KABOOM

Very nice ride! IMHO the best looking car of that era. The modern version is a wonder as well. I cant afford it but my admiration of them is boundless.

The P14 contracts to US arms makers inspired our P17 that was produced faster than Springfield or Rock Island Armory could manage with the 1903 Springfield. Our Army had far greater numbers of the P-!7 than Springfields in France during WW1. The USMC never used the P-17. After the war the P-17 was relegated to war reserve and reissued to reserve and national guard units and pow camp guards during WW2. Art Alphin of A-square fame and misfortune used these actions as the basis for his line of African cartridges the "Hannibal" action. A fine rifle that I enjoy shooting the one flaw is the lack of windage adjustment in the rear sight. A rebuild was undertaken between the wars resulting in some with 2 groove barrels, others with 4 and 5 groove barrels. These were also the basis for the Model 30 Remington rifle produced after WW1.Some do not like the cock on closure action , I feel its a lack of shooter adaptation once you get the manipulations right imo you don't really notice the difference while shooting.

Very nice! that is a USGI 1907 sling im fairly sure that stock came from the US 1917 as I don't see where the volley sight would be. Never seen one with that sight before with that price it should sell fast. I had a P14 and after a year of not shooting it I sold it.

My thoughts are some barrels simply require some fouling to maintain zero, others do not. As for shooter warm up the 2 min prep time we had in the USMC was sufficient to adjust the body and establish the natural point of aim. Having shot NRA junior small bore in my youth I soon learned a clean bore required several sighters to re establish zero. Breath and trigger control are always important and dry fire practice is a very good tool. Calling and plotting shots will teach volumes recording sighting changes and conditions as well. Will heat change the poi?, possibly I think only if the assembly isn't square (thread mating) I haven't seen changes in impact while hot or at least enough to matter. As other have said consistency in cheek weld is important, follow through after the shot and not disturbing your shooting position between shots for any reason. Best wishes for good shooting.

My solution to the unknown number of firings is brass bucket and sold to a recycler as scrap. I am in full agreement with new brass. other members made a few points I was going to so I wont be verbose. Best wishes for good loading and shooting.

Yes ammonia based as is Montana Extreme 50BMG copper killer, I use both with zero issues. However when I finally run out Bore Tech is my choice. My sole reason to change is the smell of Sweets and Montana Extreme. Would firing strip rust and make pitting? I wonder, my natural skeptic is engaged on that idea. Never have fired a shot through a rusted bore seemed a poor idea, and the one rusted bore that was purchased by a friend we cleaned with extreme vigor to remove the "furry rust coat" before firing. This was a Swedish Mauser M-94 infantry model likely shot with corrosive ammo and ignored before we rescued it from a pawn shop, zero pitting in that bore and I cant explain why not. This is one topic that makes my brain itch. My barrels are Savage, Shilen, Ruger, Husqvarna, Brno, CZ, Rock Island, Eddystone, Springfield (USG version) Smith Corona. None of these pitted after Sweets or Montana Extreme, I don't think the barrel steel differs a huge amount and one of these bores was pre pitted from corrosive GI Ball in service. Best wishes for good shooting.

I have used Sweets for years and zero pitting or other issues, I am extremely careful to purge the bore of it before storing the rifle. Mostly I use what ever gun oil at hand to purge the Sweets. If possible I flood the bore with a saturated swab then patches with yet more oil. Probably doe this for 20 mins to ensure all residue is gone , hope this helps.

Having investigated the costs involved this project wont happen unless the donor rifle comes at a very low price point. RugerNo1 tend to be expensive and not found often in the used market my desire for one with a shot out bore is probably unobtainium.

My thought was on corrosive primers but no, so perhaps a few patches of JB Compound and see what happens. If they warranty this great. Best wishes for good shooting.

Welcome always good to see a new member.

Sir I admire the work you have done. Never in my wildest thoughts would I consider this I do hope it results in better ammo and groups. Once again you give me pause to ponder the science involved. My thought is you may be able to improve a consistent pressure while seating. Best wishes for good shooting.

I think running a few shots over a chronograph is in order. Perhaps MagTech was doing some creative B.C (BS). Perhaps create a range card by shooting at assorted distance recording elevation changes and drop. Best wishes for good shooting.

