Finally tried out my new rifle today.I broke it in with some loads and was pleased with the 56grain/140grainTSX/ Vit 160 load.Here is A pic[URL= ]56grain/VV160/140grMolyTSX[/URL]Here is a group with 59grs of VV560[URL= ]59grs VV560[/URL]Itried R22 and the groups were too large.Since it liked VV160 I tried it with 130 grs TSX and got these results[URL= ]59grsVV160/130grTSX[/URL]

I used Norma Cases (got them from the US at triple the price) and fed 215M primers.I will shoot this same load in Winchester cases next week and see how it compares(load in the top pic).

If you like Vihtavuori powder and the 140 gr bullet in the .270WSM, consider trying N-165 with the Nosler 140 gr Accubond with either Federal 210 (standard) primers, or Winchester Large Rifle Magnum primers. Work up gradually, and if you can get to 65.0 gr without pressure signs, I predict you will have even better results than your current load. (I can vouch for my Mod. 70 Black Shadow, anyway)

Thanks for the advice 2ndtimer.Here are todays results.I might add that I discovered that not all barrels fire molly-coated bullets accurate without some rds down the bore.I have not had this problem or not to this degree before.This might be the problem with the large groups I've been getting with my 300RUM,and 30-06.I am going to go back to testing the 300RUM with the mollied TSX bullets and see if this is the problem.The first group is with 62 grains of vit 160 and produces near 3100 fps (140gr molly bullet).The second group is with 61.5 grains of vit 560 and produces 2800fps.The last is with 64 grains of R22 and gives 2800fps.I hope to get tighter groups next week when I partially resize the fireformed cases as they are to tight to chamber otherwise.[URL= ]vit160[/URL][URL= ]R22[/URL][URL= ]vit560[/URL]

I decided to see how many molly rds the 270wsm needed to have down the bore before it would group well and the answer is one.I increased the load to 63.5 grains of vit 160 and got an ejector mark on a case with a sticky bolt lift.The load clocked at 3115fps.Below is a four shot group with the bottom hole being one of two that was used to molly the bore.The second image is what happens when you keep on fireing and don't clean the bore.It is the same load fired right after the first group.the group opened up supporting my argument on previous threads about the importance of shooting with a clean bore.BTW,I tried a few rds to settle my 300RUM and it proved to have no effect in reducing the poor group sizes.[URL= ]RESIZED CASES,63.5 VIT 160[/URL][URL= ]fouled bore[/URL][URL= ]rifle[/URL]

I use 140gr Accubonds in my two Tikka T3 LS 270WSM (wife's & mine). One rifle uses 70.0gr of Retumbo and the other is 71.0gr Compressed. Both rifles shoot close or just under 1/2" @ 100metres. I have some TSX 140 gr bullets but the Accubonds's prformance at the range and on big game have been superior.

These are very poor groups.

I suspect that you are cleaning your rifle far too much.

140 Gr Nosler Accubond, Magpro powder, Federal 215 primers = .25 MOA and 3150 fps in my Savage .270 WSM. Magpro is made for the WSM calibers try it, just don't push the velocity to the max. One other thing, most .270 WSM seem to like the bullet at least .050" back from the lands.

Going to copy a sugested loads for barmes tsx's that I had gotten somewhere,might give you some help on loads.I used the 130 tsx on a hog hunt a couple years ago,shot it in the throat at 150 yds the tsx worked great.If you use the loads for a 130 tsx pay attention to the primers they use.I tried the wlrm primer but the wlr worked the best toget smaller groups.I used 66.5 grs of IMR 4831,wlr,win brass,col 2.860,3287fps out of a browning stalker.
The load I use for deer in the 270wsm is 63 grs of IMR 4831,it is not max load only 3000Fps but it turns the 135gr sierra into one heck of a deer bullet,wlrm primes,win brass,col 2.860.Shot a doe at 150 yds,it went straight down,there was another one standing next to it,shot it and it fell right on top of the first one so I allready had them stacked up.

Target working up load for 130 tsx.

this is with my Savage 110 E R Shaw 26" barrel
IMR 7828-66 grains
135 Smk's
3200 FPS
4 shots less than .5 group @ 100 yds.

OK how do you post picture?

Here is a group at 200yds with the following load,140gr molly TSX,70.5 gr Magpro,Win cases Fed 215 primers.[URL= ]a[/URL] This is a group with the same load except with Norma cases.[URL= ]b[/URL]

I thought any beginner could shoot 1/2" groups with any factory rifle.........


Your second group was most likely shot in a strong crosswind. You should try it again in calm conditions.

270 WSM's can shoot:



WW cases, 200yds, rounds Bersin'ed to less than .0012 runout..................DJ

I can't see any load there that would excite me much, unless you're shooting at 300.

I've seen some guns take 6-9 shots before settling down and shooting with coated bullets. Once they are there the accuracy doesn't just fall off in the next group or two...you should be able to shoot much more than that.
Personally I'd get off the "molly" kick. I think after a few years it's fallen out of favor with most shooters. It never did anything for accuracy in any of my guns.
It seems from your reports that you depend on ONE group of this recipe or that to decide if the recipe is good or bad and then move on to something different. You can get lucky doing that but finding something really good will be just that.....lucky. And one good group certainly doesn't mean you have an excellent load till it's been repeated consistantly a few times. RE the group with horizontal stringing...that is something I often see when the brass is tight in the chamber....IE it takes some extra bolt pressure to close the bolt because the brass has been partially (not enough resized). OR...maybe you just shot a bad group at that time. Good luck with your future load development.

The problem could be coming from the rifle stock.This stock is very light and can be twisted or flexed with the hand.

Last fall I was at the range and a guy showed up with a new win with synthetic stock. Not sure of the model...it was a 270 wsm. He had some factory ammo. He proceded to start shooting and zeroing his scope. He chased his crosshairs for a while without any really good groups. Then towards the end of the box of ammo he started shooting pretty good. Maybe he wasn't used to that much gun and had to settle down. Anyhow in the end the gun was shooting 1-1.25" at 200 yds. We ran it over my chrono and although I can't remember what wt bullet he was shooting I do remember that it was fast enough that I scratched my head thinking he was pretty much matching my 270 wby reloads. When he first started I thought....poor guy bought a winchester....when he finished I said....wow you got a great gun. Maybe he did a 20 shot break in....maybe he didn't do a good job of getting the factory grease out of the barrel before coming to the range.....I just don't know but I do know when he was done he was a pretty happy puppy with his gun.

I can't figure out why the groups opened up with the Norma cases.The above groups with Vit 160 went from 1 inch to 7 inches.Magpro and Win cases brought the groups back down to an inch plus.I checked up a bit on Magpro and although Barnes lists it as its most accurate powder with the 140 TSX,Acurate Arms descibes it more as a magnum powder.or a powder that gives the highest velocity with lowest pressure.There are three more powders that I want to try,AA3100,AA4350,H4350.I hope the throat holds out for more because it has eroded to some degree already.STAY TUNED!
