    Thinking of a 800 yard and closer rifle build for deer and varmits. I want a caliber that is know to for its easy load development and easly obtainable low es. Any ideas? Thanks for the info up front to.

    I don't want this to come out wrong but all calibers are capable of this, you just have to be persistent in your endeavors. Can you maybe off up some more considerations for everyone to help you out?

    In my experience bullet selection has been the driving factor in all the questions you asked. Look forward to helping you.

    Heck yes no problim at all. I just figured i would save myself a lot of trial error. I have a 243wssm that i had great luck with es less then ten real fast. I wish i had more time to devote to load development, i get a couple hours a week. I guess i would like to find a round that i get get low es with real fast. Iam very carefull to have everything consistant. Ive read and bevoted so many hours to load development and still most times struggle to achieve low es. In my off time not working and parenting i eat sleep and breath trying to make a few of my rifles shoot low es to no avail. You name it i am either doing it or have tried it. I guess i was just hoping somebody would say this caliber with this power and look out. If everything else is the same your low es will be easy to obtain.

    There are lots of good calibers that could fit your requirement. There are no hard definitions but I think deer and varmits at 800 yards would be considered long range by many. As long as you are not talking high volume prarie dog shooting, I will throw in my vote for the 6.5x284. I have had the easiest load development getting exceptional accuracy and tight ES in two rifles very quickly, and, had several friends duplicate the results without much work using pretty common recipes. It will flatten a deer out to 1000 yards and have no problem grouping well enough to hit a groundhog at the same distance or further with a properly chambered, quality rig. Bullet choices cover a nice range for both varmints and deer, or you can use a 140VLD for everything. Ballistics are superb, and recoil light. iMHO.

    I read that u have use the powder that gives you the most case fill. Also a few guys say that slightly compressed will give u the lowest es.

    oh, come-on I wanted to hear it.

    as to the op, I'd go 280 rem or 7-08. The smaller 30's run out of steam early, and people are already talking 6.5 so I'll go elsewhere. The 270 is great accuracy wise, but it's pulling teeth to get sub 40-50 fps x out of it. Doesn't seem to screw up the groups too much though, so you may wany to loosen your criteria a bit.

    Haha ok, i was thinking 6.5x47 or 6x47. I dont have one but i would sure love to! Both have Lapua brass, supposedly great accuracy, very efficient, awesome barrel life for high volume varmit shooting, and the 6.5x47 has enough for varmits and deer to 800 yards but i am not sure if the 6x47 has enough umph at that range.

    Im not sure how the ES for either, thats why i deleted my other post.

    I read over on accurate shooter , the smaller the case the more easy it is to get fower es. I have one rifle in a large 338 caliber that iam having a very hard time getting es below 36 fps with 8 shots. Gona try retumbo because they say you will fet a few more grains case fill iam gona try it i guess.

    I'm partial to the 280AI. I just had a new one built and it definitely meets your qualifications. It only took me 30 shots for break in and load development. My most accurate load is Nosler brass, CCI 250 primer, 60.0 of H4831SC, with Berger 168vld at 2850fps with ES of 8. While working up to my max pressure with this powder I loaded 6 cases with increasing charges of H4831SC and shot them all into a 1/2 moa group. The group below is 0.205 center to center.
