300 wsm Long Range Load

[Benjblt]

I'm looking to load or have a gunsmith load a round in my 300 WSM that can shoot 800 yards. What are you all shooting with respect to bullet make and weight and powder? Just curious. I can't load my bullets off the lands as its essentially the a SAAMI spec magazine.

I run the 215 Bergers with R26.

Hornady 178 ELDX form Choice Ammo...

Thanks guys. I've been looking at the ELD-X's.. Probably leaning toward 200 grainers.

Do the Bergers blood shot the meat bad?

I would look at the 200 ELDX, the 208 ELDM, or the 212 ELDX.

I am still breaking in a new 300wsm that was built by Mike at Hells Canyon and the factory Hornady 200 gr ELDX precision hunter ammo is amazingly accurate and consistent. I wanted to do load development with the 212, but that 200 bullet is going to be hard to overlook.

Not in my experience. I've been very happy with them.

What velocity are you getting with r26 & 215’s Justin? Any temp stability issues?

My hunting load is gonna be the 181gr hammer at 2950fps over H4831SC, could chase a bit more velocity but its a flat node. Also working with the 212eldm but need to spend more time on that load. Neither are SAMMI length.

How does that Hammer stuff do? Is it that much better then Barnes?

Dunno yet, hopefully get to compare in a few weeks.

200 eldx 61.0grs of RL17 0.025” the lands. Runs 2910 out of a 24” Bartlein and 2900 out of a 24” hart. 5 shot group @ 100yards. walked it out to 1150yards with out issue.

im using 178gr eldx running at 3025fps using H4350

215 Berger 15 thou off lands, as much rl26 as your brass can stand. Bertram is the toughest, unfortunately not the most consistent.

 

[Fonkie]

What velocity are you getting with the rl26 & is it a custom chamber to seat them long?

 

[wind gypsy]

What length is your magazine?

2.86" in 300 WSM is pretty limiting. 200 ELDx have a shortish nose and would be a good place to start though. That is what I use in my 300 WSM that is limited to 2.9ish by the magazine.

Based on manufacturer explanations they're two different designs intended to do 2 different things on impact - The Hammers are supposed to fracture partially and "in a way" emulate a Berger from what I'm reading, only with COPPER fragments rather than LEAD - Someone correct me if I'm getting the wrong intended message

That's interesting. I guess that I could have read up on that. I wonder how that works if the Hammer bullet I'd be using is a lighter, say sub-180 grain, 30 cal bullet and you can't count on the weight of the bullet to carry through (literally) despite lack of weight retention. I just can't load heavy (long) bullets in my 300 WSM that has a SAAMI spec throat/chamber/mag (whatever it is). Thanks for the input.

210 Berger (because of a 1:11 twist barrel; if 1:10 twist definitely go with the 215s as the 215s have a noticeably better BC to carry more energy at longer distances and buck the wind better...) and Hodgdon 4831SC. My brother has taken several elk out to 860 yards with this load I worked up for him. For long range work, a temperature insensitive powder can be very important for consistent, repeatable velocity in different temperatures, otherwise some guys adjust powder charge with temp sensitive powders and carry ammo with different powder charges depending on the expected temperatures, but that seems like a pain. Might consider sticking with on of the Hodgdon Extreme powders or the VV 500 series powders seem to be doing well in this department from what I hear as well. Long range is all about consistently reducing/eliminating/accounting for known variables to make consistent hits. Temp sensitive powders are just one more variable and a 50+ fps difference in MV due to a temp sensitive powder is no good at 800 yds...
