    Quick question

    Kirby did you open up the throat of the gun , to get more use out of the case ?

    Or did you leave the length more basic to use with the 265 type bullets.

    Always wondered because I would like the idea of getting a touch more out of this round.

    God Bless

    Jeff

    Re: NEW 338 Allen Magnum Xtreme Heavy Sporter for sale

    The rifle was actually built with a throat set up for the 300 SMK set at an OAL of around 4.250". Interestingly enough, the 265 gr Barnes TTSX has a very similiar bullet length and ogive length compared to the 300 gr SMK.

    Being a single shot, this throat will also work extremely well with the Berger 300 gr Hybrid, in fact with this bullet, it would be seated out around 0.100" farther out of the case then the SMK or Barnes so you can generally pick up a bit more velocity with the Berger compared to the SMK. The Berger also has a bit shorter baring surface so that also frees up a bit more velocity.

    On averge you will see around 50-75 fps more velocity with the Berger then the SMK.

    In short, this rifles throat would be ideal for any of the following bullets:

    265 gr Barnes TTSX
    280 gr Barnes TTSX
    285 gr Hornady HP match
    300 gr SMK
    300 gr Berger
    300 gr Accubond
    Any of the Rocky Mountain bullet

    Pretty much any bullet over 265 grains would work perfectly will in this throat and offer full performance.

    In testing the 300 gr Accubond, I have found that because of its VERY long baring surface, its a relatively slow bullet compared to same weight match bullets. It will on average run 50-75 fps slower then the SMK in most rifles. This is not a real bad thing if your needing the terminal performance of a bullet such as the Accubond, a 300 gr Accubond loaded to 3225 to 3250 is one hell of a potent big game hammer.
