Re: 7mm RUM or 338 Lapua Mag for Long Range Pdoggin
I have to say, in my endeavor to become a better long range shooter, I have two things that I have concluded. 7mm is an excellent caliber for long range work no matter who tells you it isn't. The other thing, is that bigger isn't necessarily better. I know of two guys right now that use a 300 Weatherby Imp. and another using a 300WSM trying to be in the 2mile club shooting pdogs. Speed helps, but it isn't everything especially when you are shooting something as little as a pdog. If you were going after elk, I would be right on board with you.
If this is a dedicated pdog gun, price of reloading should also be taken into consideration. The size and class bullet you are planning on shooting are pretty expesive. My cousin gets 65 rnds per pound of powder with his .338 Lapua. He loads 100.1 grns of Retumbo with 250 Lapua Scenars and 250 SMK's. He figured a cost of 140.00+ per 100 to reload.
With my 300WSM, I load 200grn SMK's with 61.5 grns of RL17. I load for around 62.00 per hundred rounds. That equates to $.62 per round. The Lapua loads at $1.40 per round. That in my opinion is an expensive pdog round. I'm just trying to show the reality of the cost into your decision.
For what you are doing those rounds will work admeriably, but I thing you might want to consider a WSM caliber, or something of the like. I am considering a 7mmRM to achieve the same goals for ground hogs. The reason I am choosing this round is due to the bigger boiler room over the WSM. Barrel life is going to be longer as well. Now if you are considering to go for big game as well then hook your self up with either caliber and you won't be disappointed. Sorry for being long winded.
