Hello I just discovered a mossberg 151k which is a 15rnd, tube feed semi auto .22. Mossberg made them for only a year or two in the early '50s. I havent fired it and was wondering if this is a last shot closed bolt setup? And to charge it just pull the bolt back like other semis? Do you load the tube thru the hole in the side of the buttstock or at the rear? Has anybody ever owned one of these models and what did you think of it? What would be a good price for a shooter grade + /-? Thanks in advance for the info. Cheers

Bolt does not stay open after last shot.

Uh... yeah. Load the mag. Pull back the bolt and let go. Pull trigger.

The hole in the stock... Uh, yeah. That's where you can fill the mag from.

I'd pay $100 for an old Mossberg in good cond. I have a 151MB made betweeen '46 and 50-something.... Shoots as well as any .22lr.
 
Great rifle, very accurate. Mine has a Bushnell Banner 1.5-4X Safari style scope, a sling, and a beautiful stock. shot a one inch group @ 25 yard with Remington Subsonics. make sure to clean the action every 100 rounds, other wise it sill jam more often. some high power rounds will cause it to skip one round and the go F/A during rapid fire; due to a loose spring-got that fixed quick.
Good find, Good gun.
Happy shooting
 
The 151 is a stock fed semi auto and a great shooting rifle. i have 3 model 51 and 151s but they are full wood to the muzzle but the 151K is the sporter stock version. I shoot mine very often and the bolt needs cleaned about every 500 rounds. Never had them faulter and are very accurate to 100 yards. value of mine, made in 1936, 1947 and 1948 is about $100-125 each depending on condition.. Many of them around and one is never enough...welcome to the club.
 
I have 3 - 151M Mossbergs. They are great semi-auto 22's. Very accurate and relatively trouble-free. The magazine in the stock is a nice feature, IMHO. No magazine out under the barrel and the feeding system is very direct. One of mine will shoot ½" or a bit better at 50 yards, the other two are only slightly less accurate. That's not bad for a semi that has not been altered in any way. I love those old Mossys!! Eagleye.
 
Thanks for the info! When I first got it, it was seized up solid. Turned out to be old grease which came off quite easily. I disassembled the rifle only as far as unscrewing the cap and pulling out the bolt and pulling the magazine spring assembly out. I didn't take apart the bolt or trigger group area. I cleaned and lubed the whole works. So now I think it is in good shooting condition and am looking forward to trying it out. SMLE 303 mentions running subsonic rounds through his 151. I would have thought there would have been cycling issues but I guess not! I'll get some high velocity stuff to make sure there isn't problems right off the start. I know my AP74 likes Velocitors and Mini Mags or whatever, needs lotsa lube and like the 1022 uses power rounds to run right. I agree that not having a removeable mag is a bonus and cuts out feeding lip problems not to mention showing up without the mag!!! and so forth. One thing I can't figure out is why there is a plastic trigger guard, which looks like OEM, on such a well made rifle. It feels good with the finger grooves but looks like the weak link in construction, mind you its been there for sixty years and is still in one piece. LOL Cheers

Another thing that sets them apart from the all wood stocks. I have never used any "high speed subsonic rounds"...Reality says that a 60-70 year old action would use the ammo of the period. I use Winchester 333s all the time in mine and they cycle great and stay cleaner than with many other brands of ammo. Being it is the pressure that activates the reloading cycle , there should be some residue build up. The gun will let you know when to clean the bolt .
 
That's a good point Winnipeg. I never thought that it could be set up for a 60 year old round! Pressure is the agent and I assumed the quicker the round the higher the pressure. Maybe the pressures achieved today was only a twinkle in somebodies eye. Never assume anything! Shoot first talk later. Cheers
 
Please let me know how you make out with it. I really enjoy my old girls and they have done the job on varmints countless times ..Target shooting with the 1936 model is great fun. (open sights)
