Hornady's 300 PRC.
 

The fellas at Hornady just released the 300 PRC AND it is basically a 300-375 ruger. They are releasing factory offerings with heavy 200 plus grain projectiles. Real cool, but I would rather have a 338 or 35 on the ruger case.

Oh I’m sure the 338 isn’t far behind
Not sure of the advantage over a 300 win or a 30 nosler

Shorter action so you should be able to seat the bullets out to the lands. On my tikkas, no matter what bullet I use I’m limited to seating to 3.340” so they fit the mag.

I dont think we will ever see great gains with new cartridges. I think these new cartridges are just refined versions of what is out there. NO belt, or short neck. Long bullets in standard length mags.

It looks like the 300 PRC was designed to gain market share form the 300 Norma in the ELR game. Like the 300 Norma it is throated to run the 215 & 230 Berger Hybrid bullets and will likely get near the same performance with about 7 grains less powder. It will likely be a great hunting round with the 212 ELDX in factory rounds as well. See this linked article: https://www.ballisticmag.com/2018/10...ge-first-look/

The 300 Win Mag is not designed to run the modern bullets with the bearing surface ahead of the neck/shoulder junction. It would appear that the 30 Nosler may come up short in this department as well as it has the same throat but runs 0.110" FB compared to 0.2338" on the 300 PRC.

Hate to break it to you but your tikkas are designed to shoot blue box federal ammo. They are the discount, budget line of the sako family. The new 300 prc overall length is 3.700” so it probably won’t be offered in the Tikka line since they would have design a new plastic mag then.

All is see is a 300 win that is beltless, different shoulder angle and longer neck.

I understand that the 300 win is an ancient old design. And this definitely has some improvements. But is it enough? Too me it’s another marketing gimmick. I’m a sucker for marketing gimmicks but even I can’t see the value in switching? 300 win you can find in anywhere.

Just another 300 magnum, when we already have more than we need.

http://http://site-media.net/gunwerk...article(1).pdfThere are always the people who cannot see the benefit of advancement in technology . There have been a lot of cartridges designed without taking Length to the Lands versus Magazine Length into account. The result has been bullets with very long jump to the lands or bullets jambed down into the powder column. The Links provided above explain the benefits of cartridge design that rule this out and take advantage of the new LR bullets and advancements in powder. It is becoming more and more evident that these 21 century designs, some based on Newtons designs of over 100 years ago, are much more efficient which leads to greater accuracy and much less powder required to do the job.

We have Berger to thank for beginning the bullet revolution and can be thankful that Nosler and Hornady have taken up the challenge with their LRAB and ELD bullets. Lapua and Hornady have been the leaders in modern Cartridge design with Hornady taking the lead with the 6.5 Creedmore and 6.5PRC and now the 300 PRC. They did listen when GAP Percision suggested building the 6.5 PRC on the RCM case, which I had already done with the 6.5 EXTREME in 2009. Gunwerks came up with 7mm LRM, based on the 375 Ruger shortened to 7mm Rem Mag capacity with a neck exactly like the 28 EXTREME that I designed, with a neck designed to run both the 168 and 180 Berger VlD's seated in the. One could say that they are not an improvement over the venerable 7mm Rem mag and STW but neither are throated right for other than the 168 Berger and 150 LRAB. Link to 7mm LRM article: http://site-media.net/gunwerks/7LRMarticle(1).pdf


Here is a picture of the STW with the 180 Berger Hybrid seated just off the lands. You can see that it will not even fit in a Wyatt extended magazine when seated to the lands. Seated to Saami OAL length the bullet is way down in the powder column.

Here it is compared to the 28 Extreme and 7mmLRM with the 180 Berger Hybrid seated. Velocity's of the other two cartridges are very similar with correspondingly smaller powder charges and they will fit in a standard 3.6" Magazine with no problem..

