Several years ago I had Steve Holborn of Warren ONT rebore my sporter P17 Enfield from 30-06 to 338-06. After much reading about what caliber to make I settled on the 338-06 over the 35 Whelan or 375-06. I bought the rifle used from someone who did not take care of it very well. The bore was pitted, but the sporter stock was in beautiful shape, therefore I bought it for my project. Steve rebored it, tapped it and reblued it to a beautiful finish. I refinished the stock. It is a gorgeous rifle and extremely accurate. Holborn does superb work and is good buddies with Ron Smith of Alberta, who also does these type of conversions. I highly recomment Holborn. It now is my primary rifle for big game. Would not mind another project rifle in 358 Norma Mag. Need to find a P14 Enfield, if anyone has one to get rid of.
