    I have been fooling with a CDL 'in 7mm ultra mag since about November.groups suck, trigger sucks, etc. I adjusted trigger and got it acceptable for now, but a better one to come later. Meanwhile, my groups were telling me that I had a bedding issue. Well,I thought about full bedding the action, and floating the barrel, but I remember reading that some " factory" barrels like pressure on the front end. My rifle had this now, but I don't think it was constant. I went to the range yesterday, but I put a business card under the barrel, on top off the raised boss in the forward stock. I shot the tightest groups that this rifle has fired to date. Groups at 100 ran in the threes, at 200, .496. So the question is, should I pillar bed, and then fully bed the action, and add a shim to the front end, or just glass bed action and float barrel????? What is the concensus on floating the barrel versus shimming front . I have been spoiled with aluminum bedding blocks in most off my other guns and haven't hade bedding issues in awhile. I was considering dumping this thing, cause the accuracy just was not there. Thanks guys, AIM SMALL,MISS SMALL, 7STW. lightbulb

    I have the same dilemma with a CDL in 257 wby. I had the action glass bedded and the barrel floated in a B&C stock with the aluminum chassis. Also added a Jewel trigger. The rifle grouped better or the same in the wood stock with the pressure pad at the end of the stock. I am not sure if I should get dies and try reloading or find someone not as picky as I am. I am getting right around 1.25" 1.5" groups with most factory ammo. I have been thinking of putting some bedding material in the same location the factory stock had and seeing if it helps. Let me know what works for you.

    A rifle that shoots better with pressure than without means one thing, There is a bedding problem! Factories often do this as a bandaid approach. If it is properly bedded, there is no way that it should shoot any worse, and chances are, it will shoot even better. Having said that, .496 @ 200 yards isn't too shabby so if you bed it, make sure it is done properly.......Rich

    Thanks for your input, well taken. In your opinion, should I pillar bed and float barrel, or pillar and build up the pressure point. I was thinking about taking the barreled action out and install it on one of my Sendero stocks to see how that effects it. I have bedded several wooden stocks, before, so if I have to do this , I will. I am just wondering about the effect of leaving the pressure point, or taking it out. What do you think of pillar bedding, versus plain old straight glass bedding. I have read all the articles on installing the pillars correctly, and feel confident that I can do so. Any thoughts appreciated. Thanks. 7STW. AIM SMALL, MISS SMALLlightbulb

    I would pillar bed it and glass it in as well. Cut the stock out to clearance adequately before you bed. You can wrap the forend, near where the pessure bump is, with tape to make sure you have clearance after it is bedded. You might try glassing the first couple inches of the barrel when you bed it as well. If for some reason it doesn't shoot, you can always replace the pressure bump with epoxy........Rich

    My 7 Ultra CDL was bedded and floated when I got it, so far it hasn't shot any groups as good as yours but it will stay around .6 - .7 at 200 as long as I don't get it hot. I thought about sticking it in a glass stock but I really like the CDL stocks, IMHO they are the best looking Remingtons since the 725 deluxe. I think a pressure point on the forend would cause problems when shooting off a bi-pod.

    Nimrod, I am right with you on that. I bought this rifle in this combination, because I wanted the CDL in 7RUM. I had forgotten about bedding issues that come with wood stocks. ( Senderos and 700 p's don't have that issue) P/S, I just saw a BEAUTIFUL 725, B grade. Very nice, not for sale. Anyway, I just have the debate on the pressure point,but I am thinking that I am going to pillar and glass bed the action, out to about 2 inches forward of the lug, then full float the barrel. You are right about the bi-pod if I was to use it. Thanks for the reply. AIM SMALL, MISS SMALLlightbulb:) 7 STW.
