    I grew up helping my dad reload, so I have an idea of what I'm doing but it has been a while. Getting a RCBS set up but I don't have any components other than a lot of once fired factory casings. I will be building a load for my Winchester Extream weather ss .270 win. It has the 1 in 10" twist. What whould be a good starting point as far as what bullet, powder, primer. I will also be laoding for my wifes .243. So would prefer to buy a powder that would also work well with it. I'm thinking 210m primers and maybe H4831sc power, what do you think??? Also what kinda bullet????

    Thanks for the help!!

    What will you be hunting? How far do you plan on shooting?

    Mostly deer and exotics in Texas. If I get lucky someday I'd like to make it to an elk hunt somewhere.

    As far as distance, well ultimatly I would like to get good enought to shoot steel out to 1000 yards but that will be a while. And Animals out to 600 yards.

    Right now I am shooting 300 yards and holding about a 4..5" group. Hopeing to bring that tighter with the reloads.....

    H4831SC works well for both calibers.

    Well, my best 270 load to date is the 150 Berger VLD with IMR4350 and a 215M primer with weight sorted prepped brass and turned necks.

    H4831SC is one of the top all time powders for the 270 with any 130, 140, or 150 grain bullet. It also works very well in the 243. When I loaded for a friend our best load in his 243 was with AA3100 and the 95 gr NBT.

    I am a huge fan of the Barnes bullets as well and have one rifle dedicated to shooting only Barnes bullets. The 2 loads I've settled on are the 130 TSX with 57.0 gr Re19 and the 110 TTSX over H4350. Both with WW brass and 210M primers.

    Thanks for the replys.

    I have read that depending on the twist of the bbl will depict what bullet will work best. I am assuming they are talking about the bullet lengh not weight?? Can u educate me on what exactly they are talking about??????

    Well, with increased wt you get increased length so they go hand in hand. To the best of my knowledge almost every 270 Win chambered rifle comes standard with a 10T.

    Don't worry about that in the 270. The only time to consider a faster twist is if you reload bigger bullets like the 165 matrix

    So is it that the faster twist will shoot longer/ heavier bullets better or worse than a slower twist?

    I think this will come in to play when I start in on my .223. Don't know what the twist of it is yet...

    The faster the twist the heavier you can go. The faster twist is what stabilizes the bullet.

    The other week I have build a load for a Remington 700 gun. The shooter is all new to riffles so my object this time was to help him develop skills and not to break bullet speed records. Accuracy and gun handling was of my concern. I made 21 possible bullet and powder combinations using the 130 grain soft Remington partition Bullet as a starting point, and after few hours, I had a winner. The first set was the most accurate and just a pleasure to work with. The final load was a 43gr of imr4895 with a 130 gr Hornady interlock bullet. This was a light load for the gun. Velocity was about 2600 ft/s. On the other side, I was impressed with the performance of Varget powder loads, most of them went over 3000ft/s. This is a plesant cartrige to work with. Check the barrel twist rate, its lenght, those things will limit your maximum bullet weight. If I remember the factory original load was 130 gr. Start there and then go up.
