Tyre kicking - 300prc

I’ve been planning on getting a 300wsm for a while know. I suspect there will be others out there who like me are planning for a new rifle, collecting info and ideas with the intention of making a purchase once supplies open back up.

I’m not planning on spending custom rifle sort of money but will do some minor DIY to accurise a factory rifle.

I want to shoot heavy 30cals on steel and goats past 1000m. I will be aiming for an unscoped weight of around 4kg.

The original plan was a tikka 300wsm. I have a compatible stock and also a chassis, AI mags and scope all good to go for a tikka.

With the wsm I can seat projectiles long while still mag feeding from the AI’s.

I’ve just looked into brass and I’m basically limited to Norma which has shit reviews and pricing. Tikka are also behind the ball with barrel twists.

I had paid off the 300prc as marketing hype. What I realise now however is that factory rifles will offer appropriate twist rates and I will be able to get top shelf brass.

Who has experience handloading for 300prc factory cambers? Will the likes of the browning x bolt or bergara ridge allow me to run 225gn projectiles seated appropriately?

If not, how likely is it that a smith will be able to adjust the throat on one of the above rifles? Ie will I need to source a reamer?

(I don’t mind single feeding / modifying magazines as I will likely make a new stock from scratch).

Cheers

the factory Saami reamer will be fine . the purpose of the 300prc was the long heavys it isn't handicapped at the SAAMI chamber like the Win Mag and Nosler the Bergaras look awesome id be looking hard at their carbon in 300 PRC

Thanks mate that’s reassuring to hear. A bergara barreled action would be the go if they become available

Have you considered a Howa barreled action and a KRG or MDT stock?

Have you seen @mikee 300 Norma 4 sale on here?

Yea sure have but $5000 Will be hard to justify. One day I’ll own a custom action..that rifle restocked in a manners would be dream rifle material.

Howa could be good with $ left to cerakote and part of the fun is tinkering around as well. Don’t see many Howas on this forum these days

the howas are awesome bits of kit the bergara will have more aftermarket bits and bops being a rem clone

I thought every other Forum member had a Howa in either 223 or 300BLK?

Howa 264 Win Mag

Give Mark Mc farlane at Desert guns a bell as he has experience with the calibre.


He built my mates 300 PRC and it's a tack driver albeit he built it for trophy sniping. Just pertaining to the calibre that is

@ROKTOY Yes true, howa mini actions are a different story I suppose. Still most new toys seem to be rebarrelled tikkas.

Might have to flip a coin and either run 200gn out of a tikka 300wsm or go heavy in a howa prc.

This will be a slow process anyway hopefully gather bits and pieces together by mid winter.

I'd thought of buying a Sako Carbon Wolf in 7mmRemMag and immediately rebarrelling it to a new TruFlite barrel in 300 PRC. A new Sako 7RM barrel should be fairly easy to sell ?

There’s a nice WSM Tikka in the for sale section.

dam the old 225s are going to be glong slow out of a wsm shit my old wsm struggled with the 208 to the point that the 7mm 162 was ballistically better

300 norma is a game changer ide 100% go that way for chucking the big pills mine shoots the 225eldm at 3000fps

Tis might be interesting:

Sourced lapua brass so I’m committed to the Prc for now.

Howas got the 8.5 twist which is another bonus and now drooling over a Grs hunter stock.

It would make a fairly attractive rifle for under $2k and the added weight will help keep my brain from rattling around too much.

Time will tell where this project ends up, just chipping away at one purchase at a time.

KRG don’t do howa long action chassis. Seems like a lot of companies are the same.

I’ve got a bravo for my tikka and they are they are the perfect fit for my body

The seekins ph2 sure does tick most of the boxes @Thar

I’ve timed this well it seems. Gunworks have delivered me eldms and I’ve tracked down 2225.

I put my name in the ring for the prc in the buy/sell so it’s coming together 👍

Mates 300prc throws 230g atips at 3000fps

What powder is he using? I’ve got 2225 and although it’s less than ideal I’ll also give 2213 a whirl.

That dudes reported velocity with Rl33 doesn’t seem right to me..

Here’s some data for RL25. There is not really anything on any of the forums. There is also nothing in GRT.

Hornady has this as the highest velocity for the 225eldm maxing out at 2850fps.

I used Fiocchi LR primers due to availability. This may explain the results but I’m surprised to have had to go way over book max and not even get close to their speeds.

RL25
Lapua virgin brass
Fiocchi LR primers
COAL: 3.68”
24” barrel (new)
13C
Magneto speed ( verified with a proven load )

73gn 2441
73.5 2475
74 2517
74.5 2512
75 2544
75.5 2573
76 22576
76.5 2594
77 2606 (book max - claimed 2850 using fed 215s)
77.5 2630
78 2649
78.5 2646
79 2693
79.5 2718
80 2736 - ejector stamp

I will try another powder and if need be can revisit 76.5 - 78.5 which all grouped together with a 55fps spread over 2grains. I keep telling myself I don’t need the speed but a loss of 200fps is a lot.

I would have thought magnum primers would only have assisted in consistency not velocity as Fiocchi use these in all their magnum loads.

If you never had it in the first place, is it really a loss?

If it's any use. I'm using 76.5gr 2217 with the 230gr hybrid @ 2850fps

Yea not really a loss just hard to except your junk is smaller than everyone else’s sometimes…

Thanks Lau Lau that’s what I was expecting to get, will be picking up some adi powder in a few weeks.

Will also try N570 if I find someone to trade with.

You can and don’t ask me how gain a lot of speed with primer choice want me to send you some 215?

Nate runs rl26 in his 300prc, I rum rl33 in my norma
Rl33 doesn't shoot great in the prc

You might get better results with 1 x fired brass as well.

In my experience the fireformed brass performs marginally better, and once the barrel has settled down you can get another 20-50 fps.

YMMV
