300gr .338 lm only please.

[bowstryder]

I am requesting load data for the above mentioned only. I am not shooting anything else in mine at this point. If you would be so kind as to what barrel length and velocity as well as accuracy I would be greatful!
I am very interested in the 27" barrel loads as this is what mine is getting (broughton 5c 9.3 tw)
Btw, I am currently in the sandbox and my rifle is being built while I am gone. I am bored on my down time and basically just need some pick me ups in the long range department. As resident firearm super freak, I have really no one to talk to about ballistics around here, as the 7.62 is "awesome" for most guys here. LOL
Thanks and God Bless.

Im partial to a 215M & 79.8gr of N165 behind the 300 Scenar in the TRG42.

This page here will provide you some good data. The 300 grainers will run about 2700, give or take 50 fps either way. Retumbo, H1000, R25 are great powders for it.

thanks guys. I have been using all the searches I could to get the average for what I am hoping to expect. Some are very descrip. some not so much. But it all helps.

From my TRG 42 (27 1/4" barrel):

Lapua brass - once fired
300 SMK
CCI 250
H1000
3.730" COAL

Shot over two chronies in line with each other (velocity listed is the average for 10 shots):

<span style="font-weight: bold">90.5 grains</span> - Chronie 1: <span style="text-decoration: underline"><span style="font-weight: bold">2774</span></span> Chronie 2: <span style="text-decoration: underline"><span style="font-weight: bold">2711</span></span>

<span style="font-weight: bold">92.0 grains</span> - Chronie 1: <span style="text-decoration: underline"><span style="font-weight: bold">2811</span></span> Chronie 2: <span style="text-decoration: underline"><span style="font-weight: bold">2753</span></span>

I'm not sure why the large difference between the two chronies when they were basically touching. Seems like one is reading a bit fast, or one is reading a bit slow, or a combo of the two. But, that's ballpark for what you can expect I suppose. Seems like depending on your specific barrel, lot of powder, conditions, etc... 2700-2800 for 300 grainers in the Lapua.

90.5 and 92.0 appeared to be two accuracy nodes from my initial load development, which is why I checked them for velocity. 92.0 is getting towards the top end but still good to go in my rifle. Work up to that on your own, obviously...

It's times like those when I am thinking that popping for the oehler is NOT a bad idea. Thanks for the info.
