I am having a problem here. I am wanting to put a large ss bolt handle (from a flat rear apparently) on my 7-08 Stevens s/a (round rear) that I am re-barreling to a .204. I took the bolt apart, switched out the bolt head, and bolt handle. When I went to put the bolt back in the rifle it was really hard to close (probably twice as hard as it should be). I took that bolt handle off and put the original small one back on and it works fine. Is it something with the bolt handles being slightly different? I have swapped bolt handles on my other rifles but they were for round/round , flat/flat etc.. and matched everything correctly. I am confident that I have everything reassembled correctly. Any input on this is appreciated. Thanks in advance!
