass, if I use it with any other brass, I reduce by a grain. This is very accurate, only shot three 4 shot groups but the smallest was .371 with the average group being .466. </div></div>

Rusty, aren't these Wizzum loads, and not WinMag?? Just clarifying. </div></div>

Yup, says so in my original post, I just didn't quote the whole thing because its very long.

Re: Loads for .300WM-.300WSM

Found my load for my SS 5R .300 win mag.
72.4 Reloader 22
FGM215M
210 Vlds
RP Brass
Seated 2.911" measured from ogive (20/1000 off lands)verified with a Hornady bullet comparator
5 shots produced a group of .174" at 100 yards
Basically was one hole. Not sure about velocity. Should be around 2875 to 2900.
Scope was NF NXS 5.5x22x56 with badger ordinance rings and 20 moa base.

Curious to see what the ES/SD is on the load.

Re: Loads for .300WM-.300WSM

For everyone what wanted some data for the WSM and 208 a-max
I shot out of a GAP templar with a 24inch bartlien. Without my rear bag I had to use my fist. All groups were under .75 moa
208 amax
2.975 oal (mag length not touching lands)
powder- H4831 not SC

I loaded 3 rounds each 62-66 grains and one round at 67 to see if it would be too hot.


62 grains- 2614, 2629, 2624
63 grains- 2666, 2660, 2661
64 grains- 2671, 2682, 2704
65 grains- 2842, 2783, 2749 best group .25 moa
66 grains- 2836, 2842, 2867
67 grains- 2962
I had no problems with pressure at all. Tomorrow I'm going to test up to 69 grains. 66-69 grains is a slightly compressed charge since I'm not using the SC powder.

Man I wish I could run a higher charge but at 73 of H1000 I'm getting .38" five shot groups and as the charge increases so do the groups. The groups did start to shrink again at 76 but that is where I stopped. I'm going to load some higher charges and see what happens. I would really like to get to 3050fps which if I did my calculations right is what is needed to stay super-sonic to 1 mile.

Re: Loads for .300WM-.300WSM

Here's some data for 208 AMAXs in .300 WM. This data is from three different trips to the range. Start from the book recommended lows and work up, as these may not necessarily act the same in your rifle. Note that I wasn't able to get H1000 to reach 2850 or above consistently with my set-up. Once I got into compressed loads, as I added H1000 from 76.0 grains to 77.2 the velocity wouldn't really pick up above about 2830. I was shooting another caliber these days with a known load so i've elminated gross error by the chrono. Didnt see much in the way of warning signs of pressure, but I figure powder isn't burning. I decided not to test higher with H1000. I'm wanting 2850, so it looks like i may have to stick with IMR 4831 to get there.

Rifle: .300 WM, Remington Action 26 inch barrel with sako extractor mod.

Cartridge dimensions: trimmed to 2.610; bullet seated to ogive on 208s at 2.820. COAL 3.555. CCI Magnum primers

Re: Loads for .300WM-.300WSM

Only one load for 185 hunting VDL for 300 win mag. Would like to see any other
Loads for this. Need ones for blind mag length. This is a Winchester model 70 synthetic 300 win and 185 VDL.

Re: Loads for .300WM-.300WSM

So far here's the best load I've found for the 300wsm Fn TSR

190 berger target vld
H4350 62.5 grains
CCI magnum primers
2.860" OAL
Win brass
3/4" at 200

Working on some loads with RL 22 and the 190s. 66.6 grains figured right at 2880 by the bullet drop from 200 to 670.

Yes, I'm loading 79.2 of the H1000, also using the 210 VLD, running just over 2900 fps in my Rem700 5R