Hopefully Hornady will borrow my 7mm PRC design. I found that it will hold about 60.5+ grains of RL 26 should match the performance of the 7mm SAUM ladder test with the 180 Hybrid. I have a 270 Precision Hunter Cartridge (PHC) that I an doing on the PRC case that is optimized for the 145 ELD-X and the 150 LRAB but that is another story.

Think I will keep my 300 Win Mag. Built it with a custom reamer. Launches 215's right at 3000 fps with H1000. Just barely fits in a Wyatt extended box, and I mean barely. Be interesting to see how the marketing team hypes this up.

I agree as you are just behind the 300 Lapua which runs only 3055 with 86 grains of H 1000 in a 26" barrel. You are likely running less than 80 grains to get to 3000 fps in your custom 300 Win Mag. I believe Hornady could have done better with a design based on the 28 EXTREME or 7mm LRM which would hold just a bit more or a bit less powder than your custom. The longer neck would allow shorter bullets to be seated to the lands and still be seated with bearing surface ahead of the Neck/Shoulder junction. An adjustment in throat angle and freebore may be necessary as well. As you can see either design would fit in a Standard 3.6" Magnum/30-06 Length Magazine. I see that I did not open up the neck properly on the EXTREME design when I re-drew it but it would be just like the LRM neck.

The problem with the 7LRM is the only brass available for it is Gunwerks and it is priced about the same as 338 Lapua. In my 7LRM with 31” barrel I’m getting 3150 with a 180 match hybrid Berger and 70gr H1000. Any more than 70gr and primer pockets start to get loose.

And the 7lrm brass was made for gunwerks by hornady. They are doing their own brass now but don’t have the 7lrm listed on their website yet. I like the advancements that the 300 prc brings but you can buy 300 win ammo anywhere on the planet. Good luck finding the 300 prc on a shelf in bishkek. If you reload and don’t take your rifle on a hunt that involves a commercial flight it could be Adventagous. I’m not rushing out to be the guinea pig with this one

Iclund you are correct. I’m running 79 gr H1000. Under half MOA load that really takes the 300 Win Mag to the next level in my opinion.

When Hornady 300 PRC becomes available you may be able to form brass for the 7 LRM with your dies however the shoulder will have to be moved almost 0.160" which may be a stretch. I had no problem moving the shoulder back 0.080" on 300 RCM brass to form 6.5PRC brass with Hornadys Match Grade Dies.

There is nothing wrong with running the 180 Berger Hybrid at 3150 with 70.0 grains of H 1000.I was hoping to get 3050 -3100 with my 28EXTREME and the 180 VLD running about 75 grains of Retumbo. Unfortunately RPS International never got this cartridge up and running but looks like I was in the ballpark with my estimations. The 180 Hybrid has a much shorter bearing surface, like the 168VLD, and should have done about the same as you are getting with the 7LRM. It is great to see that Gunwerks have taken a very similarly designed cartridge to the point that they have and proven that my estimations were close.

I have reamers for and built several of both the 7-375 ruger and 338-375 ruger. Hornady hit a home run with the 375 ruger case, I think it is probably the perfect long action case. Both the 338 and 7mm are more efficient in powder burn than any other case that I have run in quickload. We have managed to launch 250g scenars at 3140 with no signs of pressure from a 27" barrel. The 7mm will launch 180 grain bullets at faster than I care to post due to the flaming I am sure to receive (blows the doors off a 7LRM). The 300 PRC will be an amazing, powder efficient cartridge that gets just about everything right on day one. And if its anything like the 7mm for some reason the recoil seems way to light for what the cartridge is doing. It should make for nice brass for forming the 7 and 338 as well.

The 30 cal magnum world is pretty full these days, but its always nice to see new cartrages show up on the seen.

2 of my long time favourites were the trusty 300 Weatherby Mag and the standard 300 Win,,, both have proven track records and an abundance of readily available brass.

Fairly moderate on powder to get that lead down range, pretty sure that they will be around for a few more years.
