There are a few posts about them in the Reloading and bolt action sections. This is probably the best place for a post on them. I was lucky enough to get a bit of a preview of them last year and they're pretty damn impressive IMHO. The 230 and 250gr .30 caliber Atips are what really sold me on the idea of building my 300 PRC, and the rifle was/will be built around the bullet.

The 110's and 135's certainly have a place in PRS, especially out west where you can stretch your legs, but I almost think the potential is wasted on 300-800yd plates. I think the real benefit of how these are designed and manufactured will be seen in the 1000+ realm. Very consistent elevation from the consistent CD profiles. I'm hoping to push 1500-2000+ once I get my barrel spun up here in the coming weeks. Combined with the 4dof and doppler data I think it's a killer ELR combo.

Anyway, can't wait to start hearing some more real-world reports with them, and can't wait to get my hands on them, too.

I think it should work. I asked about it, and a 9 twist will keep them stable, but may suffer some slight drag increase/BC loss. Maybe run into issues on the Alaskan coast in the winter, but most normal temps, even at sea level should work with a 9 twist.

I’ve got 100 back ordered on Midway. We’ll see how it goes. I’m on the Texas coast so low temps are not the norm.

no 7mms sigh

ongoing debate of 300PRC versus 7/300PRC may have been made easier (sherman improved)

Pretty sure it says in the extended video. I didn't catch the 6mm (I think 1:7.7 or 1:7.5), but the 6.5's both work with 1:8 twists, 1:7.5 might be more appropriate for the 153gr. The 230gr .30 cal is 1:9, and the 250gr is 1:8.5.

Those are suggested rates. Slower rates may still work especially at higher elevation, potentially with some BC loss.

A 7mm would interest me but looking at the 6.5s, the 135 doesn't seem to offer any BC improvement over the 140 ELD-M and the 153 is barely ahead of the 147 ELD-M.

Maybe consistency is the selling point?

The .30s do sound good but the chambering, brakes and cost involved make me not want to try them.

In theory, you'd be able to drive the 135 faster than the 140, however. Even if the BCs come out the same, speed wins.

thats where the 153 confuses me besides for the 6.5 PRC/SAUM/SS/SST etc

153 over 147. 1% BC increase. 4% weight increase
140 over 135. 1% BC increase. 4% weight increase

I was looking at that but people seem to drive the 147 as fast or faster than the 140 so even if it speeds up a bit, I'm not seeing the 135 stand out too much.

I haven't watched the full videos but it would be good to see reloading data so we can see if it's worth changing away from something that is already working.

Consistency might be the thing for ELR shooting and maybe worth the price but most shooting isn't ELR...

I doubt the 153 is being aimed at the standard capacity 6.5 cartridges. The 135 seems better slotted for that, IMO, while still being able to be driven fast in a SAUM, etc.

I think that's a fair assessment. The two I'd consider for PRS are the 110 6mm and the 135 6.5mm. You can run the numbers and balance it out yourself, but the 135 offers the 140's BC, tighter spreads, and faster speeds than either the 140 or 147 with less recoil. They all work. It's which numbers/results matter to you.

Probably too slow of a twist especially only a WM

Throw it into Berger or jbm

I think the 135s will be the sweet spot for SAUM.

The 147s are great projectiles, but they can handcuff you depending on your freebore. The .081 GAP chamber is way short for the 147s and takes up a ton of case capacity unless you want to be jammed like 20+ thou.

The 135s on the other hand offer similar BC, but will be less restrictive in short lead chambers because they’re smaller. Couple that with the speed advantage, less recoil, etc. and I think you’re looking at a very promising combination.

Even more excited about those than the 153s.

I called Hornady this morning inquiring about the twist rate needed for the 250 gr .30 cal. The man said 1:8.5, therefore I will order that twist.

Once built, the best place for me to take it is Terrell county, Texas. Good friend of mine has a ranch there, that affords line of sight for +2 miles. I'll find out where these 250's peter out. DA will be between 3000' and 7000' depending on when I go. The barrel will take a few months, but I'll let yall know what I learn. In the mean time, I need to find the dang bullets!

Anyone seen these in stock yet? Or is the rumored May 18th date a high probability?

I have a few boxes of 153’s loaded up from copper creek ammo I’m going to be trying within the next few weeks
