230 Hybrid Target Bullet Jump

Need to hear your experiences on how much jump these bullets will put up with and still shoot very accurately. How do they react to .2 - .3" jump before engaging rifling? Thank you!

Re: 230 Hybrid Target Bullet Jump

I have loaded two 230 gr hybrid target bullets so far. One in my 300 RUM and the other my friend's 300 WSM. In both cases I just seated so the bullets would fit and feed from the magazines.

The 300 RUM has a wyatt's box mag, never bothered to figure out the jump. The 300 WSM is a Browning A-bolt and the bullet is buried in the case. (see pic) Jump with this one is around .140".

In addition to the 230 hybrids I have loaded for a 6mm-284 with 105s, and several 168s in 7mm Rem Mags. In ALL of them the mag box limited OAL. I just seated to fit and feed and they shot tight groups. None required seating depth changes.

I did seat into the rifling with the .338 300 gr hybrid in a long throated 338 RCM in a LA. Had lots of room with box mag. This was the first hybrid I tried after using VLDs for so long. I seated the bullet as one might do with a VLD as was my old habit. I'd bet that bullet would shoot with a random jump too.

I'd say just seat for magazine and give it a try. Tweak seating depth if necessary.

What kind of groups do your rifles shoot with the 230's seated this way?

Re: 230 Hybrid Target Bullet Jump

WSM three shot groups 1/2 MOA. 300 RUM three shot groups tighter around 1/4 MOA. These are at 100 yds. More importantly when shot at the steel at 500 M they hit where we aim them. Both rifles were put together for longer distance on elk. We ended up killing some with our lightweight rifles and hiking in over a mile in the deep woods where they reseeded a burn with wheat and barley.

Maybe next year we'll get to blast at distance. It all depends on if snow moves them out.

Re: 230 Hybrid Target Bullet Jump

I also seat mine just enough to fit them in the mag. My 300 ultra shoots these 1/2 MOA at 200 yards. The 400 yard gong hates this gun with these bullets

I haven't tried the 300 grain in my 338 ultra yet. Been shooting the 265 grain Barnes with awesome success.
