I have a Remington 700 BDL that was converted to 6-284 from a 6MM. It isa tack driver. It had no bottom metal. A friend gave me all the necessary parts from a 243. I didn't realize it but with the 243 box and follower 6-284 bullets won't go into the magazine they are to long. How can this be remedied? Thanks from a 72 year old real novist. Lou
