I know that this is a little far fetched, but let me know if it is possible and probable. I have a 300 weatherby in the accumark. I just ordered a custom 257 and have a 3006, so I am looking for something a little larger than a 30 caliber. I would like to get a lilja barrel and have it chambered for 338 ultra. Do you guys think that there will be any feeding problems or do you think that I would be better off just buying a remington 338 ultra and settling for the barrel on it.
