Thats a fantastic looking rifle , very NICE , like the 5rd mag , the only thing I would change would be calibre ( 375/408 ) and std barrel ,
I have some 375-408's in the works, personally with what bullets are available the 338 is a hands down winner over the 375 version. When more 375 long range bullets are available, then there will be a slight advantage.
I have a 375 Snipe-tac just waiting to be put together, i am designing a new stock system just for that rifle. It will be similar to this one only an internal magazine system will be used. The action will be shorter and still feed the 408 cases. Look for that in the coming months.
What's your opinion of the 375 vs the 338 at this time?I'm having a 338 edge built right now,but want to build an ultra long range rig later this year.So far,I haven't seen anyone say how the Sierra 375's are shooting out past 2000yds,and I'm curious if I go with a 375, will be able to get good bullets for it?You mentioned the 338 having similar capabilities to the 375.Do you think a 338CT with the 300gr Sierra's,or possibly one of the Wildcat aluminum tipped bullets should be to do what the 375 SHOULD be capable of?Thanks,Jack
At this time the new run of 375cal SMK's have not arrived, don't know whats going on. This is what has transpired in the last few days with three different customers with 338snipe-tacs. One in Montana, one in Tennesee, and one here i was testing for this post. Montana guy is just getting his bbl broken in, but the rifle is shooting lights out he said. The Tenn guy called today and said at 560 he fired three shots that a quarter covered the group, 140grns of BMG50 just under 3400fps. The rifle i just got through testing i fired the smallest group that wasn't a BR gun, three shots at 100 was .077, hard to measure that. At 705yds it was just over an 1.55" group. This is just the accuracy side of the round, at speeds over the 3300fps your energy is way up there. The alum tipped wildcat bullets will make this chamber even more impressive at longer distances, 2500 and out. But you will need a faster twist barrel. These rifles had three different twists, 10, 11 and 11.5"
All shot great using the same loads.
At this time you are limited on bullets for the 375cal, early SMK's have thin jackets and cant take speeds over 3100fps. The new ones are supose to be .100 longer and heavier jackets. Or you got the monolithic LRB bullets in 350grn. I supose the alum tipped wildcats will be the ticket, when they become available.
The 375 will have a little bit longer barrel life over the 338cal, but it depends on the desired use of the rifle. I was going to build a 375snipe-tac for myself, but i like the idea of cheaper bullets the 338 has. Its not a heavy use rifle in the first place.
I fired one shot with out the buttstock, the recoil was not that bad, but even then the "pistol" weight is 15#. 32" pistol, 338 snipe-tac, extra long range!!!! I hit the 550yd gong with no trouble. I would of done more and pics but it was 50deg and started to rain. Maybe later on i can try it again when the rifle returns from its hunts in Wyo.
I dont know if a 20" barrel in this round would be worth the waisted powder, it sure would be a conversation piece!
