Home Forums Reloading Big Game Rifles 270WSM

All of the powders you have on hand will work, my first grabs would be 4350 and MRP for the bullet weight stated. My two 270WSMs do quite well with both R17 and H or IMR 4350 with 130-140 pills.

I'm running 130TTSX at 3265fps ahead of IMR 4350 in my 23" m700 and 130NPTs at 3230 ahead of R17 in my T3. The 130 Partition at 3200+ is flat wicked on deer size game. The TTSX works great as well and will penetrate crazy good, but for deer size game, I like the larger wound channels of the Partition.

I'm going to run the 130 TBTs in the T3 next year just to see how they compare to the NPTs. The TBT is definitely a more sexy pill and I will say I'm partial to tipped pills. Between flattened tips in the mag and chewed up tips from loading/unloading, the change will be welcome. I still love NPTs, but I'm reminded of the reason I got away from exposed lead tipped pills years ago.

Good luck with the new rig.

elkaddict,

I load my .270 WSM with RL22 powder and the 130 gr. Nosler E-Tip for 3300 fps out of my 24" barrelled custom Vanguard. This load is very accurate, and works great on deer- last two I shot with it were both over 300 yds, both pass-throughs and dead deer. The E-Tip has given me better accuracy than the Barnes TTSX, Accubond, or Accubond LR bullets. I believe .270 and 130 gr. bullets were made for each other!

I finally found a low wind day to shoot loads I’d worked up with H1000 and RL 26. Seated to max length for the Tikka mag, accuracy was in the 2” range for both powders. I was a bit surprised to see the nosler recipes showing pressure signs with book loads given the longer throat. I’ll play around with IMR 4350 and 7828 next. If those don’t shoot, I’ll drop down to 130 Partitions. Interesting, my Tikka in 270win wouldn’t shoot accubonds well either but 130 Partitions and Interlocks shot really well. Chrono battery was dead but I will say the 140 Accubonds appeared to be smacking my 300yd gong every bit has hard as my 7STW with 160 Accubonds and notably harder than the 30-06 with 165s. I’m hoping I can get it to shoot.

Any pattern to the groups you were shooting? They may want to be seated shorter. H1000 and 26 are pretty danged good in the few WSM's I have worked with. 7828 is another that worked really well in the past for me as well.

No real patterns at all.

In my Tikka, I shoot the 130 NBT for my WT load. For tougher game, I switch to the 130 NAB. Virtually the same POI with 63 grains of IMR4350 at 3250 FPS. NBTs shoot sub-1/2 MOA. NABs are sub-3/4 MOA. I'll have to verify COAL.

This is typical result. Ram was 370 yards. Fast forward to around 1:01 to miss all the fluff...

130 nosler ballistic tip, 60 grains of h4350, work up to your comfort level

I am getting 3200 fps almost on the nose with a max charge of either R25 or R26 at 69 grs. for each. I am not sure which is more accurate as I stopped testing them when each consistently shot under an inch. R22 & MRP worked well too but about 50-75 fos slower. I think I will go to R26 completely for the improved temperature stability. The same load has worked with Interbonds and the TSX. I arbitrarily started with 140s and see no reason to change but the 130s are speedier. In my rifle seating to the cannelure or for mag length the bullets have a fair amount of jump even though there is hardly any throat on the chamber.

I used Retumbo with 215 Mag primers and 140gr Accubonds. Great loads / bullet combo - loved it. I had 2 Tikka T3 LS rifles in 270WSM. One rifle liked close to 69 grains, the other 71 if I remember correctly. Sold both to my inlaws and bought one in a mint Sako m75ss.

Had 7828SSC but never tried it as I was very happy with the results from Retumbo powder.

Go buy some mag pro and don't look back!

I’ve used Magpro, 7828, RL22, RL25, RL26, Retumbo and probably some others I’m forgetting. It has done excellent with all of them. I’d try pushing those ETips pretty deep before giving up on them. I haven’t seen the 270 WSM as a hard cartridge to find great loads with.

MagPro was the ticket for mine. All loads with R-22 grouped 1.25"-1.5". Switched to MagPro and the groups just kept getting tighter. Nosler book max of 72g shoots into just under 0.5" to 0.75" depending on me.
