I’ve had great luck while breaking in a barrel is swab after each shot for the first 20 rounds, clean out all the copper with sweets 762 and go from there. Make sure you get all the sweets out or you will do damage. My prairie dog rifles were broke in that way and they are all one moa shooters
I agree. When I was looking at the 307 I couldn't find real information just advertisements that were supposed to be reviews. I am going to do a follow-up with more and more actual range time.
Thanks for the .280AI series. My favorite cartridge as I have 2 rifles chambered in .280AI. I’m considering possibly a 7mm-08 in a 307. The Mark V Hunter was tempting but I passed. Interesting that it likes the 140’s. Thanks again and keep us posted on the rifle as you put more rounds down range.
A shooting tip that I learned from the old days in my k3/5 first marine division scout sniper platoon is to hang onto the gun with both hands just like you do when shooting offhand and put the front shooting bag on the fore end of your stock with your left hand behind the bag and it makes the gun sit on a perfectly still platform for precision shooting. Please try this one little shooting tip next time you go to the gunrange, and don't shoot until you breathe all the way out, also known as respiratory pause. You won't be thinking about breathing instead of the perfect sight picture when you touch off your shot.
I'm in Worland and I sure wish I was closer to take in some of your knowledge hands on. I found your channel after seeing your review on the Weatherby website. Id love to see a video about your elk hunt with it. Do you have other weatherby's as well? I have a number of them, and am a big fan.
After a bit of fine tuning on my load it has settled in at under an inch at 100+ yards and under 1.5" at 200 yards. It likes the Nosler Accubond 165's. Let me know how you like the 270 in the 307.
Hey Jim. I am a 70+ yr old subscriber and really enjoy your videos. I've been interested in getting or building a 280ai. This rifle looks intetesting but don't like AICS mags for hunting. Maybe I can find a 3 rounder. Has the accuracy improved with yours after 7 months? Thanks again for the very informative videos. Barry
Hey Barry, thank you for the kind words and subscribing. The rifle has really came into its own as far as accuracy and function. I plan on doing a range session with it in a week or so to share on the channel. I will get it out next week and see if a standard Remington (BDL) bottom metal will work with the Weatherby stock and let you know. I suspect it will.
Nice series. Id try 55-56 H4831sc for 160s. I got 175 ABLR to shoot moa near max charge of 7828. Interested in the 307 or a Rem 700 Alpha 1. Good options nowadays.
I've been working on loads. Back and forth on powders. Landed on 55grs IMR4350 CCI200 Peterson Brass 160 gr partition under a inch at 100 several times. The more I shoot it the better the accuracy seems to be getting. The 160gr Accubond shoots just as well as the partition. Hunting the rest of this week.
I just download my 1975 7mm Remington magnum BDL to 280 AI level and use the 139 gr Hornady interlock bullets. That old gun ALWAYS pokes all three rounds into a single jagged hole at 110 yards. I'll just stick with what I have. I use IMR 4831 powder and Remington brass that is neck sized only, meaning that I back off the resizing die one Quarter of a turn from touching the die. Believe it or not, you will have a perfectly formed brass for your individual rifle.
I agree. I only neck size after fireforming. I bought some 280AI brass and loaded them, fired them, and only neck sizing from that point forward. One of my favorite characteristics of the AI cartridge is the stability of the brass.
You might try the Barnes TTSX 168 gr. bullets with Ramshot Big Game powder. They shoot well under 1 inch in my 1:8 twist .280AI barrel and chronograph 2800+ fps. I had complete pass-throughs and impressive performance on kudu and bushbuck in Africa last month.
@JimmyChrisawn They are very easy to get accuracy out of in my experience, and they make a pretty devastating wound channel for a mono or any bullet really. Expensive though.
It is built at their Sheridan Wyoming facility. The action seems to be a sourced action, but I don't believe it is a Howa. They are selling the actions for those wanting to build a custom rifle. The action is made in the USA
@@JimmyChrisawn the actions are inscribed “designed and tested in Sheridan WY”. It’s hard to believe they’re only $1199 with that kind of fluting, trigger tech triggers, pic rail, nice stock shape, mag bottom metal, and USA built barrels and actions. Those features on Bergara, Christiansen and Springfield are around $1900-2k. Something is amiss and not one reviewer has mentioned where it’s all made as in other bolt gun reviews. No biggie but would be nice to know
Have a look at this podcast. It might give you some better answers. I'm digging into it a bit deeper and may make a follow-up video. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-rrWSSPTZ728.html
I am look at this rifle in 280AI. And Browning xbolt 280AI. And the kimber pro hunter 280AI. I like the looks of the 307 except for the big magazine. Do they make a smaller magazine for it?
It takes a standard AICS magazine. You can get a three round magazine (to replace the 5). The Kimber is a fine rifle but has a very lightweight barrel. It starts being inconsistent after three rounds. Here is a link to the 3 round magazine. Hope this answers your question and helps.

@JimmyChrisawn thanks i do like that alot better. I do like Weatherby mark 5 hunter 280AI badlands to. Mark 5 has the 1@9 twist. Browning has a 1@8 twist. Going to start out with a hornady eld x 162gr and go up to a 175gr in different brands. I have several boxes of Berger 168gr VLD hunting bullets.
The 307 is 1/9. Mine likes 160 Nosler Acubond and Partition, and the 168 Berger. I found it took about 50 rounds to see it come into is own for accuracy. But with all three and IMR4350 it is 1/2" at 100 yards easy. I haven't tried anything heavier yet but want to try some hammer bullets. Let me know which one you end up with.
Trapper, Graf and Sons usually have 280AI Peterson brass in stock and sometimes so does Midsouth Shooters Supply. Midsouth sometimes has primed 280AI brass and both are head stamped 280AI, just FYI www.midsouthshooterssupply.com/item/0011510175/280-remington-ackley-improved-unprimed-rifle-brass-50-count
@@JimmyChrisawn i have been buying once fired brass. Nosler 280AI once fired 100 ct for 100.00. I am going to try the Hornady 162gr eld x. Berger 168gr vld. Classic 150gr and 175gr. Nosler 150gr and 175 ab.
Weatherby doesn't, at least that I am aware of, however, it is a Remington 700 clone action fitment wise (except for scope ring bases) so any 700 Remington stock for the proper length of action will work.