Glad things are working out! My worst error was using data with one bullet and I used another with about twice the bearing surface. At 32 degrees F it was ok the velocity was high enough to make me smile and I should have realized things were amiss. Sadly I didn't until summer. Stiff bolt lift, very flat primers made me look at things closer. After that shoot I disposed of all that brass and reworked the load with new brass and much less powder. Nosler developed data with the same bullet and powder yet even less powder, Im ok with that they have pressure testing ability I don't so I will use proven data from them. I have yet to blow a primer I hope I never do. The variables in dimensions, case capacity and lot to lot changes with powder make me very skeptical of things like Quik Load and any other calculated un shot data. After re reading your total posts about this situation I think your def on the right track. Learning happens some times easy and harmless and others its HOLY BLEEP lets not do that again. Best wishes for good shooting.

70776psi!! wow almost a proof load , That requires backing off the powder !Does the published data show this charge weight? Do you weigh each charge? Mixed cases can cause trouble, I would rework the whole load for safety.

I have and love my Savage 17HMR, but if you don't like the feel buy what feels good at that price point. Best wishes for good shooting.

Sounds like the extractor, seen this in M-9 pistols and some rimfires. Tight stiff bolt lift is a sizing issue or pressure or both. How do the cartridges feed and bolt closure before firing? Stiff then probably sizing, I like a crush fit bolt closure. I have one chamber that insists I fl all the way so I do. Does factory ammo do this as well? My single shot Ruger No1's I try to chamber with a slight effort, and if I got the fl die set right its hard to get a loaded cartridge to just fall out of the chamber. Best wishes for good shooting

Thank you gentlemen seems things are easier than I thought , still not a done deal and so far the guys with the white wrap around sleeve coat cant find me . this would def be my last rifle build and now for the cash...……. where are those lottery winnings?

Thank you most of what I saw on .22 creedmoor was in very short barrels and this gives thought to stopping at 26 inches. Good point on twist rate and I will ponder and plot.

That is one pretty rifle! I don't think speed and accuracy are a one or the other my hope would be .50 or less for shots at 100 yds. My .204 No1V does way better than that. I have always admired the Farquarson type action and Daniel Fraser too . A walnut color laminate with stainless would be a real eye catcher. At this point im still dreaming and if im employed at Christmas this may happen. In my world the perfect optic would be a Unertel with external adjustments or the Lyman Target Spot from days gone by, haven't seen either for sale in years.

I have been doing a mental rifle build in 22 creedmooor intended for long range varminting. Action of choice is Ruger no1 Stainless with 28 inch .75 inch taper barrel. 3 groove barrel and laminate wood. 9 inch twist. The 69grn tmk at 3800 fps makes my brain itch! A donor rifle in 22-250 with a shot out barrel would be a way to do this somewhat cheaper. As is I think it would be a 3k USD build. Feel free to comment and any ideas I will consider, not committed yet maybe I should be?

By definition belling expands the case mouth the idea being just enough so adjust up slow!. Other than that total agreement on printed data in hand! Its hard not knowing the knowledge level of a forum user and guessing about whats known, on the shelf for purchase or just the odd thought. One added thought on belling, just enough that the base enters the case square not off center quit right there. seat first then roll crimp not a dual action. Crimp on the cannelure. Best wishes for good shooting. I know the die maker say dual crimp/seat possible but imo you will wreck less brass in two stages of work instead of just crimp/seat at the same time.

Cant say I want one but I do think the vents in my CZ550 stock help slow barrel heat. As for any better life idk it has 4400 shots down it , 22-250 and groups fine. Who knows for sure. For machine gun use I think that water jacket is great but no country I can think of uses water cooled machine guns now.

Well said, had I not been up after a 12 hr night shift I hope I would have said what you did with such clarity.

You will love Starline brass I use it in .44mag. Not knowing what powder is available limits my thought but I would not use bullseye in that huge case, I do use Accurate Arms No 7 and when that dwindles Alliant 2400 over a 240grn swc .

Cfe223 and Alliant 2400 purchased at some point 2012 to 2016?? Tbh I just don't know. Seems it found the darkest hole in the cabinet normaly used for storage of coffee cans and shop rags. Perhaps all it wanted was a cool dark soft place to raise its young.
