« on: September 22, 2009, 04:11:39 PM »
i bought a 550 this week. not free floated and no rings. minnesota model it says in the manual.

only $495 new though so still a deal.

put a bushnell legend 2-7x33 on it ad going to sight in this week.

i free floated the barrel and bedded the action.

Awesome mjbgalt. Congrats on a fine new rifle. Bet she is going to be a keeper.

i dunno yet. went to the range tonight. my lord is this thing heavy! i think i am going to whack 2" off the barrel...

bedded and free floated already, and adjusted the trigger.

i got it dialed in at 50 yards as i ran out of light.

i will try again this weekend, this time to work up a load.

I just don't see the CZs as being heavy; I look at them more as being "built," as in well built. ;)

Not even shot it yet you butcher the factory bedding  :'( for all you will ever know it would have shot wonderfully as it was  ;) OK I can understand trigger adjustment but??  ???

As for the rifle being heavy  :o Hmmm I wonder what Old Townsend Whelan would have thought of it. I had an idea he would say go and get fitter  :D He certainly didn't think much of Featherweight rifles and especially buggy whip barrels!

And no I am not a fan of floated barrels  :-*.

I have a CZ 550 American in .243 also.  It is a bit heavy (8 .75 lbs with scope) due to the weight of the walnut stock but nothing I can't handle.  Never heard of the Minnesota model before.  Usually the 527 and 550 CZ's come with rings except for the varmint varieties.  One thing I can tell you my stock .243 will shoot 75 gr. HSM Nossler Ballistic Tips in a clover leaf (under .5") at 100 yds. and opens up to about 1" with 95 or 100 gr. anything factory (I don't reload).  I own 3 CZ's and the only thing I had to do to get the rifles shoot better is to shoot it more.  All of my CZ's shot better the more rounds I put through them.  This seems to be normal.

Tango, I had my 550 apart the other night to do a polishing job with Renaissance Wax on the stock and Flitz on the metal and came to the conclusion that if CZs are heavy, it's because of the metal. Didn't actually weigh the stock, but it seemed typical in weight - about the same as a Remington CDL stock. The real heft came from the barreled receiver. No plastic to be found on the 550. Even the mag well is steel. Heavy steel at that. The barreled receiver felt nearly as heavy as the barreled receiver of my Rem 700 with a varmint contour barrel. Nothing official, just an observation that lets me enjoy the CZs even more. Sounds like your .243 is a keeper for sure.

Your right about it being all steel.  Even the mags for my 17HMR Varmint are heavy gauge steel.  One of the reasons I like them so much is they are built solid.

now brit, i am foolish AND fat? lol

i floated it because it had the barrel heavily pressing against only one side of the stock. i am not going to shoot it in 60 degree weather and then find that in 15 degrees it shoots differently.

i have bedded and free floated just about every rifle that's come my way and only one or two didnt shoot great afterward.

if it was a full length stock or was bedded correctly already, i wouldn't touch it.

i shot the other night again, found a few loads that would go less than 1/2" at 50 yards (the distance i use for load develtopment- takes me shooting badly out of the equation).

Hmmmm fat is I believe a term which could be applied to me  :-[ I am certainly carrying too much around the middle section  ::) and according to the Docs chart am 70lbs overweight either that of about 10" too short  :D. I just got on the scale an they groaned a bit around to 226lbs..

As for the floating .................... well I swallowed all the guff years ago and did as you with a new converted Swedish Mauser sporter I brought. A commercial conversion with new M38 barrel so I floated it and it shoots very well but over the years the extra weight of tha floated barrel has compressed the bedding and now it need a complete bedding job  ::). A while after I acquired that Swede I got another 6.5mm rifle but this time a classic  :) it's a Mannlicher Mdl 1892 built into a Best Sporting rifle by Rigby's of London chambered in 6.5x53R (.256 Mannlicher). Of course it was not floated and after a trip to Rigby's for a clean and service (the trigger mech was full of crud, lint and grit  :'() they re-blacked the buttplate and trigger guard/magazine case and even found me a box of original Kynoch .256 rimmed ammo  :D.

I shot some of that ammo to check sight regulation, it has fixed express sights, stand for 100 and flip up leaves for 200 & 300 yards, with that Kynoch ammo it was on at 200 yards so I then developed a handload using Hornady 160 Grn RN bullets to duplicate it with Rel 19 powder. After over 100 years the bedding is fine and the rifle shoots to the sights. No scope but hey  ;D.

It was then that I started to re-think the free floating barrel business and started to test the other rifles I had. A Century Arms sporterised P-14 was the next test case. The stock was poorly, i.e cheaply inletted, so a bedding job was done on it and the barrel was floated on this one and yes it shot quite well. Being a 303 I shot it with some good Greek HXP69 ammo and with a 4x40 scope it even shot well at 600 yards. however another P-14 conversion in 303 I had but this time by Parker-Hale with target sights even with it quite severly erroded throat would out shoot it at 200 yards. Holding the Vee bull on a Bisley target was childs play with good ammo and the PH5B rearsight that was until the throat errosion got to be about 5-6" long and accuracy tailed off  :'( a re-barrel was called for but prooved to be too expensive so the rifle was canibilised and removed from my licence. That rifle had a nice streaked walnut stock which I still have and of course was pressure bedded in the barrel channel and with the ERA barrel outshot the new barrel on the Century Arms rifle. I no longer have that particular century rifle as it was sold to make room for something else several years ago now. I do have my nephews one which was "new" when he got it but the chambering job was over tight and handloading for it a nightmare so when it became mine i had it re-chambered to 303 Improved and it's still a work in progress.

I have 5 rifles that have floated barrels, three of which came that way from the factory and they are:-

P-H 1200V
Mauser M96 Slide Bolt
Sportco M44 single shot target rifle

The other two are:

Century Arms P-14 sporter (303 Imp)
Swedish Mauser sporter conversion

None of whch is my most accurate rifle.. Now since moving here I am fighting the dreaded "rust", has something to do with being closer to the sea and the fens I suppose. It's just plain damper and more humid here. Now whenever I acquire a new,to me, rifle I shoot it first before looking to improve or sort any problems that show up in the testing. I have spent hours trying to correct some ones butchery on a .243 BSA Majestic. The walnut is a very nice Honey colour but some previous owner had wrecked the bedding and barrel channel in an attempt to free float it. The rifle shot patterns and I have had to rebuild the barrel channel with wood filler  :o it's now pressure bedded and shoots much better. once I save up the funds it will off to a riflesmith I know to have a professional and hopefully un-noticable repair to the barrel channel. My work was just to prove it could be done and check that pressure point bedding improved the grouping. It will also give the gunsmith a ball park figure of pressure to work with so should cut the time and cost slightly.

Have fun with your new CZ and if your happy I suppose that's all that really matters  ;)
