Yes I like that powder, I just found that the 212gn lrx is for a 1/8 twist or better, my 300 whrby is a 1/10 twist.

I've been thinking about trying these at some point to, but haven't been able find any. Where'd you find yours?

I was able to pick some up at midwayusa I'm still waiting for my barrel. Can't wait to try them just might be awhile. Have bartlein on order 1:8 with the new 400modbb medal 27". Sendero

Exactly what does bore-rider mean? Any special chamber or barrel requirements? Have a new 300PRC with a 1:8 twist, would like to give these a try.

Not sure what the bore rider means. If you look at the bullet it is very long. There is not much of an area that would set in the neck. I would thing it would not need alot of free bore. In your 300prc I im thinking you might have to shoot it as a single shot. Was going to post a picture of surface area for bullet seating. Seating width is .307 just above that at .299. Was unable to load picture of what I mean. Send me your email will send a couple of pictures. I'm building an 300 norma improved.

It means there's only enough bearing surface to seat the bullet and engage the rifling, the rest of the bullet is smaller than bore diameter.
There's no way to adjust seating depth, and there will be a ton of freebore.
Overall length in a 300 PRC is around 3.9"

im338, how long is the .307 bearing surface and OAL of the bullet? Barnes shows 3.960 OAL in the PRC. Thanks

 

[Send it 284]

Here you go
The bearing surface is .290
I'm at 3.970 seated at the end of the bearing surface in a 300 prc case
The expanded bullet was recovered at 700 yards fired into loose soil

 

[slikmrc]

Impressive, looks like it was made for the PRC with 4 inch mag box. Thanks

 

[im338]

How do they shot. There isn't much info on them yet.

 

[Send it 284]

I haven't shot them enough to really know, I sold the other rifle so only put a few groups through it.
I have an 8 twist 30 nosler barrel in the works, I'll do some serious testing when I get it screwed on.
