stuey Posted April 27, 2009 Report Share Posted April 27, 2009 Noticed the groups on my hmr getting gradually worse, so decided to float the barrel. On inspection, the forend of the stock was really tight against the barrel. Took ages to sand down the wood in the barrel channel, but now the wood isn't touching the barrel. Problem is, the stock, despite being wood is flexing when I use the bipod off the bonnet and under these circumstances, the wood and barrel touch. So: a. is there something wrong with the stock b. do I need to remove more of the wood from the barrel channel so that even with the flex, the barrel/wood don;t touch. What annoys me most is its a left handed stock, and I would rather just have a synthetic, but nobody seems to do a left handed synthetic stock for the CZ HMR, or any left handed hmr for that matter; unless anyone knows different. cheers Stu Quote Link to comment Share on other sites More sharing options...
Beardo Posted April 27, 2009 Report Share Posted April 27, 2009 keep sanding - you need to have it clear when it's resting on the bipod Quote Link to comment Share on other sites More sharing options...
Billy. Posted April 27, 2009 Report Share Posted April 27, 2009 Is it really just as easy as sanding it down, Nick?! Quote Link to comment Share on other sites More sharing options...
Baldrick Posted April 27, 2009 Report Share Posted April 27, 2009 I have a true left-handed CZ .17 HMR. Anschutz, Savage and Cooper are the only other manufacturers to produce an L/H .17 HMR. I sanded out the barrel channel on mine and resealed it, making sure that I got about 2mm clearance between wood and steel when supported by the bipod. I am no expert on stock-work, but you may be able to sand out a deeper channel and add a layer of acraglass (or other resin reinforcement) to minimise the flex. If groups are gradually declining, it may be your cleaning regime that needs a re-think. Quote Link to comment Share on other sites More sharing options...
stuey Posted April 27, 2009 Author Report Share Posted April 27, 2009 Ok, cheers, will take a bit more out. Did anyone else find that it took ages to sand? As to cleaning, have just hoppes borefoamed the barrel and then ran a bore snake throughit. Will be seeing if these two things help improve things. Will put a few rounds down it this weekend as see if the groups come down as i fire a few rounds down the newly cleaned barrel. cheers Stu p.s. I take it none of the left hand manufacturers have a synthetic option? Quote Link to comment Share on other sites More sharing options...
Baldrick Posted April 27, 2009 Report Share Posted April 27, 2009 p.s. I take it none of the left hand manufacturers have a synthetic option? Nope, none of them. You might be able to buy a laminated after-market stock from Richardsons. Quote Link to comment Share on other sites More sharing options...
Beardo Posted April 27, 2009 Report Share Posted April 27, 2009 it is really that simple... he uses a special tool, but sandpaper does it http://www.wonderhowto.com/how-to/video/ho...a-rifle-204317/ Quote Link to comment Share on other sites More sharing options...
Guest RemmySPS Posted April 28, 2009 Report Share Posted April 28, 2009 Go to a builders merchant and buy some really coarse aluminium oxide paper. It comes on a roll and you can buy it for @ £1 a metre. Wrap it around a bar of the correct diameter and sand away until the bar fits the channel.

If you have just borefoamed it you can expect your grouping to be all over the place for 30-50 shot's Mine shoot's like a blind man on a galloping horse is pulling the trigger after cleaning :blink: Quote Link to comment Share on other sites More sharing options...
stuey Posted July 30, 2009 Author Report Share Posted July 30, 2009 Well, eventually got out to test the hmr since floating the barrel. After a quick 35yd zero, I took 4 rabbits for 5 shots including a nice 130 yder. Along with the barrel floating and a change back to Remmington ammo from Winchester, my confidence is high once again with this gun. Now looking forward to the rest of my 800 acres to have the grass and crops cut. I forsee this gun getting well used over the next month or so!! stu Quote Link to comment Share on other sites More sharing options...
