.270wsm 130gr e-tip

[SR80]

I picked up some 130gr etips for my 270wsm the other day to try. Loaded them .100 from the rifling, best group was at the mid load (63gr) RL-22, with two touching and one to the right about 1/2 inch. Now usually I would would load a few more, and make a 63.5, and 64.0gr and try those to see if the group tightened up. But that will bring me above the "midload" or "max" listed for an etip. This is my first try with etips, my question for you experienced etip users, should I carry on and watch for pressure signs? Maybe even in 0.3 increments or play around with the seating depth with the 63gr load? Thanks.

I would think the 63gr load with RL22 would be pretty stiff already. I load 66gr's of RL22 with 150's BT's and that is a shooting load. I would put them across a chrono and see what kind of speed you are getting. That would be the best indicator of if you need or can push a little faster. Scotty

Thanks, im going to arrange to borrow my buddies crony this weekend.

Here's my recipe for the 130ET for my 270WSM (Mod 70)

Powder: IMR4350 - 60.5gn
Primer: GM215M
Brass: Win nickle trimmed to 2.09"
COL: 2.880"

Avg velocity is 3350fps

Wow, Rich, that load is smoking! I can't imagine much walking away from one of those. 270 Win's are weeping at that kinda load! Scotty

Thanks for the reply. How far off the lands are you ?

I wish I could remember. I do know it IS closer to the lands than the 140AB load which is at 2.875".

Ya i was gonna say it must be pretty close to the lands, I think in my mod 70 with the etips 2.876ish is touching the lands, and .100 from is 2.776. I had a 1inch group with 63gr rl-22 and 2.776. i made two more batches, one at .050 and one at .075 from the lands just to see how they do. Just have to wait for the weather to cooperate, the road to the range apparently washed out and its closed for now. I hope to find a good load with the etips, I wanna use them for a bear this spring.

SR80,

You are on the right track, stay at the charge weight and adjust the COL.
If the .050" and .075" loads don't shoot better, try seating a little beeper than the .100".

Let us know how these loads shoot for you.

I will for sure let you guys know how it goes. I have a crony now too. But it looks like itll be 2 friggin weeks before i get to the range, hopefully sooner though.

 

[SR80]

so i made it to the range last night finally to test some more etip loads. i had two batches of 63gr RL-22, seated at .050 and .075 thou from the rifling. groups were not good, and the velocity was just over 3000fps.

I did pick up from RL-17 though, and had a few batches made with 140gr AB, velocity was bettter, anywhere from 3100-3250 fps. groups were between 1-1 3/4 inches. So it looks like this might be a good powder for my gun, i have more tweaking to do still though.

I am also going to try the etips with the RL-17. I cant remember what nosler recommends, start 2 grains below max? Or would that be my max? All i have is info from alliants website which says max load of RL-17 for a 130gr is 62grains. thanks.

 

[DrMike]

The Nosler recommendation is to go no more than 2 grains below maximum charge as the maximum for the E-Tip. Be cautious using the Alliant data as that is generated for a cup-and-core bullet. The E-Tip is a monolithic bullet. Consequently, it is considerably longer than either the Speer BTSP or the Speer SP, and has a significantly different bearing surface. I can assure you that if you use the Alliant data, you will be overpressure.

 

[SR80]

Thanks Dr.Mike. I was planning on starting lower than that with the etips. How much RL-17 are you using in your 270wsm with the etips? I was looking through old posts trying to find it, but couldn't. thanks

 

[DrMike]

I'm using 59.5 grains of RL17 with the 130 grain E-Tip. This should be considered as a maximum charge. It generates ~3250 fps for me in my Model 70. It is safe in my rifle, but, as always, work up from a safe minimum in your rifle.

 

[SR80]

thanks, will do

 

[SR80]

well i tried out more etips, nothing promising yet. The 140 AB seem to be shooting better, and with more velocity. So i think they will be my go to bullet this spring.

 

[DrMike]

There is nothing wrong with the 140 grain AB from the 270 WSM. I have loaded it several times with good success, especially when using RL19.

 

[SR80]

ya I like the accubonds. Im having great results with RL-17

 

[Mighty Peace]

I have not tried the Etips, but the 140gr Accubonds are my choice of bullet for my two Tikka T3 LS 270WSM rifles. One likes 69.0gr of Retumbo the other 71.0gr COMPRESSED LOAD. Federal 215 primers in Winchester nickel plated brass. Getting 3260-3300 ft/s with groups under 0.5" @ 100 metres. Cant remember the seating depth (reloading diary at home) but you can only pass a single sheet of printer paper between the inside edge of the magazine and the bullet tip.

Taken elk, moose, bears, mulies and whitetails and the odd coyote and wolf at various distances. I LOVE THIS CALIBER AND BULLET COMBO !!! VERY IMPRESSED !!!
